designed for armor-piercing, using the Monroe effect. It has approximately
the same configuration as the Mk 1, but can be readily identified by the
flat nose on the fuze which is designed to prevent richochet. It is
filled with .89 pounds of Composition B. It uses the Mk 181 fuze which
is point-initiating and base-detonating. When assembled it is classified
as air-to-ground, service, armor-piercing

MINES
OBJECTIVES:
To learn identification, function, safety precautions, hazards, and safing proce­
dures for US Antipersonnel and Antitank mines. To learn the assem bly, operation, and
field techniques of the M D -M Mine Detector.
INTRODUCTION:
Mine warfare dates far back into military history. It originally consisted of tun­
neling under strong fortifications and blowing them up with explosive charges. Since
modern weapons have much more destructive power and ability, this method is rarely
used by modern arm ies. However, mine warfare, as employed by the Viet Cong in
Viet Nam, has proven that no method of mine warfare is obsolete.
Mines may be laid in standard patterns or in random patterns. Mines have been
removed and used against the forces which originally placed them. This is because the
mines cannot discriminate between friend or foe. In addition to this, an armed mine
never needs the rest or relief that an armed man does.
In this chapter we will cover representative samples of all known US mines em­
ployed in Viet Nam.

Grasp the handle in hands and
make wide sweeping motions from left to right while slowly walking forward (study fig­
ure 7-22).
d.
Using the Detector in the Prone Position.
Assume the position (figure 7 23) and make wide sweeping motions while slowly crawling forward.
e.
Buried Metallic Object Encountered.
A noted increase in the headset sig­
nal is an indication that a buried metallic object is in this particular area. Proceed to
locate the exact location as follows:
(1) When a sharp increase in signal is heard, move the detector head
slowly from side to side. Increased signal will be heard as either side of the detector
head is passed over the metallic object. A decrease will be heard as the center of the
detector head moves over the buried object. If no decrease in signal is heard as the
center of the detector head moves over the buried object, a saturation condition exists.
If this occurs, raise the detector head 1 to 2 inches higher and repeat the sweeping
motion. If necessary, raise the detector head until a definite change in volume is evi­
dent when the detector head moves over the buried object. When this occurs, the
detector head is directly over the object.
WARNING
Always keep the detector head parallel to the ground during a
search operation. Never allow the detector head to drop or
rest on the ground during mine detecting operations in a
suspected area.

AIRCRAFT EGRESS SYSTEMS
OBJECTIVES
To learn:
1. To identify cartridge-actuated devices used on aircraft egress
systems.
2.
fhe function of cartridge-actuated devices.
3. Safety precautions, EOD safing procedures, and EOD disposal pro­
cedures for these devices.
U. The quantity, type, and function of devices in the egress systems
of the F-100, F-105, F-U, and A-l series aircraft.
INTRODUCTION
All jet aircraft, and in some instances propeller-driven aircraft
currently utili-e^ in SEA, contain an egress system. It is imperative
to know th'-^e Bys&eisz thoroughly from an EOD viewpoint, not only for the
safety of all personnel involved, but also for the immediate dearming of
the system itself.
Some of the aircraft egress systems can be initiated externally
(canopy removal) and some are limited to internal operation. It is the
EOD man's responsibility to be completely knowledgeable of all aircraft
egress systems for which he is responsible.
INFORMATION
CARTRIDGE-ACTUATED DEVICES
1
Initiators
Initiators are cylindrically-shaped items designed to provide the
necessary ballistic gas pressure required to activate other items. They
are manufactured in different types and use two methods of operation.
a.
MECHANICALLY-ACTUATED INITIATORS. These initiators are actuated by
pulling the mechanical linkage which in turn cocks and allows the firing
pin to fire the explosive charge. The gas produced by the burning pro­
pellant flows through a tube and/or hose to initiate Mother item.
b.
GAS-PRESSURE ACTUATED INITIATORS. These initiators are operated by
gas pressure from another source. Pressure to the inlet port breaks the
shear wire and forces the firing pin against the cartridge. The gas pro­
duced by the burning propellant flows through a tube and/or hose to
smother item.
Initiators may be either instantaneous or delayed in their action.
Instantaneous initiators are used for any operation that requires immedi­
ate action. Delay initiators are used for any operation that requires a
delay, such as seat ejection, seat lap belt release, etc.
CAUTION
Although initiators contain less
than one ounce of explosive ma­
terial, they are extremely haz­
ardous and should be handled with
caution.
2.
Removers
Removers are used to remove the aircraft canopy by means of an
explosive charge
like initiators, can be actuated by different
methods.
a.
COCKED FIRING PIN ACTUATION. A cocked firing pin, held in place by
the Ml exactor, can be used to actuate the remover. Gas pressure to the
inlet port of the exactor removes the pin from the firing head of the
remover, allowing the cocked firing pin to fire the explosive charge.
CAUTION
Never remove the Ml exactor from
an item to safe it. Removing the
exactor will withdraw the pin re­
leasing a cocked striker. Always
remove the item and exactor as a
unit.
b.
GAS-OPERATED FIRING PIN ACTUATION. This type of remover is very
similar to the gas-operated initiator because it has a firing pin held
in place by a shear pin. Gas pressure applied to the inlet po^t forces
the firing pin to break the shear wire and proceed downward to fire the
explosive charge.
c.
ELECTROMECHANICAL-BALLISTIC REMOVERS. These removers are designed
to raise and lower certain aircraft canopies under normal conditions
during ground operation and to jettison the canopy during an emergency
escape while in flight or on the ground.
8 -2
During normal ground operations the remover is functioned by elec­
trical means; during emergency escape, it functions by the gas pressure
supplied by an explosive clartridge.
3.
Thrusters
Thrusters are used in the egress system for assorted purposes such
as equipment stowage, hatch jettison, seat positioning, canopy unlock,
etc. Gas-actuated thrusters function in the same manner as gas-actuated
initiators. When gas pressure is supplied to the inlet port, the firing
pin is propelled against the cartridge.
CAUTION
The explosive content of thrusters is
comparatively small; however, their
method of operation and their type of
construction make them very hazardous
to handle. Extreme caution should be
exercised at all times when handling
or removing them from aircraft.
A.
Rotary Actuators
Rotar; acuuaior: are designed to forcefully separate the crew
member from the seat after ejection. Gas pressure from an initiator
causes the cartridge to fire; the resulting gas pressure exerts force
on the bottom of the ball screw. Motion of the ball screw causes the
ball nut to rotate and draw the webbing taut.
5.
Catapults
Catapults are telescoping ejection items designed for emergency
ejection of aircraft personnel. They can be used for either upward or
downward ejection systems. Catapults operate by various methods in a
manner very similar to initiators and removers.
a. MECHANICALLY-ACTUATED CATAPULTS. This device has a cocked firing
pin which is held in place by a sear lever. Upon rotation of the lever
an internal shear pin is broken, releasing the cocked firing pin which
in turn fires the explosive charge.
b. GAS-OPERATED CATAPULTS. These devices operate exactly the same as
the gas-operated removers (see "Removers").
c.
MECHANICALLY-ACTUATED CATAPULT, NAMC (NAVY), TYPE I AND TYPE II.
These devices function in a manner similar to that of the Air Force cata­
pults. The pulling of the mechanical linkage cocks and releases the
firing pin. The safety pin is removed by the canopy when it leaves the
aircraft.
8-3
d.
ROCKET CATAPULT. This device is a 2-stage ballistic item consisting
of a cartridge-powered catapult and a solid propellant rocket motor. Gas
pressure introduced into the inlet port shears the firing pin sheen: pin,
forcing the firing pin against the primer and firing the cartridge. The
catapult portion, actuated by gas pressure, pushes the ejection seat up
the guide rails. The rocket motor is ignited by the catapult gases just
prior to separation from the catapult tube.
CAUTION
Seat ejection catapults contain a larger
amount of explosives than the other
devices - often as much as 7 ounces.
The very purpose of these items is to
move heavy objects; therefore, anyone
handling them should be thoroughly
familiar with their construction and
operation. They should be handled with
the utmost care at all times.
e. ROCKET PACKS.This item is mounted under a seat and gives it a
sustained push up and away from the aircraft. It is a mechanically
initiated item and has many tubes of propellant and multiple venturies.
CAUTION
Due to the amount of propellant and its pro­
pulsive ability, the rocket pack is an extremely
hazardous item.
f. DROGUE GUNS. These devices contain an explosive charge used to
eject or propel a metal slug. The slug is usually used to deploy a
parachute.
CAUTION
NEVER stand in front of or over a slug
while working on a drogue gun.
SAFING PROCEDURES
Saflng procedures covered in this portion of the study guide are
general in nature and pertain only to individual items of the egress
system. Safing procedures for the entire egress system will be dis­
cussed later in the portions of the study guide which pertain to indi­
vidual aircraft.
1.
Initiators
a. Replace the safety pins if at all possible.
b.
Disconnect or cut the hoses and replace the caps.
c . Due to the condition of certain initiators, it may he necessary
to gag moving parts.
2.
Removers
The safing procedures for removers are the same as those for
initiators discussed above.
WARNING
Never remove the Ml exactor from the
canopy remover.
3.
Thrusters
1.
4.
Disconnect or cut the hoses and replace the protective caps.
Catapults
The safing procedures for catapults are identical to those of
initiators and removers discussed above.
SAFETY PRECAUTIONS
Observe the following safety precautions when safing aircraft per­
sonnel egress systems.
1.
Use quick disconnects whenever possible.
2.
Insert maintenance safety pins whenever possible.
3. When cutting or disconnecting is required, cut as close as
possible to the outlet ports of initiators, inlet and outlet ports of
boosters, and inlet ports of removers and catapults.
k. Insure that the hose ends are taped or wired to a fixed object
to prevent whipping action.
DISPOSAL
For disposal purposes, aircraft explosive items fall into the three
following general categories:
(l) items which must be disassembled to
accomplish disposal, (2) items which are disposed of by detonation, and
(3) items which are disposed of by burning. The most common means of
disposal is by burning.

F100-D AIRCRAFT
The F-IOOD aircraft uses a conventional egress system for the single
seat. The escape system, illustrated in figures 8-1 and 8-2, can be initiated
by raising the seat handgrips and pulling the canopy emergency jettison
handle which is located on the right console. Later models of the F-100D
have an external canopy jettison handle located on the left side of the
aircraft.

Operation
As shown in figure 8-3, raising the handgrips to the full up position
fires a mechanical initiator. Gas pressure from this initiator actuates
the piston in the exactor, which in turn fires the canopy remover.
Squeezing the trigger on either seat handle causes one or both of
the mechanical initiators to fire; gas pressure then fires the catapult.
As the seat moves up and out of the aircraft, the mechanical-delay initi­
ator is fired, releasing the lap belt and shoulder harness. The mechan­
ical-delay initiator also fires the explosive charge in the rotary actu­
ator, resulting in separation of man and seat.
Normal activation does not fire every item in the system; for example:
(1) jettisoning the canopy normally from inside the aircraft will
leave the external initiator in the live condition.
(2) external jettisoning of the canopy will leave the internal
initiator in the live condition.
(3) squeezing the trigger on one side of the seat will leave the
initiator on the other side of the seat unfired.
Before you attempt any action on the aircraft you should determine
which method was used to activate the system.
Canopy Removal
Since the aircraft canopy must be removed before you can gain
entrance to the cockpit, you should be familiar with the three means
of canopy removal. These are illustrated in figure 1 and described
below.
ELECTROMECHANICAL-NORMAL REMOVAL. The canopy can be removed by
electro-mechanical-normal means by using the push-type switches located
on either side of the aircraft below the windshield. The aircraft battery
or an external power source must be available.
MANUAL (EMERGENCY REUSASE). The aircraft canopy can be manually
released by using either of the two external emergency release handles,
located on the right and left front of the canopy on C/D aircraft and
on the right and left rear of the canopy on the F-100F aircraft.
PNEUMATIC JETTISON. Pneumatic jettison can be accomplished ex­
ternally by using a mechanical initiator and a 6-foot lanyard with a
handle.
8-8
Raising the handgrips to full up position causes the handgrip
striker to actuate the canopy linkage that pulls the sear pin
from the canopy initiator, firing the initiator.
A R M O R PLATE

-C A N O P Y REM OVER
Gas pressure from the initiator actuates the piston in the

The F-IOOF is essentially the same as the F-100D except that the
following components have been added:
1. A mechanical initiator in each cockpit for firing the canopy
remover.
2.
Another seat fully equipped for ejection.
3. Four gas-actuated initiators - these initiators enable the man
in the front seat to fire the rear seat catapult and provide a delay for
the firing of the forward seat.
Safing Procedures for the F-100 Aircraft
Following is a checklist of safing procedures for the F100 aircraft.
Because of the variable conditions in which the aircraft may be found,
it may not be possible to safe the egress system in the exact order in
which these procedures are listed. Refer to figure 2 and table 1 as you
study the procedures. Table 1 is located at the back of this study guide.
1. If the canr"v>r ^ present, gain access to the cockpit by using one
of the three me'vnoas previously mentioned.
2.
Disconnect the rocket catapult quick-disconnect.
3.
Check the positions of the handgrips.
NOTE
The handgrips are intercon­
nected and move simultaneously.
U. Install the ground safety pin(s) in the right handgrip(s) of the
8eat(s) and through the canopy emergency jettison handle(s) on the right
consoleCs).
CAUTION
Insure that the handgrips are
fully down and locked before
inserting the ground safety pins
5. Remove the components, insuring that maintenance safety pins are
installed in each mechanical device and that plugs or protective caps are
installed on gas-fired devices.
8-10
F-105D AIRCRAFT
The F-105D uses esentlally the same system as the F-100, with a
few exceptions. It incorporates a thruster for unlocking the canopy and
an explosive actuator for removing the canopy. Unlike the F-100, the
canopy jettison handle on the F-105D is located on the left console and
has an initiator immediately below the handle. If the egress system is
activated normally this initiator will be found in a live condition.
The seat operation is basically the same as that of the F-100D, again
with a few exceptions.
Operation
Raising the leg braces arms the ejection system. Squeezing the
triggers fires the canopy/delay initiators. The canopy initiator actu­
ates the thruster to unlock the canopy. Pressure from the thruster then
goes on to actuate the canbpy remover. The canopy is jettisoned. The
delay initiator produces gas pressure to actuate the RAPEC and it ejects
the seat. Seat travel fires another delay intiator which actuates the
lap belt, the rotary actuator, the personnel force-deployed parachute,
and the drogue gun to deploy the seat retardation parachute. Refer to
figures 8-4, 8-5, and 8-6.
This aircraft is basically the same as the F-105D model but in
addition to the duplication of devices for the extra seat, it uses a
delay initiator which delays jettison of the rear canopy during ground
jettison.
NOTE: On aircraft modified by T.O. lF-105F-5^2, the aft seat contains
an explosive powered inertia reel used to restrain the occupant on the
ejection position when ejection is initiated from the forward cockpit.
Safing Procedures for the F-105 Aircraft
Following are the safing procedures for the F-105 aircraft (refer
to figure 5 and table 2 as we discuss the safing procedures). Table 2
is located at the back of this study guide.
1.
Insert the safety pin in the canopy ground emergency initiator.
2.
Disconnect all pressure line quick-disconnect devices by pulling.
3. If the leg braces are down, install safety pins in the right-hand
side of the ejection seat and through the auxiliary canopy jettison handle
in the left console.
4. Install ground safety pins if applicable, and remove all com­
ponents.

AIRCRAFT

This
rtems
This aircraft utilizes the Martin-Baker MK H-5 ejection system. This
system, although quite similar to other egress systems, has some distinctly
different features. It is actuated much the same as other systems by use
of a mechanical linkage to- release a cocked firing pin; however, the cata­
pult has one primary and two secondary explosive charges. This system also
uses a drogue gun to open the primary parachute. The drogue gun, because
of its design and explosive content, is extremely hazardous. Unlike the
other devices, it fires a 15-ounce projectile out of the barrel like a
rifle. The projectile, of c o u r s e , represents a hazard to personnel and
equipment. Refer to Figures 8-8 and 8-9 as you study the ejection sequence
which follows.
1. Either the face curtain handle or the secondary ejection handle
is pulled.
2. The mechanical initiator is fired; this subsequently jettisons
the canopy. Also gas pressure from this initiator fires a gas generator
that pulls the pilot to the ejection position.
3.
Continued pull of the face curtain fires the ejection gun.
k.
As the seat moves upward it reaches the end of a cable lanyard
that fires the mechanically initiated rocket pack that sustains the seats
upward motion.
Refer to figure 8-9.
5. The drogue gun fires 1 second after ejection to deploy the con­
troller drogue and stabilizer drogue.
6. The time release mechanism operates and releases restraint
harness, leg restraint cords and eventually leads to deployment of the
personnel parachute.
7. If the time release mechanism fails, release of the occupant
from the seat is accomplished by the use of the emergency release handle
which releases the restraint harness and fires the guillotine cartridge.
The F-k series aircraft have a system whereby either pilot can eject
himself or both seatB. This accomplished by a select valve in the aft
cockpit (see figure 8-10) and by adding two each sequence actuators,
initiators, and boosters.

Canopy Removal
The canopy on the F-Uc aircraft may be opened several different ways.
Since BOD personnel are concerned with entry into the cockpit, the ex­
ternal means of entry are as follows (refer to figure 8-11 as you read):
1.
By pressing the forward/aft canopy open/close push buttons.
2.
By use of the canopy external jettison handle.
3.
Ifr use of the forward/aft external manual unlock handles.
NOTE
Two mechanical initiators used
for external canopy jettison for
F-U series aircraft sure located
inside each cockpit on the left­
side of the rear canted bulkhead.
Safing Procedures for the F-1»0 Aircraft
Following are the safing procedures for the F-1»C aircraft. However,
due to the variable conditions in which the aircraft may be found, it may
not be possible +~ ~afe the system in the exact order in which these procedures arc xisued. liefer to figure 8-12 as you study the procedures.
1. If the canopy is present, gain access to the cockpit by using
one of the methods previously mentioned.
2.
Replace the safety pin in the drogue gun and detach the trip
rod.
3. Place safety pins in the face curtain, ejection gun, guillotine
firing mechanism, initiators, and rocket pack.
U. Remove the components, insuring that maintenance safety pins
are installed in each item. Figure 8-12 shows the safety pins installed
and table 3 lists the total number of components. The table is located
at the back of the SSG.
NOTE
If a safety pin cannot be used
on the ejection gun, the firing
head may be removed.

AIRCRAFT
The A-IE aircraft uses a new concept in personnel ejection. Rather
than actually ejecting a man and seat, the A-IE incorporates a rocket to
extract only the man; the seat remains in the aircraft. This egress
system is comprised of cartridge-actuated devices that have a different
nomenclature than those with which most EOD personnel are familiar; there­
fore, they will be discussed in dstail in this study guide. At the present
time the A-IE is the only aircraft to incorporate the new system; however,
in the near future it may be found in the A-26, T-28, and 0V-10 aircraft.
The A-IE escape system is illustrated in figure 8-13.
Extraction Rocket
The nozzles of this extraction rocket are on the front and the
rocket pulls the man from the seat by employing a pendant line attached
to each parachute riser. The rocket is internally launched from the
aircraft by use of a launcher cartridge. The rocket itself is ignited
when pull is exerted on the pendant line; When the rocket has expended
95 percent of its energy, a guillotine type of cutter is activated, thus
severing the pendant line and allowing the rocket to carry itself away
from the vicinity of the man.
Pendant Line
The p-auant. llr«. is a
cord which connects the man to his ex­
traction rocket and which is disconnected prior to parachute opening.
Messenger Cord
Messenger cord is a mild detonating fuze and a contained detonating
fuze. The cord contains 2 grams per foot of PETN and is used to initiate
cartridges for the rocket launcher, rocket erector, and canopy removal
system. A lead styphnate booster is built into each end of the cord.
The cord may be used within a nylon sheath (contained detonating fuze)
or without the nylon sheath
Manifolds (initiators)
Manifolds are nothing more than mechanical initiators. Unlike
normal initiators, which produce gas pressure, the manifold initiators
used in this system fire the detonating cord.
Pendant Disconnect Activator
The pendant disconnect activator is housed in the para-pack. It
contains three cartridges; one of these is used to expel a 1-pound
drogue slug for deployment of the parachute and two are used to pro­
vide pressure to operate the pendant disconnect.

Timer
The timer, which contains a cartridge, is contained within the
parachute and is activated by the mechanical pull of a flexible lanyard.
A barometric device is contained within the timer and blocks operation
above 15,000 feet. Gas produced from the cartridge in the timer is
used to fire the cartridges in the pendant disconnect. The timer is
illustrated in figure 8-13 and table 4. Table 4 is located at the back
of this SG.
Ejection Sequence
Following is the ejection sequence for the A-1E egress system.
Refer to figure 8-13 as you study this sequence. The following sections
are begun when the handle, located in the center of the seat is pulled.
1.
The inertia reel is locked.
2.
The seat is allowed to fold downward after upward motion.
3.
Two rail-mounted ballistic manifolds are initiated.
4. As shown in figure 8-14, the canopy removal system is initiated
and the launcher cartridge is fired.
5. The extraction rocket is launched and ignites after full stretch
of the pendant line.
6.
The occupant is pulled from the seat through the canopy opening.
7. The parachute is deployed after the timer cartridge fires in the
para-pack.
NOTE
A secondary escape handle ,is
located on the right side ;of
the seat pan. If a crew member
decides to bail out rather than
eject, the actuation of this
handle allows separation from
seat and rocket, allowing con­
ventional procedures to be used.
Emergency Entrance
Entrance to the pilot's cockpit may be accomplished by turning the
control knob to the open position and sliding the canopy to the rear
(see figure 8-15).

Aircraft Guns and Pods and Miscellaneous Hazards
OBJECTIVES: The purpose of this text is to supply knowledge to the
EOD technician for identification, basic operation, clearing and safing
of aircraft guns and pods. Also, to familiarize them with miscellaneous
hazardous components that could be encountered on the F-100, F-105,
F-4, and A-l series aircraft.
INTRODUCTION! Aircraft guns and pods have always presented a problem
to the EOD technicians who have had to walk around or work on them in an
aircraft crash. Also, many instances have occurred where EOD personnel
were the only people capable or available to safe the gunnery systems on a
transient aircraft. These are just two of the reasons why they are dis­
cussed. Another problem to the EOD technician is the location of miscella­
neous hazards that are not part of major systems. These hazards may be
explosive or no-explosive. The F-100, F-105, F-4, and A-l series aircraft
are the only ones discussed because these are the workhorses in SEA and
a good working knowledge of these aircraft will help in handling all type
aircraft incidents. There is no specific or set pattern for disposal or
destruction of aircraft guns and gun pods and possible approaches to disposal/
destruction will be discussed for each system covered in the classroom.
M3 CALIBER .50 MACHINE GUN

M3 AND M24 20-MM AUTOMATIC GUNS
1.
Use of Guns
Both the M3 and the M24 automatic guns are used in Southeast Asia on
the A-l series aircraft— the M3 on the A-1E and the M24 on the A-1H and J
(see figure 9-7). They could be interchanged, however, because they are
identical in appearance and differ only in the method used to fire their
ammunition. Safing and clearing procedures will also be the same for
both types. Figure 9-4 shows the M3 20-mm automatic gun.
9-5
Figure 9-4.
2.
M3 20-nun Automatic Gun without Feeder Mechanism
Ammunition
The M3 20-mm automatic gun uses percussion-primed ammunition whereas
the M24 automatic gun uses 20-mm electric-primed ammunition.
CAUTION
Some types of 20-mm ammunition currently used in the M3
20-mm automatic gun have a fuze that is "nonbore safe."
This feature makes this ammunition more sensitive to
rough handling.
3.
Safety Precautions
The following safety precautions apply to the M3 and M24 20-mm automatic
guns.
o
Never walk in front of the gun until you are sure it is safe and clear.
o
Never put your hands into the receiver or the feeder mechanism.
o
Do not cut or disconnect the hose to the gun charger until the system
has been bled. This system is pressurized to 1500 psi.
o
Do not remove the trigger mechanism until the bolt has been blocked.
9-6
4.
Safing Procedures
Safing of the M3 20-tnm cannon is accomplished by disconnecting the
electrical lead from the electric trigger mechanism located at the rear of
the gun on the bottom.
5.
Clearing Procedures
Clearing of the M3 20-ram cannon is accomplished by performing the
following steps:
a. If the bolt is in the retracted position, install the gun-clearing
block (see figure 9-5) or suitable substitute to prevent the bolt from moving
forward to the battery position.
WARNING
The gun clearing block will allow the bolt
to come forward to within 1/2 inch of battery
position and prevent the gun from firing.
Fingers will be crushed if they are in the
receiver assembly and the bolt is accidentally
released. Removal of the trigger mechanism
will allow the bolt to come forward.
b. Remove the ammunition from the feeder mechanism by pushing in and
turning the 5/8-inch hex nut on the end of the feeder toward the rear of the
gun. Turn this nut in the direction opposite to that which feeds ammunition
to the gun.
WARNING
The feeder mechanism is spring wound. If it is
not completely de-torqued, it could cause severe
injury to fingers or hands. KEEP YOUR HANDS OUT
OF THE FEEDER.
c.
Disconnect the ammunition and link chutes from the feeder mechan­
ism.
d. Disconnect torque lever (from lower part of feeder) by pushing down
and prying out with a large screwdriver.
e. Lift up on the feeder release handle, grasp feeder, and lift it out

Major Components of the M39A2 20-mm Automatic Gun
M61 AND GAU-4 20-MM AUTOMATIC GUNS
1.
The M61 and GAU-4 automatic guns are the latest concept in aircraft,
rapid-fire automatic weapons. These guns employ the gatling principle of
operation. The M61 is used in SEA on F-4E, F-105, C-130, and C-119 aircraft,
and in the SUU-16 gun pod. The GAU-4 gun is used in the SUU-23 gun pod.
The EOD procedures for both guns are identical.
2.
Ammunition
Both the M61 and the GAU-4 guns use 20-mm electric-primed ammunition.
3.
Safety Precautions
The following safety precautions pertain to the M61 and GAU-4 guns:
o
Never walk in front of the gun until you are sure it is safe and
clear.
o
Be sure the clearing sector cam remains engaged at all times while
working around the aircraft.
o
Never put hands into the barrels until you are sure what you are
doing.
4.
Safing Procedures
Safing of the M61 gun is accomplished by disconnecting the electrical
lead on the top half of the receiver section (see figure 9-11).
5.
Clearing Procedures
To clear the M61 gun, follow these steps:
a. Push in and secure the clearing sector cam. This cam is located
on the bottom of the receiver near the back plate of the gun (see figure 9-12)
WARNING
In most installations this gun is driven by an
electric drive motor. Be sure that armament
switches are OFF or electrical power to the
motor is disconnected before putting hands
into barrels.
b. Rotate the barrels in a clockwise direction so that all six barrels
make one complete revolution. This will track all bolts to the rear and,
as long as the clearing sector cam is down, will prevent a h f rounds from the
battery position.

MISCELLANEOUS AIRCRAFT HAZARDS
1.
General
a. Battery Systems. Aircraft batteries supply power to function most
electro-explosive devices and should be disconnected If possible. Aircraft
switches may perform the same function, but the condition of electrical
wiring in an aircraft crash cannot be determined, so the switches may not
perform the function. Disconnecting at the battery is a positive means
of breaking power to the aircraft electrical systems. Most aircraft batteries
have a quick disconnect at their terminals. Turning the wheel on this dis­
connect counterclockwise will disconnect it.
WARNING
Battery fumes are highly explosive. Keep open
flames and spark producing devices away from
batteries.
The batteries contain acid which may cause
burns to the skin. If spilled on the body,
wash affected areas thoroughly with water
and then apply bicarbonate of soda, if
available, until medical treatment can
be obtained.
Spilled fuel/fuel vapor may be present in
the vicinity of crashed aircraft. Common
sense and good judgment should be exercised
when disconnecting the battery or elec­
trical leads under these conditions to
avoid arcing of the battery voltage.
b. Guns. Since guns have already been covered in the beginning of
this chapter, this section deals only with the location, number, and type
of guns by aircraft.
c. Ammunition. This section deals with location, type and amount of
ammunition by aircraft. Most ammunition found in SEA is HEI and should be
handled with care. 20-mm ammunition can be electric or percussion fired and
the fuzing can be "Bore" or "Non-Bore" safe depending on the aircraft in
which it is used.
WARNING
20-mm electrically primed ammunition is an electro­
explosive device and should be handled accordingly.
Personnel will ground themselves to the aircraft
before handling 20-mm ammunition. It may also fire
by percussion. 2 0 - m m HEI ammunition with the PD
fuze 175 is relatively "Non-Bore Safe" and should
be handled with extreme care.
9-27
d.
Engine starter cartridges. Aircraft carry both operational (located
in thestarter breech) and spares. They do not have to be present, but the
locations should be checked to be sure. Spare cartridges should still be
packaged in their original containers. If a cartridge is not in its container,
be sure it is shunted out before handling.
(figure 9-23)
WARNING
Engine starter cartridges are electro-explosive
devices and should be protected from electro­
magnetic transmitting systems.
Be sure all power is disconnected from the
aircraft before removing the operational
cartridge from the engine starter breech.
Personnel should ground themselves to the
aircraft before removing starter cartridges
and never let the cartridge contacts come in
contact with the aircraft skin.

INTRODUCTION
In this student text we willdiscuss aircraft suspension and release
systems (bomb racks and pylons) and components of the aircraft that may
be pertinent to a safe EOD operation. Reports from SEA have continually
indicated a need for this information. Again, keep in mind that we are
interested in the items being discussed from an EOD viewpoint— how these
items may affect us during the course of our operations. The aircraft
that we will cover are:
o
F-100 (D and F models)
o
F-105 (D and F models)
o
F-4 (C, D and E models)
o
A- j. (E model)
TERMINOLOGY
General
Before we can start on the individual aircraft we must clarify the
terminology associated with aircraft suspension and release systems
These definitions will apply to all the aircraft we will discuss. Be
sure they are clear in your mind.
BOMB RACK (BR). A bomb rack can best be described as an electro­
mechanical device designed to carry, arm, and release airmunitions. These
racks will normally have 14-inch, 30-inch, or a combination of both 14-inch
and 30-inch hook spacing to accommodate the suspension lugs in US munitions.
Usually a bomb rack that has only 14-inch hooks is limited to airmunicions
that weigh 1000 pounds or less, and the 30-inch hooks accommodate airmunitions which weigh in excess of 1000 pounds.
In nearly every case
these racks will have a provision for a mechanical safety pin which will
physically prevent the rack hooks from opening and some means of manually
releasing the hooks to remove the airmunitions from the aircraft when it
is on the ground. This is the means of release that is of prime concern
to use in EOD.
BOMB EJECTION RACK (BER). A bomb ejection rack is basically the
same as the original bomb rack; however, one important item has been
added. With the advent or supersonic aircraft, it was discovered that
externally carried stores were tending to "hang" under the aircraft after
the hooks were released. This action resulted in a hazard to the air­
craft when the bombs were fuzed with certain fuzes. Explosive cartridges
are now incorporated into the bomb rack (see figure 1 0 - 1 ) to forcibly eject
the store away from the aircraft--hence the term bomb ejection rack.
The addition of these explosive cartridges constitute a definite hazard
to personnel working on the aircraft which use the ejection type racks.
Most of these ejection racks must have hot gas exhaust ports (see figure
1 0 - 1 ) which would cause serious personal injury if you should be in the area
of the port when the cartridge fires. Both the standard bomb rack and
the BER will normally have provisions for a ground safety pin and a method
of manual release (see figure 1 0 - 1 ).
NOTE
pressure generated by these
cartridges in some cases performs
more than just ejection of the store;
however, to us this is inconsequential.
It is sufficient to know that the
bomb rack contains explosive cartridges
which eject the store; exhausts hot gases
when functioned; and must be safed prior
to working on a suspension system which
contains them.
PYLONS AND ADAPTERS. This nomenclature is at best vague and is
applied differently to individual aircraft. Even the aircraft manufact­
urers do not have a standard nomenclature for them. Usually a "pylon"
is considered to be a support assembly, aerodynamically configured to
an aircraft, capable of carrying some form of external store such as
bombs, fuel tanks, rockets, or missiles. To better illustrate the
difficulty when defining these items, let us look at the four aircraft
to be discussed in this study guide as examples:
1 0 -2
1 . The F-100 uses the term "pylon" for all of its external suspen­
sion mechanisms.
2. The F-105 uses the term "pylon" for all its bomb racks, but uses
"adapter" for one of its missile launchers and "launcher" for another
missile adapter.
3 . The F-U uses the term "pylon" for all of its bomb racks and
"launcher" for all of its rocket and missile launchers.
U.
racks.
The A-1E refers to all of its external suspension system as bomb
From this we can see that by technical standards we are incorrect
by calling all external stores suspension mechanisms "pylons", but it
is only a technicality and regardless of what name we apply to it we
need only be correct in knowing:
•
How to electrically and mechanically safe these mechanisms.
•
How to explosively safe them.
•
How to remove the airmunitions which is loaded on them.
In this student text we will use the nomenclature given in the applicable
AFTOs.
ADAPTER. This term is usually applied to a mechanism that is used
to change a particular suspension system from its original capability
to a different one.
NOTE
For U.S. Navy suspension systems,
the term "adapter" is used exten­
sively; whereas on USAF suspension
systems, the term is ^infrequently
used.
LAUNCHERS. This term "launcher" is used when a suspension system
is used to carry and launch aircraft rockets or missiles.
BOMB EJECTION CARTRIDGES. These cartridges come in many different
types and the number designations are numerous. The fact that these
cartridges are electrically primed and contain gas-producing explosives
is all that we in EOD need remember; therefore,an Air Force ARD Uh6-1
cartridge and a Navy MK-2 cartridge are the same to us. Some models of
these cartridges are used to Jettison missiles (Navy MK-17 for AGM-12/B
and small stores; Air Force ARD 8 6 3 -I in the SUU-lh dispenser). It is
very Important for us to remember that bomb ejection cartridges are
10-3
present and that they must be removed before work can be done safely on
any mechanism which contains them.
MULTIPLE EJECTOR RACK (MER). This may be a new term to you, but we
will find it is a very simple item. A MER consists of six individual
1^-inch bomb ejection racks. These six racks sure bolted to a strongback
(see figure 1 0 - 2 ), giving a single external airmunition station the capa­
bility of carrying tip to six munitions. Each individual BER bolted to
the MER has all the basic components of a 1 ^-inch BER, the basic difference
being that these racks use only one ejection cartridge per rack instead
of the usual two (see figure 10-3). The manual release for the individual
rack is a lever located on the front of the rack (see figure 10-3). Pulling
forward on this lever will open both of the bomb hooks simultaneously.
Each rack has a provision for two mechanical safing pins (see figure 10-3)
and the installation of a pin in either hole will effectively lock the
hooks of the rack. The strongback has a provision for lugs to load it
into the 3 0 -inch hooks of a bomb rack, or it can be bolted to a bomb
pylon adapter. On the rear end of the strongback there is a selector
switch to be used to select various loads that can be carried and to
provide for inserting an electrical ground safety pin (see figure 1 0 - 2 ).
This pin cuts the circuit to the bomb ejection cartridges when it is
installed. Also there is an electrical connection between the MER and
the aircraft pylon which, when disconnected, will electrically safe the
entire MER.
NOTE
The A-IE aircraft uses a slightly different
version of the MER which will be discussed
in the portion of this SSG that deals with
the A-IE aircraft.
TRIPLE EJECTION RACK (TER). This type of rack is a shorter version
of the MER. It will carry a total of three items, and the BERs and other
components are the same as the MER.
SHACKLES. These mechanisms originated in WW II and are used in
bomb-bay applications. The shackle is basically a 1^- or 30-inch rack
which is attached to the bomb and the assembly is then attached to the
appropriate stations in the bomb bay. The shackle or "rack" requires a
separate mechanism for normal release. This mechanism is known as the A-5
release mechanism. This mechanism, although separate from the shackle,
is used to release the hooks on the shackle either electrically from the
cockpit or manually in the bomb bay. The store can be released from its
station in one of three ways:
1. Rotating the trip slot on the A-5 release mechanism by UBe of
a standard screwdriver.
10-4
2.
Activating the release lever on the shackle.
3. Removing both the munition and the shackle from the carrying
station as a unit.
NOTE
At present only two aircraft have
this system in SEA--the B-52 and the
A-26.
Abbreviations
To be sure that you understand the abbreviations used in this study
guide, a list of those most frequently encountered follows:
BR— bomb rack
BER— bomb ejection rack
MER— multiple ejection rack
TER--triple ejection rack
MAU— munlti'
ixiliary unit (This term is rapidly replacing the
"Aero" and "MK" on the newer aircraft. It is normally applied to bomb
racks.)
LAU--launch auxiliary unit. (This term refers to rocket and missile
launchers. Like the term "MAU" it is replacing older launch unit term­
inology. Keeping all of these definitions and abbreviations in mind, we
will now discuss the individual aircraft.
F-100 (D AND F MODELS) AIRCRAFT
General
The F-100D aircraft is a single-seat, single-engine, tactical
fighter which has seven stations for carrying airmunitions externally
(see figure 10-4. The stations which carry munitions on the F-100
aircraft are designated (see table 1):
Outboard wing (L & R)
Intermediate wing (L & R)
Inboard wing (L & R)
Centerline
10-5
Outboard Wing Station
This station uses the type III pylon (see figure 10-5. The pylon
houses a lU-inch BER which has provisions for a mechanical safety pin
and a screwdriver slot (large common tip) for external manual release.
Using the screwdriver, turn it counterclockwise in the slot and both
hooks will open.
ROTE
When the ground safety pin is
installed, the hooks cannot be
opened. This is true for all
bomb racks.
The bomb ejection rack used in the type III pylon has a provision
for two bomb ejection cartridges (see figure 10-5). An additional two
cartridges are installed in the pylon for emergency jettison of the pylon
and store.
Intermediate Wing Station
This station can be fitted with one of two pylons--the type III
which is the same as the one used on the outboard station, or the type
VIII. The type vTT"
(see figure 10-6) houses a 30-inch BER. An
additional hook spaced 2 0 inches apart is incorporated and is used to
carry special items. This hook is ganged in with the two 30-inch hooks.
The BER used in the type VIII pylon is the same in all other respects
as the BER used in the type III pylon. It has provisions for a ground
safety pin, a manual release, and two ejection cartridges. This pylon
can also be jettisoned in a emergency; therefore, two additional ejection
cartridges are installed for this purpose (see figure 1 0 -6 ).

discuss each of these pylons.
We will now
TYPE I PYLON. This pylon houses the same 1^-inch BER as the type
pylon. The only difference between the type I and III pylons is the
aluminium fairing which is shaped to fit the contour of the wing. All
TII
1 0 -6
components of the type I pylon that are of concern to EOD personnel are
the same as those on the type III pylon (see figure 10-5).
TYPE IX PYLON. This pylon (see figure 10-7) is used to carry and
launch the AIM-9 (Sidewinder) missile and is configured to carry two of
these missiles. Due to the way in which AIM-9s are jettisoned (launched
unguided) there are only two explosive cartridges in the pylon, and these
are used for pylon jettison (see figure 10-7). The pylon has provisions
for two electrical safing pins (one per missile) and two mechanical release
handles (one per missile). Rotating the release handle will unlock the
missile from the rail and the missile can be unloaded by sliding it for­
ward.
TYPE X PYLON. This pylon is used to carry and launch the AGM-12/B
(Bullpup) and the AGM-45 (Shrike) missiles. This pylon is being phased
out; however, it could be encountered in the SEA theater. The type X
pylon will contain three explosive cartridges. Two of these cartridges
are used to jettison the pylon and the third, located in the bottom rear
of the pylon, is used to jettison the missile. The pylon requires one
electrical safing pin and the missile is unloaded by operating the re­
lease handle and sliding the missile forward and off the launch shoes.
Centerline Station
At present the only airmunition pylon that could be used on this
stationis th ^ i.ype vil (see figure 10-8). The type VII pylon is designed
to carry special weapons. Reports from SEA indicate that airmunitions
have been loaded on the F-100 centerline station so we will discuss the
type VII briefly. The type VII pylon houses a 30-inch bomb rack. The
rack has no provision for ejection, but it uses the same type of ground
safety pin and mechanical release as the other bomb racks on the F-100
aircraft. Although the type VII pylon does not have an ejection rack,
it has a provision for two explosive cartridges for jettison of the pylon
(see figure 1 0 - 8 ).
CAUTION
It is known that some loading configurations
do not require the use of these cartridges,
but as EOD personnel we must assume that
they are present until we physically check
the cartridge holders. We are interested
only in the number of cartridges that
could be present.

F-105 (D AND F MODEL) AIRCRAFT
The F105 aircraft is a tactical fighter-bomber which has five external
stations for carrying munitions.
NOTE
The F-105 series aircraft are equipped with
an internal bomb-bay system; however, it is
not used for conventional munitions, and it
will not be covered in this course.
The five external airmunition stations we will discuss are (see figure 10-9
and table II):
1.
Outboard wing (R & L)
2.
Inboard wing (R & L)
3.
Centerline fuselage (bomb-bay doors closed)
Outboard Wing Station
This station can have one of two type pylons installed— the 14-inch
Universal (RAC) BER of the AERO 3/B (AIM-9) missile adapter.
The 14-inch Universal (see figure 10-10). This pylon is quite unique
and could cause p -w - difficulty to personnel working on it because it
does not conform to standards associated with other racks. The 14-inch
BER is housed in the outboard pylon and will have two cartridges for the
bomb rack and two cartridges for the emergency jettison of the pylon.
Instead of a mechanical safety pin this rack requires two mechanical
safety blocks (one for each hook linkage) to prevent the hooks from
opening. To manually release the store which it carries, it is necessary
to rotate each hook linkage separately because they are not ganged to­
gether. The hooks are rotated by using a 7/16-inch wrench on the stud
located on each hook linkage (see figure 10-10). To gain access to both the
explosive cartridge and the manual release studs, it is necessary to
remove an electrical safing plate (see figure 1 0 -1 0 ) and undo the dzus
fasteners which secure the access panel. Removing the red safing plate
will electrically safe the circuits to the explosive cartridges. With
the access panel open, the four explosive cartridges can be removed and
the release mechanism can be operated or the safety blocks can be installed.
CAUTION
Since the bomb hooks are not ganged together,
care must be taken to ensure that the munition
which is being unloaded does not bind when one
hook is released.
The other pylon that can be used on this station is the AERO 3/B (AIM-9)
missile adapter (see figure 10-11). This adapter will accommodate two AIM-9
(Sidewinder) missiles. As mentioned previously these missiles are jettisoned
by launching them unguided. No explosive cartridges, therefore, are neces­
sary for this purpose. When installed on the aircraft the pylon itself
10-9
cannot be jettisoned and, therefore, with the AERO 3/B adapter there will be no
hazard from explosive cartridges (see table II).
Each missile launch rail
on the pylon has provisions for an electrical
safing pin (see figure 1 0 - 1 1 ),apd the missiles are removed by inserting a
3/8-inch alien key in the nose section release hole (see figure 10-11) to
disconnect the umbilical cord.
Then, using the same alien key in the detent
release hole (see figure 1 0 -1 1 ) the fissile can be released by sliding it off
the rail.
Inboard Wing Station
One of three different pylons may be used on this station. These pylons
are the inboard universal pylon, the inboard multiweapons-pylon, and the GAM-83
adapter.
1. The inboard universal pylon houses a 14-inch or a 30-inch bomb
ejection rack. These are individual racks, but both of them are identical
with the exception of the hook spacing (see figure 10-12). The bomb racks
have a provision for two ejection cartridges and the pylon can be jettisoned
by two cartridges used for that purpose. The pylon has a provision for two
safety pins— one for the hooks (see figure 1 0 - 1 2 ), which is a mechanical lock
and one for the cartridge circuits which is electrical (see figure 10-12). The
stores are released from the rack by placing a wrench on the forward hook sear
stud (see figure 10-12) and rotating it. These hooks are ganged together so
they will both open when the stud is rotated. Access to both the cartridges
and manual release stud is by the saem manner as for the outboard universal
pylon, except there is no ^ ' ’-'trical safety switch plate to remove.
2. Inboard multiweapons pylon. This pylon houses a 14- or 30-inch
BER. The pylon has four explosive cartridges, two for the rack and two
for the pylon (see figure 10-13). This pylon uses two safety pins— one
electrical for the cartridges and one mechanical for the hooks (see fig­
ure 10-13). Manual release of the stores which are carried can be accomplished
by rotating the hex stud on the exterior of the pylon skin (see figure 10-13).
NOTE
There is no hinged access panel on the multi­
weapon inboard pylon.
3.
GAM-83 adapter. This adapter (pylon) is used to suspend and launch
either the AGM-12/B (Bullpup) or the AGM-45 (Shrike) missiles. The pylon
cannot be jettisoned, but it contains one explosive cartridge for jettisoning
the missile (see figure 10-14). Only for explosive cartridge will be present
in this pylon. A provision for one electrical safing pin for the missile launch
nad jettison circuits is provided, and the missile is manually released from
the launcher by pulling out and lifting up on the manual release handle and
sliding the missile forward and off the launch shoes (see figure 10-14).
1 0 -1 0
Centerline Fuselage Station (External Only)
This station can be adapted to accept one of three pylons: the
fuselage centerline pylon, the fuselage multiple ejector rack (MER)
pylon, and the fuselage multiple weapons rack pylon. These pylons are
explained below:
1. Fuselage centerline pylon. This pylon (see figure 10-15) is used
to carry only a fuel tank. The tank is bolted to the pylon, and it is hooked
externally to the bomb-bay doors as a unit. There are only two cartridges
used in this pylon (see figure 10-15). When the cartridges are functioned
they will jettison the pylon and the fuel tank as a unit. This pylon has
an electromechanical safing pin which when installed breaks the circuit
to the jettison cartridges and prevents rotation of the release mechanisms
(see figure 10-15). To manually release this pylon and tank assembly from
the aircraft, open the access doors at each sway brace, pull out each
linkage, and rotate each linkage counterclockwise (see figure 10-15).
NOTE
This procedure is required at each sway
brace as the attachment assembly hooks
are not ganged together.
2. Fuselage multi-ejector rack pylon. This pylon is similar to the
one used for the fuel tank because the MER is bolted to the pylon and the
pylon hooks to the bomb-bay doors, and, if jettisoned, the pylon and MER
are jettisons.'
a unit. The pylon contains two explosive cartridges
(see figure 10-16) and uses an electrical safing pin to safe the jettison
circuit. The manual release safety consists of a nut and bolt used to
secure the manual release handlt to the skin of the pylon (see figure 10-16).
Removing this nut and bolt and pulling forward on the release handle will
release the pylon and the MER as a unit.
3. Fuselage multi-weapon ejector rack (see figure 10-17). This pylon
houses a 14-inch and 30-inch BER (MAU-12/B), and it can be used to carry
a single airmunition or a MER. When a MER is carried on this pylon, it
will be held on the 30-inch lugs of the BER instead of being bolted to
the pylon. Since this pylon contains a BER, it will have a provision for
four cartridges— all located approximately in the center of the pylon
(see figure 10-17). The two cartridge holders used for pylon jettison have
a special lock mechanism that must be rotated before the cartridge holders
can be removed. This pylon uses two safety pins: one electrical safety
pin or the cartridges and one mechanical safety pin for the BER. The
manual release for the hooks of the BER is a 3/8-inch swuare drive insert
and the pylon is released manually in the same manner as the MER pylon.

F-4 (C, D, AND E MODELS) AIRCRAFT
The F-4 is a two-place, twin-engine tactical fighter-bomber (see
figure 10-18). All models of the F-4 aircraft have nine stations for carrying
airmunitions externally (see figure 10-18 and table III). These stations
are listed below:
1.
Centerline
2.
Fuselage missile stations (4 each)
3.
Inboard wing station (R & L)
4.
Outboard wing station (R & L)
We will discuss the suspension systems used on each of these stations.
CENTERLINE STATION. This station contains an AERO 27/A, 14- and 30inch BER (see figure 10-19). The rack is built into the fuselage centerline
and cannot be jettisoned; therefore, there are no explosive cartridges
present for this purpose, but there will be two cartridges for stores
ejection. These cartridges are contained in a breech assembly on the top
of the bomb rack (see figure 10-19). The breech assembly can be rotated
90° to facilitate cartridge removal. The rack is manually safed by installing
a safety pin (see figure 10-19), and the stores are released by rotating the
manual release stud (see figure 10-19). Access to the safety pin hole,
cartridge breech •
’M manual release stud is gained through a large access
panel on the siae or the bom,b ejection rack. When some airmunitions are
carried on this station an adapter is used (see figure 10-19). This adapter
contains no explosive items and is loaded into the 30-inch hooks of the
AERO 27/A.
FUSELAGE MISSILE STATIONS. These four stations are recessed into
the skin of the bottom out edge of the fuselage— two stations forward and
stations aft. Each station is fitted with an AERO 7/A missile launcher
which is designed to carry and launch the AIM-7 (Sparrow) missiles (see
figure 10-20). When the missiles are loaded on these stations the front
and rear in of each missile extend into the aircraft interior. To get the
missile clear of the fuselage prior to launch, two explosive cartridges are
used (see figure 10-20). Since the AERO 7/A launchers are an integral part
of the airframe, they are not jettisoned; therefore, there are no cartridges
present for this purpose. Each launcher has a provision for an electro­
mechanical safing pin and a hex stud for manual release (see figure 10-20).
10-13
Access to the cartridge breech, the safing pin hole, and the manual release
stud is through a small panel on the side of each missile launcher.
INBOARD WING STATION. The pylon used on this station houses a 14- and
30-inch BER (MAU-12/B), and it will contain two cartridges for stores release
(see figure 10-21). When this bomb rack is installed no provisions are made
to jettison the pylons (see table (III). The bomb rack has provisions for
one electromechanical safety pin and the stores are released by inserting a
3/8-inch square drive tool into the release hole and rotating it (see figure
10-21). This pylon can also be used for carrying and launching various mis­
siles by using missile adapters (see table III). The following adatpers are
used:
1. LAU-34 (see figure 10-22). This adapter is used to suspend and
launch the AGM-12/B missile or the AGM-45 missile. The adapter consists of
the necessary electronics to launch and jettison the missiles. One explosive
cartridge is installed in the aft portion of the LAW-34 for missile jettison
(see figure 10-23). The adapter is loaded into the MAU-12B bomb rack by
using the 30-inch hooks of the rack (see figure 10-24). Ground safety pinning
is accomplished by using the electro-mechanical safety pin provided for the
pylon. With the LAU-34 installed, manual release of the missile can be accom­
plished by either rotating the missile release handle on the adapter (see figure
10-22) or by rotating the bomb rack release mechanism.
CAUTION
When the LAU-34 adapter is installed on the
pylon, the two bomb ejection cartridges for
the MAU-12/B bomb rack are normally not
installed. Be sure you check the cartridge
holders for the presence of cartridges.
2. LAU-7/A missile launcher (adapter) (see figure 10-24). This adapter
is bolted, one on each side of the pylon (see figure 10-25), and is used to
launch the AIM-9 missile. These adapters use no explosive cartridges, but
they do contain a high pressure air bottle charged up to 3000 psi (see figure
10-24). The bottle has a pressure indicator and bleeder valve, and it must be
considered a potential hazard. Each adapter has a provision for a combination
safety pin and release handle (see figure 10-25). When the handle is inserted
in the hole provided (see figure 10-24), it electrically safes the missile
launch circuits. Rotating the handle will unlock the detends and the missile
can be removed from the launch rail.
CAUTION
The MAU-12/B bomb rack cartridge holders
should not contain cartridges. For your
own safety, check them.
10-14
3.
AIM-A missile adapter (see figure 10-26). Three missile adapters
can be mounted on one pylon. Two adapters are bolted to the sides of
the pylon and the third is suspended from the hooks of the MAU-12/B bomb
rack. This adapter, as with the LAU-7/A missile adapter, contains no explo­
sives, and the cartridges for the MAU-12/B rack are normally not installed.
Again, for your own safety check to be sure. The safety pin used is the
one provided for the MAU-12/B rack. The missiles are removed from the
adapters by pulling out on the release latch near the back of each adapter
and by sliding the missile forward and off the rails (see figure 10-26).
Outboard Wing Station
The pylon on the outboard wing station also houses a MAU-12/B BER.
All EOD procedures for this station will be the same as those for the in­
board wing station.
Navy Configuration
The Navy suspension and release systems differ considerably from
those of the Air Froce. Since the F-4 designed for the Navy and their
pylons are used by the USAF, the pylons are often being encountered in
SEA, we will discuss them briefly.
FUSELAGE STATIONS.
The AERO 27/A centerline BER and the four AERO
7/A fuselage missile pylons are the same as discussed previously.
INBOARD WTNO STATION. An LAU-17/A wing missile pylon is used on
this station vaee cigure 10-27). The pylon is designed to carry and launch
one AIM-7 (Sparrow) missile. The pylon has a provision for an electrical
safing pin (see figure 10-27), and is jettisoned by means of one explosive
bolt located in the upper forward portion of the pylon (see figure 10-27).
The missile is removed from the launch rail by actuating the keeper mechanism
(see figure 10-27) and sliding the missile off the rail. The LAU-27 pylon
can be adapted to carry the following airmunitions.
1. AIM-9 missiles by bolting the LAU-7 adapters to each side of
the pylon in the same way as described for the AF MAU-12.B pylon (see figure
10-24).
2. Standard airmunitions by bolting the 30-inch big adapter (see figure
10-28) to the botton of the pylon. This adapter contains no explosives and
the hooks are opened by rotating a hex stud at each hook (see figure 10-28).
3. AGM-12/B or AGM-45 by attaching an LAU-34 missile adapter to the
hooks of the 30-inch bomb adapter described in paragraph 2 above (see figure
10-29).
Outboard Station
The outboard station on the F-4 aircraft carries the outboard wing pylon
(see figure 10-30) which is normally used for a fuel tank. The pylon has a
set of 30-inch hooks, two cartridges for pylon jettison, an electromechanical
safing pin, and a manual release that uses a 3/8-inch alien key (see figure
10-30.) This pylon can also be adapted to carry bombs and missiles using the
same adapters as used on the LAU-47 wing missile pylon.

A-IE AIRCRAFT
General
The A-1E is a single-engine (propeller-driven), twin-place aircraft
(see figure 10-31) which is used extensively in SEA by both the USAF and
RVNAF. It has 15 external stations for carrying airmunitions. These stations
are as follows:
1.
Centerline station
2.
Inboard wing stations (2)
3.
Wing stations (12)
CENTERLINE STATION. The A-1E centerline station contains an Aero 3//t
bomb ejection rack with a 14 and 30-inch suspension and which uses one
(see table IV) explosive cartridge for stores ejection (see figure 10-32).
Access to the cartridge breech is through a panel along side the rack, and
the removal of the cartridge is accomplished by disconnecting the electric
lead and removing the breech cap (see figure 10-32). Manual release is
accomplished by pulling on the release cable (see figure 10-32) using the
same access panel.
INBOARD WING STATIONS. These two stations carry the MK51 bomb racks
(see figure 10-33) which can be either a 14-inch, a 30-inch, or 14 and 30- inch
suspension. There are no
losive cartridges passociated with these racks
(see table IV). A mecnanical ground safing pin is used and a manual release
is accomplished by pulling on the release cable (see figure 10-33). Access to
this cable is through a panel in a bomb rack fairing (see figure 10-33).
NOTE
The centerline (Aero 3/A) and the two in­
board (MK51) bomb racks can carry the MAU63 multiple rack (MR) (see figure 10-34). The
MAU-63 multiple rack is very similar to the MER.
The major difference is that gas pressure from
the explosive cartridge is used to open the bomb
hooks instead of forcing out on an ejector foot.
So in theory the racks used on the MAU-63 are
not "ejector” racks. They have one explosive
cartridge per rack (6 total), and the safety pins
and release are the same as the individual racks for
the MER. All EOD procedures required on the MER
and MAU-63 are the same.
10-18
WING STATIONS. There are provisions for installing 12 each Aero
14 bomb racks (6 per wing). These racks have a provision for a 14-inch
suspension only, and they do not have explosive cartridges. Provision has
been made for installation of a mechanical safing pin (see figure 10-35)
and release is accomplished by inserting a small pointed instrument (crimpers
or phillips screwdriver) into the release hole (see figure 10-35).
NOTE
The AERO 14 bomb racks also have a provision
for carrying and launching fixed fin rockets
such as the 5-inch HVAR (see figure 10-35).
