(O) May be inoperative provided:
a) Both valves are verified closed,
b) PAC Switches remain OFF,
c) Wemac Boost is operational,
d) Aircraft is operated unpressurized,
e) Aircraft is operated at or below 10,000 MSL, and
f) Baggage compartment remains empty.

Start both engines.
Ensure APU is shut down and Wemac Boost is OFF.
Position CKPT PAC and CABIN PAC selectors to OFF.
Place ISOL VALVE to the CLSD (vertical) position.
Close all cabin overhead outlets (Wemacs) and open cockpit
overhead air outlets.
a. There should be no airflow from the cockpit overhead air
outlets.
Switch to manual pressurization and select and
hold the
manual control toggle (cherry picker) to the DOWN position. No
change in cabin rate should be observed on the cabin rate-ofclimb indicator.
Shut down engines.
Place placard adjacent to the environmental control
panel stating, "COCKPIT AND CABIN PAC's INOP."
Make appropriate discrepancy report entry.
NARRATIVE
With both bi-level flow control valves inoperative, the aircraft may be
dispatched if both valves are verified in the closed position. No
airflow out of either PAC will indicate that both bilevel flow control
valves are in the closed position. Using the manual pressurization is
a secondary check to ensure the valves are closed and the cabin is
not being pressurized. However, presence of airflow indicates one or
both valves are stuck in the open position and further troubleshooting
should be initiated prior to aircraft dispatch.

For all scenarios: Prior to door closing, crew will advise all passengers as
to the operational status of the toilet.
To deactivate a toilet that will not flush:
1. Make appropriate discrepancy report entry.
2. Disengage and tie-wrap the “TOILET POWER” circuit breaker
located behind the upper fwd lavatory drawer (to the right of the
sink when viewed from the toilet).
3. To check for leaks:
(a) On toilets without inspection ports installed in cover:
i) Remove seat back and seat pad.
ii) Raise toilet seat and remove screws.
iii) Remove toilet cabinet top by removing screws and
disconnecting flush switch connector.
iv) Check all hoses, connections, and general area for leaks.
(b) On toilets with inspection ports installed in cover (Ref: SB75025-11):
i) Remove seat back and seat pad.
ii) Using a port to observe, and another to shine a flashlight,
observe thru each available inspection port to check hoses,
connections and general area for leaks.
4. Any leaked fluid must be removed from the aircraft. If the tank will
not hold fluid, go to step 6.
5. If desired, flush toilet manually as follows:
(a) Observe fluid level under the rubber flapper at the bottom of
the bowl. If the tank is full, drain it using an appropriate ground
service vehicle, following the instructions on the placard located
inside the exterior service panel door. Then, with an empty tank,
(b) Pour 2 gallons of proper toilet solution into the bowl, rinsing the
bowl as the fluid is poured.
6. If desired, service the toilet using an appropriate ground service
vehicle, following the instructions on the placard located inside the
exterior service panel door.
7. Following servicing or flushing, re-inspect the toilet system for
leaks. If the tank drains into the drain line, leave the tank empty
and:
(a) To prevent damage from freezing, empty the drain line into a
ground service cart, and
(b) To account for the missing toilet solution, either
i) Adjust Zero Fuel Weight and ZFW-Moment for each flight by
subtracting 15 pounds and 61.50 Inch-pounds/100 from the
calculated Zero Fuel Weight and moment, or
ii) Add 15 pounds of ballast at the toilet fuselage station (FS
410). Soft ballast, such as a shot bag, can be placed in the toilet
bowl (in a sturdy sealed plastic bag, if possible). Other ballast
options include the vanity drawers/cabinets, with 15 to 16 pounds
distributed evenly fore and aft of the sink.

Verify normal start pressure (greater than 30 PSI) is available.
Use a 1/4" socket to turn the hex fitting at the bottom
of the affected engine start valve to the OPEN index mark.
Start the engine on the affected engine start valve
side.
After engine starts, turn the hex fitting at the bottom of
the affected engine start valve to the CLOSED index mark.
Verify no START VLV OPEN L or START VLV OPEN
R EICAS indication exists.
Place placard adjacent to the EICAS display stating, "LEFT/RIGHT
ENG START VALVE INOP."
Make appropriate discrepancy report entry.
NARRATIVE:
Bleed air pressure will attempt to pressurize the start valve closed
during start. The start valve must be held in the open position until
normal sequence is terminated. The engine will start to rotate as soon
as the start valve is turned to the open position. EICAS displays an
indication of the engine start valve position. If the start valve remains
open after engine start, the EICAS message START VLV OPEN L or
START VLV OPEN R will display amber in color. In addition, the
associated engine start button light will remain illuminated if the start
valve stays open.

78 THRUST REVERSER DISABLING - MAINTENANCE PRACTICES
1.
General
A.
The thrust reverser system shall be disabled with the doors stowed and locked. Disabling is
accomplished by physically locking thrust reverser door latches and disconnecting electrical and
hydraulic power. One or both thrust reversers may be disabled for flight.
(1)
B.
2.
Enabling is the procedure to render thrust reversers operational after disabling.
Description
A.
The thrust reverser system is disabled mechanically and electrically.
(1)
(2)
B.
3.
Disabling is the procedure to render one or both thrust reversers inoperable and still permit
normal flight operation.
Mechanical disabling consists of inserting latch pins in the outboard latch boxes to physically
prevent the thrust reverser door latches from moving.
Electrical disabling consists of disengaging and locking out appropriate circuit breakers.
Placards are placed in cockpit to alert crew to disabled thrust reversers.
Dispatch With Inoperative Thrust Reverser(s)
NOTE:
A.
If only one thrust reverser is to be disabled, accomplish only those steps which are applicable
to that thrust reverser. One or both thrust reversers may be disabled for flight.
To disable the thrust reversers, use the following procedure:
(1)
(2)
(3)
(4)
Ensure the thrust reversers are in the stowed and latched position.
In the cockpit, disengage LH T/R STOW, LH T/R DEPLOY, RH T/R STOW and RH T/R
DEPLOY circuit breakers, located on the left circuit breaker panel. Install MS35489-6
Grommets in all four circuit breaker locations.
Remove inboard fairing inspection panel and physically inspect that the lower door hook is
engaged in the door latch receptacle. Inspect that the upper door hook is engaged through
fairing/door gap at hook locations.
Physically inspect that both the upper and lower hooks are engaged in the door latch
receptacles on the outboard side through fairing/door gap at hook locations.
WARNING: IF THERE IS EVIDENCE OF DAMAGE IN THIS AREA, OR
THE DOOR HOOKS ARE NOT ENGAGED IN THE DOOR
LATCH RECEPTACLES, REPAIRS SHALL BE MADE PRIOR
TO RELEASING THE AIRPLANE FOR FLIGHT.
(5)
(6)
Remove outboard thrust reverser fairing panel to pin thrust reverser assembly, and store.
From the Thrust Reverser Pinning Kit, remove latch quick release pin (MS17984C313) and
insert through latch box in two places on the outboard side to block both the upper and lower
hooks from movement.
(7) From the Thrust Reverser Pinning Kit, remove thrust reverser fairing panel (red in color) and
install on outboard thrust reverser fairing.
(8) Reinstall the inspection panel on inboard thrust reverser fairing.
(9) Placard thrust reverser control panel, or thrust reverser enunciator(s) with "T/R
INOPERATIVE" warning, as shown in Appendix A-7.
(10) Make logbook entry to alert flight crew of inoperative thrust reverser condition.
