NOSEWHEEL STEERING UPPER TORQUE ARM ASSEMBLY MUST BE DISCONNECTED
PRIOR TO TOWINGAIRCRAFT. ROTATION OF NOSE WHEEL BEYOND THEIR NORMAL
LIMITS OF TRAVEL (82°) CAN CAUSE SERIOUS DAMAGE TO STEERING UNIT WITH
STEERING UNIT TORQUE LINKS DISCONNECTED, NOSE WHEELS ARE FREE TO ROTATE
360°.
TO PREVENT POSSIBLE DAMAGE TO AIRCRAFT, SECURE PIP PIN HANDLE IN AN
UPRIGHT POSITION BY ROUTING LANYARD AND CLIP ASSEMBLY AROUND FORWARD
SIDE OF NOSE LANDING GEAR NUTCRACKER SWITCH.
A QUALIFIED PERSON MUST BE STATIONED IN COCKPIT DURING ALL TOWING
OPERATIONS TO WATCH FOR HAZARDOUS CONDITIONS AND TO STOP AIRCRAFT IN
EVENT AIRCRAFT BECOMES DISENGAGED FROM TOWING VEHICLE.
DO NOT SET BRAKES PERMANENTLY WHILE THEY ARE IN A HEATED CONDITION.
FAILURE TO PULL PITOT STATIC CIRCUIT BREAKERS WILL RESULT IN BURNING PITOT
STATIC COVERS.
AFTER MOORING AND BEFORE FLIGHT, CHECK THAT MOORING RINGS ARE FREE TO
PIVOT AND TORSION SPRINGS ARE HOLDING RINGS IN CONTACT WITH MAIN AND
NOSE STRUTS. AS A RECOMMENDED PRECAUTION, SPRINGS SHOULD BE SAFETY
WIRED TO STRUT AFTER USE.
THE GROUND ATTACHMENT POINT AT THE NOSE LANDING GEAR MUST BE CAPABLE
OF A MINIMUM LOAD OF 5,000 POUNDS EACH. THE GROUND ATTACHMENT POINT AT
THE MAIN LANDING GEAR MUST BE CAPABLE OF A MINIMUM LOAD OF 15,000 POUNDS
EACH.

Nose Gear Towing
1.
Ensure main landing gear and nose landing gear safety pins are installed.
2.
Remove steering safety (pip) pin from upper torque arm and steering collar unit as follows:
A. Disconnect safety lanyard from handle.
B. Remove safety pin from right hand side.
C. Depress pippin plunger and remove pippin from nose wheel steering upper torque arm and steering unit. Collar by hand.
D. Slowly lower nose wheel steering upper torque arm.
Note: the nose wheel steering upper torque arm is spring loaded to lie forward. This prevents torque arm from falling back while aircraft is being towed.
3. Insert and inspect pip pin in steering collar unit as follows:
A. Check that balls work freely when plunger is depressed.
B. Check that balls cannot be moved when plunger is released.
C. Discard pip pin that fail this inspection.
D. Inspect for position of locking balls by attempting to withdraw pip pin without depressing plunger.
NOTE: Inserting pip pin in lower power steering unit after torque arm has been disconnected will keep pip pin from being lost or damaged while aircraft is being towed.

4. Check nose strut inflation by determining di-14. Mention "x" as shown on nose landing strut inflation instruction plate:
A. If dimension "x" exceeds 13.6 inches, do not16. Tow aircraft
B. If aircraft has not been refueled, consider adding fuel to aircraft to enable heavier gross weight to lower aircraft.
C. If dimension "x" still exceeds 13.5 inches, deflate nose strut in accordance with procedures shown on nose landing strut inflation instruction plate.
D. If dimension "x" is less than 4.65 inches, inflate nose strut in accordance with procedures shown on nose landing strut inflation instruction plate or do not exceed 60° turning.
5. Towing procedures are basically same as those used for other aircraft equipped with tricycle landing gear.
6. Gulfstream aircraft can be towed forward or be pushed aft on hard surfaces using Gulfstream Aerospace approved tow bars attached to nose gear.
7. Connect tow bar to nose landing gear axle.
8. Connect tow bar to towing vehicle.
9. Disconnect ground wire from aircraft to ground.
10. A qualified person must be stationed in cockpit during all towing operations to watch for hazardous conditions and to stop aircraft in event tow bar becomes disengaged from towing vehicle. Note: It is desirable to establish communication between tow vehicle operator and person in the cockpit.
11. Check hydraulic brake accumulator gage for available pressure. Fully charge accumulator if pressure is below 3000 psi minimum required pressure.
12. Ensure gust lock is on.
13. Close main entrance door or support open door with jury cable.
14. Remove aircraft chocks.
15. Ensure landing gear is free of obstructions.
16. Release parking brake.
17. Tow aircraft making smooth starts and stops with towing vehicle. Tow in low gear only. Station wing and tail walkers as necessary to ensure clearance between aircraft and adjacent structure equipment
18. When destination is reached, apply aircraft parking brake.
19. Install chocks in front and behind lh and rh main landing gear tires.
20. Connect ground wire from aircraft to ground.
21. Disconnect tow bar from towing vehicle.
22. Install steering pip pin as follows:
A. If necessary, release parking brake.
B. Depress plunger on pippin handle and remove from steering collar unit.
C. Using tow bar, move nose wheels to align holes of nose wheel steering upper torque arm and steering collar unit.
D. Install pippin by depressing plunger and inserting pin into nose wheel steering upper torque arm and power steering unit from left to right.
E. Inspect for position of locking balls by attempting to withdraw pip pin without plunger
23. Secure pippin by connecting safety lanyard to handle.
24. Install safety pin in right hand side of pip pin.
25. Disconnect tow bar from nose landing gear axle.
26. Ensure main entrance door is clear to open, and open if required.
27. Secure aircraft as required.

Aircraft parking
Install ground safety locks (pip pins) in lower end of main landing gear side brace actuator and nose landing gear. Install ground safety locks (pip pins) through trunnion uplock hook of nose landing gear
Ensure gust lock lever is on. Check brake accumulator pressure gage on copilot inboard skirt panel for an indication of at least 1500 psig. If accumulator pressure is below 1500 psig pressure, charge accumulator.
Set parking brakes by pulling park/emergency brake handle in cockpit. Chock main landing gear wheels forward and aft. Release parking brakes after wheel chocks are in place by releasing park/emergency brake handle in cockpit Protect tires with covers. Install following protective covers:
Engine inlet covers, two required engine exhaust covers, two required nacelle cooling air covers, two required low pressure cooling air outlet covers, two required Thrust reverser scoop assembly covers, two required Pitot covers, two required Close, latch, and lock main entrance door and baggage door.
Remove battery connectors from battery if aircraft is to be parked for three days or more Moor aircraft if weather conditions warrant
Secure Aircraft

Install ground safety locks (pip pins) in lower end of main landing gear side brace actuator and nose landing gear.

Install ground safety locks (pip pins) through trunnion up-lock hook of nose landing gear.

Choose an area away from runways, taxiways and other areas where dust, debris, prop-wash and jet exhaust could pose a problem.
 Position aircraft so that a minimum clearance from other aircraft or structures is equivalent to aircraft maximum length plus 16 feet

Park aircraft on level ground, with nose into wind.

Attach tie down lines to mooring rings on both main and nose gear. Note: The prevailing weather conditions will determine number of tie down lines.

Ensure gust lock lever is on.
 Check brake accumulator pressure gage for an indication of at least 3000 psig. If accumulator pressure is below 3000 psig pressure, charge accumulator.

Set parking brakes by pulling park/emergency brake handle in cockpit.

Chock main landing gear wheels forward and aft.

Release parking brakes after wheel chocks are in place by releasing park/emergency brake handle in cockpit
 Install all protective covers.


Close, latch, and lock main entrance door and baggage door.
Remove battery connectors from battery if aircraft is to be parked for three days or more
