 (3) On the nose gear leg,on the N/W steering deactivation electrical box:
 - make sure that the towing lever is in the TOWING position (disengaged position)
 NOTE : : Two square steel plates are necessary.
____
 (4) Put one of the steel plates in position in front of the nose wheels.

 (5) Apply a thick layer of COMMON GREASE (Material No. 04-004) to the top of the greased steel plate.

 (6) Put the other steel plate on the top of the greased steel plate.

 (7) Move the aircraft and put the nose wheels on the steel plates (Ref. AMM TASK 09-10-00-584-002).

 NOTE : : Do not disconnect the tow bar from the aircraft.
____
 (8) With the tow bar, try to steer the nose wheels.
 4. Fault Isolation
_______________
 A. If the steering is not possible during the test:
 - replace the SERVO CTL-N/W STEERING (6GC) (Ref. AMM TASK 32-51-51-000-001) (Ref. AMM TASK 32-51-51-400-001)
 (1) If the fault continues:
 - replace the BSCU (10GG) (Ref. AMM TASK 32-42-34-000-001) (Ref. AMM TASK 32-42-34-400-001)
 B. Do the test given in Para. 3. A.
 5. Close-up
________
 A. Put the aircraft back to its initial configuration.
 (1) Depressurize the Green hydraulic system (Ref. AMM TASK 29-10-00-864-001).

 (2) De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).

 (3) Move the aircraft and remove the greased plates (Ref. AMM TASK 09-10-00-584-002)

 (4) Make sure that the work area is clean and clear of tool(s) and other items.
