4. Fault Isolation
_______________
A. Procedure
NOTE : The procedure that follows, gives the information necessary to
____ identify mechanical faults related to the MLG (LH) door.
(1) Do a detailed inspection of the MLG (LH) doors operating mechanism . Inspect the components for:
- security of attachment
- damage
- corrosion
- oil leaks.
(2) Do the detailed visual inspection of the MLG (LH) door uplock units and pins (Ref. AMM TASK 32-31-00-200-001).
(3) Do the detailed visual inspection of the MLG (LH) forward and aft fitting (Ref. AMM TASK 52-81-00-200-001).
(4) Correct any fault found.
(5) If the fault continues, replace the UPLOCK ASSY-MLG DOOR, L (2521GM) (Ref. AMM TASK 32-31-33-000-001) (Ref. AMM TASK 32-31-33-400-002).
(6) Do the functional test of the normal extension and retraction of the landing gear (Ref. AMM TASK 32-31-00-720-002).
(7) If the fault continues, the MLG door (LH) is slow to operate or the fault continues after the subsequent flight, replace the ACTG CYL-MLG DOOR, L (2523GM) (Ref. AMM TASK 32-31-35-000-001) (Ref. AMM TASK 32-31-35-400-001).
