 4. Fault Isolation
_______________

 A. Procedure
 NOTE : The procedure that follows, gives the information necessary to
____
 identify mechanical faults related to the MLG (RH) door.

 (1) Do a detailed inspection of the MLG (RH) doors operating mechanism. Inspect the components for:

 - security of attachment

 - damage

 - corrosion
 - oil leaks.

 (2) Do the detailed visual inspection of the MLG (RH) door uplock units and pins (Ref. AMM TASK 32-31-00-200-001).

 (3) Do the detailed visual inspection of the MLG (RH) door 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, R (2520GM) (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 (RH) is slow to operate or the fault continues after the subsequent flight, replace the ACTG CYL-MLG DOOR, R (2522GM) (Ref. AMM TASK 32-31-35-000-001) and (Ref. AMM TASK 32-31-35-400-001).
