4. Fault Isolation
_______________
A. Procedure NOTE : The procedure that follows, gives the information necessary to
____ identify mechanical faults related to the MLG (RH).
(1) Do the inspection/check of the main gear (RH) (Ref. AMM TASK 32-11-00-200-001).
R (2) Do a check of the UPLOCK ASSY-MLG, R (2510GM) proximity sensors and R targets (Ref. TASK 32-31-00-810-846).
R (a) If the indications are not correct during the check, do the R following:
R 1_ Do a check for grease contamination of the uplock proximityR sensors and targets.
R 2_ If there is too much grease in the area, clean off the greaseR and do the check in Para. 4.A. again.
R NOTE : Grease contamination can cause incorrect indications.
____ R
(3) Do the detailed dimensional check of the MLG (RH) lockstay assembly (Ref. AMM TASK 32-11-00-220-003).
(4) Do the detailed inspection of the MLG (RH) uplocks (Ref. AMM TASK 32-31-00-200-001).
R (5) Correct all faults found.
(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 (RH) is slow to operate or the fault continues after the subsequent flight, replace the ACTG CYL-MLG R (2504GM) (Ref. AMM TASK 32-31-46-000-001) (Ref. AMM TASK 32-31-46-400-001).
