(5) Do the detailed visual inspection of the MLG (LH) uplock units and pins (Ref. AMM TASK 32-31-00-200-001).
(6) Correct any fault found.
(7) Do the functional test of the normal extension and retraction of the landing gear (Ref. AMM TASK 32-31-00-720-002).
(8) If the fault continues, the MLG (LH) is slow to operate or the fault continues after the subsequent flight, replace the ACTG CYL-MLG L (2503GM) (Ref. AMM TASK 32-31-46-000-001) and (Ref. AMM TASK 32-31-46-400-001).

(2) Do a check of the post flight report. If there is a L/G SYS DISAGREE ECAM message and related MLG (RH) downlock target-position CFDS message, do the Fault Isolation procedure.
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).
(2) Do the inspection of the MLG (RH) proximity sensors and target clearances (Ref. AMM TASK 32-31-73-200-001).
(3) Do the detailed dimensional check of the MLG (RH) lockstay assembly (Ref. AMM TASK 32-11-00-220-003).
(4) Do the visual inspection of the MLG (RH) downlock springs (Ref. AMM TASK 32-11-19-200-001).
(5) Do the detailed visual inspection of the MLG (RH) uplock units and pins (Ref. AMM TASK 32-31-00-200-001).
(6) Correct any fault found.
(7) Do the functional test of the normal extension and retraction of the landing gear (Ref. AMM TASK 32-31-00-720-002).
(8) 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) and (Ref. AMM TASK 32-31-46-400-001).
