(a) Replace the applicable uplock assembly:

 - for the MLG uplock proximity sensor faults (8GA; 9GA; 10GA; 11GA) replace the applicable uplock assembly 2509GM (2510GM), (Ref. AMM TASK 32-31-44-000-001) and (Ref. AMM TASK 32-31-44-400-001).

 - for the NLG uplock proximity sensor faults (12GA; 13GA) replace the uplock assembly 2530GM, (Ref. AMM TASK 32-31-21-000-001) and (Ref. AMM TASK 32-31-21-400-001).

 - for the MLG door uplock proximity sensor faults (26GA; 27GA; 28GA; 29GA) replace the MLG door uplock assembly 2521GM (2520GM), (Ref. AMM TASK 32-31-33-000-001) and (Ref. AMM TASK 32-31-33-400-002).

 - for the NLG door uplock proximity sensor faults (30GA; 31GA) replace the door uplock assembly 2534GM, (Ref. AMM TASK 32-31-14-000-001) and (Ref. AMM TASK 32-31-14-400-001).

 (b) if the fault continues, do step (7).

 (6) If the proximity sensor is serviceable, do the applicable functional or operational test that follows, to confirm that the fault occurs:

 - for the MLG (Ref. AMM TASK 32-31-00-720-002)

 - for the NLG only (Ref. AMM TASK 32-31-00-720-003)

 - for the L/G doors (Ref. AMM TASK 32-31-00-710-002) or (Ref. AMM TASK 32-31-00-710-002).

 - if the fault continues, do the next step.

 (7) Replace the applicable LGCIU-1 (5GA1) or LGCIU-2 (5GA2) which identified the fault, (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

 3. Fault Confirmation
__________________
 A. Test
 (1) If the conditions that follow are shown, do the fault isolation.
 (a) During retraction and extension of the landing gear there is vibration and noise.

 (b) During servicing, the MLG FWD pintle bearing is difficult to lubricate.

 4. Fault Isolation
_______________
 A. Procedure
 (1) Lubricate the FWD pintle bearing (Ref. AMM TASK 12-22-32-640-001), use both grease nipples (when accessible). Lubricate for another 20 strokes after fresh grease comes out of the pintle bearing.
