A. Procedure
(1) Do a check of the post flight report. If there is LGCIU 1 and 2 FAULT ECAM messages and related NLG door-closed target-position CFDS messages, 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 NLG doors.
(1) Do the detailed visual inspection of the nose landing gear doors operating mechanism (Ref. AMM TASK 32-30-00-200-001).
(2) Do a check of the nose gear door gaps and mismatches (Ref. AMM TASK 32-22-00-220-001).
(3) Do the detailed visual inspection of the NLG door uplock units and pins (Ref. AMM TASK 32-31-00-200-001).
(4) Do the detailed visual inspection of the NLG door hinges (Ref. AMM TASK 52-82-00-200-001).
(5) Correct any fault found.
(6) Do the functional test of the normal extension and retraction of the nose landing gear (Ref. AMM TASK 32-31-00-720-003).
(7) If the fault continues replace the UPLOCK ASSY-NLG DOOR (2534GM) (Ref. AMM TASK 32-31-14-000-001) and (Ref. AMM TASK 32-31-14-400-001).
(8) If the fault continues, the NLG doors are slow to operate or the fault continues after the subsequent flight, replace the ACTG CYL-NLG DOOR (2531GM) (Ref. AMM TASK 32-31-16-000-001) (Ref. AMM TASK 32-31-16-400-001). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 起落架 LANDING GEAR 1(51)
