(2) Do the operational test of the L/G safety valve (Ref. AMM TASK 32-31-00-710-008):
- if the operational test is OK, do the fault isolation procedure in Para. 4.A.(6)
- if the operational test is not OK, do the fault isolation procedure in Para. 4.A.(1).
4. Fault Isolation
_______________
A. Procedure
(1) At the SAFETY VALVE-L/G SYS ISOLATION (49GA), release the electrical connector 49GA-A. (Ref. Fig. 201/TASK 32-31-00-991-010)
(2) Do a check for 28VDC at the free end of connector 49GA-A (Ref. ASM 32-31/07):
- if 28VDC is available, do step (5)
- if 28VDC is not available, connect the connector 49GA-A and do the next step.
(3) Replace the RELAY-HYDRAULIC CONTROL (48GA).
(a) Do the part of the operational test in Para. 3.A.(2) that does a check of the operation of the MLG doors (Ref. AMM TASK 32-31-00-710-008):
NOTE : To make sure that the hydraulic control relay is operating
____ correctly it is not necessary to do the check at 260 KTS.
- if the fault continues, do the next step.
(4) Do a check and repair as necessary the aircraft wiring (Ref. ASM 32-31/07):
- if the fault continues, do the next step.
(a) Do the part of the operational test in Para. 3.A.(2) that does a check of the operation of the MLG doors (Ref. AMM TASK 32-31-00-710-008):
- if the fault continues, do the next step.
(5) Replace the SAFETY VALVE-L/G SYS ISOLATION (49GA) (Ref. AMM TASK 32-31-17-000-001) (Ref. AMM TASK 32-31-17-400-001):
- if the fault continues, do the next step.
(6) Replace the SEL VALVE-L/G (40GA) (Ref. AMM TASK 32-31-12-000-001) and (Ref. AMM TASK 32-31-12-400-001).
