__________________
A. Test
(1) If a shock-absorber proximity-sensor (20GA thru 25GA) target position message is shown on the Post Flight Report (PFR), do the applicable functional test of the Main L/G (Ref. AMM TASK 32-31-00-720-002), or Nose L/G (Ref. AMM TASK 32-31-00-720-003):
- if the initial test is OK, continue and do the inductance check in Para. 4.A., for all the shock-absorber proximity-sensors
- if during the initial test, the L/G control lever does not move to the UP position, do the fault isolation procedures in Para. 4.A., then do the trouble shooting for the L/G control-lever baulk-solenoid (Ref. TASK 32-31-00-810-885)
- if a subsequent test is OK, after the fault isolation procedure(s) has been done, no more maintenance work is necessary.
NOTE : If the L/G lever does not move to the UP position there will
____ be two faults, one in System 1 and one in System 2. If the shock-absorber proximity-sensors are serviceable and the L/G lever does not move, then the two faults are in the L/G lever unit, or the LGCIU, or the related aircraft wiring. If one of the two faults goes, the L/G lever will operate correctly, but the fault in the opposite system stays. Thus it is also necessary to do the L/G lever trouble shooting task to find the other fault.
4. Fault Isolation
_______________
A. Procedure
(1) For the applicable proximity sensor shown on the Post Flight Report (PFR), do the inspection of the gap between the proximity-sensor and its target, (Ref. AMM TASK 32-31-73-200-001) or (Ref. AMM TASK 32-31-73-200-002).
