4. Fault Isolation
_______________
A. Procedure NOTE : The procedure that follows, gives the information necessary to
____ identify mechanical faults related to the NLG shock absorber.
(1) Do the general visual inspection of the nose landing gear (Ref. AMM TASK 32-21-00-200-002).
(2) Do the inspection of the NLG proximity sensor and target clearances (Ref. AMM TASK 32-31-73-200-002).
(3) Do the inspection/check of the NLG torque link assembly (Ref. AMM TASK 32-21-00-200-003).
(4) Do the check of the charge pressure of the nose landing gear (NLG) shock absorber (Ref. AMM TASK 12-14-32-614-004).
(5) Do the replenishment of the NLG shock absorber (Ref. AMM TASK 12-12-32-611-005).
(6) Correct any fault found.
(7) Do the functional test of the normal extension and retraction of the nose landing gear (Ref. AMM TASK 32-31-00-720-003).
