Not applicable, the fault is evident.
4. Fault Isolation
_______________
A. If vibration and noise occur during braking:
- do an inspection/check of the wheels (Ref. AMM TASK 32-41-00-210-002).
(1) If the inspection/check of the wheels is OK:
- do an inspection/check of the brake (Ref. AMM TASK 32-42-27-210-001).
(a) If the inspection/check of the brake is not OK:
- replace the defective BRAKE-WHEEL 2 (2641GM) or BRAKE-WHEEL 4 (2642GM) or BRAKE-WHEEL 1 (2643GM) or BRAKE-WHEEL 3 (2644GM). (Ref. AMM TASK 32-42-27-000-001) and (Ref. AMM TASK 32-42-27-400-001)
(b) If the inspection/check of the brake is OK:
- remove the wheel to do a check of the wheel balance.
(2) If the inspection/check of the wheels is not OK:
- replace the defective WHEEL-MLG, 2 (2649GM) or WHEEL-MLG, 4 (2650GM) or WHEEL-MLG, 1 (2651GM) or WHEEL-MLG, 3 (2652GM). (Ref. AMM TASK 32-41-11-000-006) and (Ref. AMM TASK 32-41-11-400-006)
B. After the subsequent flight, make sure that the fault does not continue.
