3. Fault Confirmation
__________________
A. Do a read out of the post flight report.
NOTE : The fault cannot be reproduced on the ground. You must fly the
____ aircraft to see if the corrective action has been succesfull or not.
4. Fault Isolation
_______________
A. Restricted Pack Controller Fault Isolation
NOTE : This procedure is only applicable for:
____
- Pack Controller Part Number 759A0000-xx
- Pack Controller Part Number 759C0000-xx
(1) If the post flight report gives the warning PACK 2 without a maintenance message:
- swap the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(a) If the fault moves with the PC 2:
- swap back the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
- replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(2) If the fault does not move with the PC 2:
- swap back the PC 2 (27HH) and the PC 1 (7HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
- disconnect the electrical connector (31HHA) (Ref. AMM TASK 21-61-13-000-001).
- make sure that the electrical connector is clean and in the correct condition.
- do a check for voltage at the electrical connector (31HHA) between pins C and D (Ref. ASM 21-61/02).
