Failure of the Rudder Trim/Reset Circuit of the FAC 1
1. Possible Causes
_______________
- FAC-1 (1CC1)
- P/BSW-RUD TRIM/RESET (8CC)
- wiring of the RUD TR RES NO MON discrete (from the FAC 1 (1CC1) to the RUD TRIM/RESET pushbutton switch (8CC))
- wiring of the ground signal at RUD TRIM/RESET pushbutton switch (8CC)
- wiring of the RUD TR RES NC COM discrete (from the FAC 1 (1CC1) to the RUD TRIM/RESET pushbutton switch (8CC))

__________________
A. Test
(1) Do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FAC 1:
(a) With the RUD TRIM/RESET pushbutton switch (8CC) pushed.
(b) With the RUD TRIM/RESET pushbutton switch (8CC) released.
4. Fault Isolation
_______________
A. If only the first test gives the maintenance message AFS : FAC1/RT RESET SW 8CC:
- replace the FAC-1 (1CC1), (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(1) If the fault continues:
- replace the P/BSW-RUD TRIM/RESET (8CC).
