.. the pin A/A2 of the RTL SYS 1 relay (13CC1)
.. the pin A/A2 of the RUD TRIM 1 relay (7CC1)
. the pin A/A1 of the RTL SYS 1 relay (13CC1) and the pin A/A of the
RUDDER TRAVEL limitation unit (4CC)
. the pin A/A1 of the RUD TRIM 1 relay (7CC1) and the pin B/T of the
RUDDER TRIM actuator (10CC)
(Ref. ASM 22-67/01).
(1) If the wiring is not correct:
- repair it.
(2) If the wiring is correct:
- replace the RTL SYS 1 - RELAY (13CC1) and the RUD TRIM 1 - RELAY (7CC1)
(3) If the fault continues:
- replace the ACTUATOR-RUDDER TRIM (10CC) (Ref. AMM TASK 27-22-51-000-001) and (Ref. AMM TASK 27-22-51-400-001).
(4) If the fault continues:
- replace the LIMITATION UNIT-RUDDER TRAVEL (4CC) (Ref. AMM TASK 27-23-51-000-001) and (Ref. AMM TASK 27-23-51-400-001).
(5) If the fault continues:
- replace the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(6) If the fault continues:
- do a check of the integrity of the SERVO ACTR-YAW DAMPER, 1 (3CC1) and FAC-1 (1CC1) by the following trouble shooting procedure (Ref. TASK 22-63-00-810-801).
NOTE : Disregard the maintenance message.
____
C. Do the Operational Test of the AFS (Ref. AMM TASK 22-96-00-710-001).
