A. Job Set-Up
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(b) Pressurize the aircraft hydraulic systems (Ref. AMM TASK 29-23-00-863-001) (Ref. AMM TASK 29-24-00-863-001) (Ref. AMM TASK 29-10-00-863-003).
B. Make sure that this(these) circuit breaker(s) is(are) closed:
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------
49VU AUTO FLT/FAC1/28VDC 5CC1 B04
C. Test
(1) Open the circuit breaker 5CC1.
(2) After a minimum of 10 seconds, close the circuit breaker 5CC1.
(3) After 2 minutes, do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001) and read the result for the FAC 1.
4. Fault Isolation
_______________
A. If the test gives the maintenance message AFS : FAC1/YD RVDT BOX 2CC:
- 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:
- do a check of the wiring of the 26VAC signal at RVDT box (2CC) from pin A/A to the first terminal block (Ref. ASM 22-68/04).
(a) If there is no continuity:
- repair the above wiring.
(b) If there is continuity:
- do a check of the wiring of the ground signal at RVDT box (2CC) pin A/B (Ref. ASM 22-68/04).
1 If there is no continuity:
_
- repair the above wiring.
2 If there is continuity:
_
- replace the XDCR UNIT-YAW DAMPER POS (2CC), (Ref. AMM TASK 27-26-17-000-001) and (Ref. AMM TASK 27-26-17-400-001).

(2) If the fault continues:
- do a check and repair the wirings of the YAW V1 MON and YAW V2 MON discretes (from the RVDT box (2CC) to the FAC 1 (1CC1) (Ref. ASM 22-68/04).
B. Do the operational test of the yaw damper function (Ref. AMM TASK 22-63-00-710-001).

CES Loss of the Signal from the Yaw-Damper Position Transducer-Unit (2CC) to the FAC 2
1. Possible Causes
_______________
- FAC-2 (1CC2)
- XDCR UNIT-YAW DAMPER POS (2CC)
- wiring of the 26VAC signal at RVDT box (2CC)
- wiring of the ground signal at RVDT box (2CC)
- wirings of the YAW V1 MON and YAW V2 MON discretes (from the RVDT box (2CC) to the FAC 2 (1CC2)
