(2) Do the operational test of the automatic change-over function (Ref. AMM TASK 22-60-00-710-002).
4. Fault Isolation
_______________
A. If the operational test of the AFS gives the maintenance message AFS: FAC 2/RTL ENGD FDBK:
(1) If the operational test of the automatic change-over function gives the maintenance message AFS: FAC 1/RTL ENGD CHG-OV:
- replace the FAC-2 (1CC2), (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(a) If the fault continues:
- do a check and repair the wiring of the RTL ENGD COM and RTL ENGD MON discretes from the FAC 2 (1CC2) to the first terminal block (Ref. ASM 22-68/02).

(2) If there is no message after the operational test of the automatic change-over function:
- replace the FAC 2 (1CC2) (Ref. AMM TASK 22-66-34-000-002) and (Ref. AMM TASK 22-66-34-400-002).
(a) If the fault continues:
- do a check and repair the wiring of the RTL OWN ENGD COM and RTL OWN ENGD MON discretes from the FAC 2 (1CC2) to the first terminal block (Ref. ASM 22-68/02).
B. Do the operational test given in Para. 3.A.(1).
Loss of the Rudder Travel Limiting Function on the FAC 1
1. Possible Causes
_______________
- LIMITATION UNIT-RUDDER TRAVEL (4CC)
- RELAY-RTL SYS1 (13CC1)
- FAC-1 (1CC1) R - SENSOR-TAT, 1 (11FP1)
- wiring for 28VDC signal (pin A2) and GND signal (pin X2) at the relay (13CC1)
- wiring of the RTL ACT VALID signal from the FAC1 to the RTLU and associated GND signal at the RTLU
- electronic module
- wiring of the RTL ACT PWR ON signal from the FAC1 to the relay 13CC1
- wiring of the 28VDC and GND at the RTLU (PWR SPLY)
- wiring from the FAC 1 (1CC1) to the rudder travel-limitation unit (4CC)
- wiring of the RTL V1 and RTL V2 discretes from the FAC 1 (1CC1) to the rudder travel-limitation unit (4CC)

3. Fault Confirmation
__________________
A. Make sure that this(these) circuit breaker(s) is(are) closed:
-------------------------------------------------------------------------------PANEL DESIGNATION IDENT. LOCATION -------------------------------------------------------------------------------49VU AUTO FLT/FAC1/28VDC 5CC1 B04
B. 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/RTL ACTR 4CC:
- remove the relay 13CC1 (open the circuit breaker 5CC1 before and close it after)
- do a check of the correct wiring for 28VDC signal (pin A2) and GND signal (pin X2) at the relay (13CC1), if no repair it (Ref. ASM 22-68/02)
- open the circuit breaker 5CC1
- remove the FAC-1 (1CC1) (Ref. AMM TASK 22-66-34-000-002)
- install the above removed relay (13CC1).
(1) Do a check of the impedance of the RTL ACT VALID signal between the pin AB/11A and the pin AC/3 (GND signal) of the FAC-1 rack connector, (Ref. ASM 22-68/02) and (Ref. ASM 22-67/01).
