_______________
A. If the test gives the maintenance messages:
AFS: FMGC2/AP ENGD FDBK
AFS: FMGC1/AP2 ENGD WIRG
AFS: FAC1/AP2 ENGD WIRING
- remove the FMGC-1 (1CA1) (Ref. AMM TASK 22-83-34-000-001)
- do the operational test of the AFS (Ref. AMM TASK 22-96-00-710-001).
(1) If the test gives the message: AFS TEST OK
- replace the FMGC-1 (1CA1) (Ref. AMM TASK 22-83-34-400-001).
(2) If the test result of the FMGC2 gives the maintenance message AFS: FMGC2/AP ENGD FDBK:
- replace the FMGC-2 (1CA2) (Ref. AMM TASK 22-83-34-000-001) and (Ref. AMM TASK 22-83-34-400-001).
