A. Test
(1) Not applicable, you cannot confirm this fault on the ground.
4. Fault Isolation
_______________
A. If the post flight report gives the maintenance message:
ELAC1
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
NOTE : During the subsequent flights make sure that the fault does not
____ occur again. If this message is shown again replace, the SSTU-ROLL CTL, CAPT (4CE1) and the SSTU-ROLL CTL, F/O (4CE2), (Ref. AMM TASK 27-92-41-000-002) and (Ref. AMM TASK 27-92-41-400-002).
