A. Aircraft Maintenance Configuration
(2) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(3) Make sure that the hydraulic systems are depressurized
(Ref. AMM TASK 29-10-00-864-003), (Ref. AMM TASK 29-23-00-864-001) and (Ref. AMM TASK 29-24-00-864-001).
(4) On the overhead panel 23VU (24VU), make sure that:
Subtask 27-93-00-865-058-A NOTE: This Aircraft Maintenance Configuration is for the ELAC1. For the ELAC2, use the indications between the parentheses.
(1) Make sure that the aircraft is in the ground condition. (2) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(3) Make sure that the hydraulic systems are depressurized

A. Do a check of the reference of the software loaded in the ELAC
(2) Make sure that the P/N of the ELAC shown on the LRU IDENTIFICATION page is the one of a permitted configuration (refer to Airline Configuration Management Document).
(a) If the P/N of the ELAC shown on the LRU IDENTIFICATION page is different from the PN(s) given in the Airline Configuration Management Document, replace the ELAC (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
5. Close-upNOTE: This procedure is for the ELAC1. For the ELAC2, use the indications between the parentheses.
(1) Do the procedure to get access to the SYSTEM REPORT/TEST F/CTL page (Ref. AMM TASK 31-32-00-860-006). | ACTION | RESULT |
|---|---|
| 1.Push the line key adjacent to the EFCS 1(2) indication. |
