A. Test
Not applicable, you cannot confirm this fault on the ground.
**ON A/C 301-399,
A. Test
(1) Do the operational test of the side stick assembly (activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
(2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).

A. If the POST FLIGHT REPORT (PFR) gives the maintenance messages: L B AIL MODE XDCR 33CE3 OR INPUT OF ELAC1 and R G AIL MODE XDCR 33CE4 OR INPUT OF ELAC1
- remove the ELAC1 (Ref. AMM TASK 27-93-34-000-001).
(1) At the ELAC1 receptacle, do a check of the resistance and of the insulation between the pin AD/2C and the pin AD/2D (15 to 250 ohms) (Ref. ASM 27-93/02).
(a) If the resistance values are in the specified limits:
- replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(b) If the resistance is less than 15 ohms:
1 Do the trouble shooting procedure (Ref. TASK 27-90-00-810-
_
801).
2 Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and
_ (Ref. AMM TASK 27-93-34-400-001).
(c) If the resistance is more than 250 ohms:
1 Do a check and repair the wiring of the ACS2 signal from the
_ ELAC1 MON side to the first terminal block (Ref. ASM 27-93/02).
2 Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).

A. If the test gives the maintenance messages:
L B AIL MODE XDCR 33CE3 OR INPUT OF ELAC1
and
R G AIL MODE XDCR 33CE4 OR INPUT OF ELAC1
- remove the ELAC1 (Ref. AMM TASK 27-93-34-000-001).
R (1) At the ELAC1 receptacle, do a check of the resistance and of the
R insulation between the pin AD/2C and the pin AD/2D (15 to 250 ohms)
R (Ref. ASM 27-93/02).
R (a) If the resistance values are in the specified limits:
R - replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and
R (Ref. AMM TASK 27-93-34-400-001).
R (b) If the resistance is less than 15 ohms:
R 1_ Do the trouble shooting procedure (Ref. TASK 27-90-00-810-
R 801).
R 2_ Replace the ELAC-1 (2CE1) (Ref. AMM TASK 27-93-34-000-001) and
R (Ref. AMM TASK 27-93-34-400-001).
R (c) If the resistance is more than 250 ohms:
R 1_ Do a check and repair the wiring of the ACS2 signal from the
R ELAC1 MON side to the first terminal block (Ref. ASM 27-
R 93/02).
R 2_ Install the ELAC1 (Ref. AMM TASK 27-93-34-400-001).
R B. Do the test given in para. 3.
