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).

R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299, 401-499,
A. Do a check for maintenance messages on the POST FLIGHT REPORT (PFR)
(1) If there are these maintenance messages:
R G AIL MODE XDCR 33CE2 OR INPUT OF ELAC1
L B AIL MODE XDCR 33CE3 OR INPUT OF ELAC1
- do this procedure (Ref. TASK 27-90-00-810-809).
(2) If there is only this maintenance message:
R G AIL MODE XDCR 33CE2 OR INPUT OF ELAC1
(a) Replace the ELAC-1 (2CE1), (Ref. AMM TASK 27-93-34-000-001) and (Ref. AMM TASK 27-93-34-400-001).
(b) On the panel 23VU, release and push the FLT CTL/ELAC 1 pushbutton switch.
(c) On the EWD, if the F/CTL AIL SERVO FAULT warning stays in view:
- replace the MODE XDCR of the servo control (33CE2), (Ref. AMM TASK 27-14-51-000-005) and (Ref. AMM TASK 27-14-51-400-005).
NOTE : The resistance of primary (pins A/K and A/L) and secondary
____ (pins A/J and A/U) windings of the transducer must be between 30 ohms and 500 ohms. The insulation must be more than 100 Mohms. These values are given for information only. You can use these values to do checks of the component electrical part or of the wiring before you replace the component. But by this procedure, the check of the component mechanical part is not done. For primary winding (power supply):
- if you do the resistance check from the avionics compartment, you must disconnect the transducer of the Left Blue Aileron Servo Control.
(d) On the panel 23VU, release and push the FLT CTL/ELAC 1 pushbutton switch.
(e) On the EWD, if the F/CTL AIL SERVO FAULT warning stays in view:
1 Do a check of the wiring of the MODE XDCR SPLY signal from the
_ servo control (33CE2) to the first terminal block, (Ref. ASM 27-93/02):
- if there is no continuity, repair the wiring
- if there is continuity, see Para. 2_.
2 Do a check and repair the wiring of the MODE XDCR VS1, VS2
_ signal from the servo control (33CE2) to the ELAC 1 (2CE1), (Ref. ASM 27-93/02).
R **ON A/C 301-399,
R A. Procedure
R (1) If the test gives these maintenance messages:
R R G AIL MODE XDCR 33CE2 OR INPUT OF ELAC1
R L B AIL MODE XDCR 33CE3 OR INPUT OF ELAC1
R - do this procedure (Ref. TASK 27-90-00-810-809).
R (2) If the test gives only this maintenance message: R R G AIL MODE XDCR 33CE2 OR INPUT OF ELAC1
R (a) 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) On the panel 23VU, release and push the FLT CTL/ELAC 1 pushbutton R switch.
R (c) On the EWD, if the F/CTL AIL SERVO FAULT warning stays in view: R - replace the MODE XDCR of the servo control (33CE2), (Ref. AMM R TASK 27-14-51-000-005) and (Ref. AMM TASK 27-14-51-400-005).
R NOTE : The resistance of primary (pins A/K and A/L) and secondary
