R - If the resistance is less than 100 Megohms:

R  . Replace the SERVO CTL-L AILERON, INBD G (33CE1) (Ref.

R  AMM TASK 27-14-51-000-001) and (Ref. AMM TASK 27-14-51-400-001)

R . Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-R 001) and (Ref. AMM TASK 27-93-34-400-001).

R  2_ If the resistance is more than 100 Megohms:
R a_ Repair the wiring of the solenoid valve signal from theR SERVO CTL-L AILERON, INBD G (33CE1) to the ELAC-2 (2CE2)
R b_ Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001)R and (Ref. AMM TASK 27-93-34-400-001).
 B. Do the test given in Para. 3.

 Aug 01/00 CES Failure of the Right Green Aileron Servo Control Position Transducer

 1. Possible Causes
_______________
 - SERVO CTL-R AILERON, INBD G (33CE2)

 - wiring of the LVDT POS SPLY signal from the servo control (33CE2) to the first terminal block

 - wiring of the POS XDCR, V11, V12, V21, V22 signal from the servo control (33CE2) to the first terminal block

 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. Do a check for maintenance messages on the POST FLIGHT REPORT (PFR)
 (1) If there are these maintenance messages:
 R G AIL POS XDCR 33CE2
 L B AIL POS XDCR 33CE3

 - do this procedure (Ref. TASK 27-90-00-810-807).

 (2) If there is only this maintenance message:
 R G AIL POS XDCR 33CE2

 (a) Replace the SERVO CTL-R AILERON, INBD G (33CE2), (Ref. AMM TASK 27-14-51-000-001) and (Ref. AMM TASK 27-14-51-400-001).
 NOTE : The resistance of primary (pins A/B and A/C) and secondary
____ (pins A/A and A/P, pins A/R and A/D) 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.
 (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:

 1 Do a check of the wiring of the LVDT POS 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 POS XDCR, V11, V12,
_ V21, V22 signal from the servo control (33CE2) to the first terminal block, (Ref. ASM 27-93/02).
