 A. If the test gives the maintenance message AOA SENSOR1 (3FP1)/ ADIRU1 (1FP1):
 - replace the SENSOR-ANGLE OF ATTACK, 1 (3FP1) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
 (1) If the fault continues:
 - replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring from the angle of attack sensor 1 (3FP1) to the AOA INPUTS 1 and 2 of the ADIRU 1 (1FP1) (Ref. ASM 34-11/02).

 B. If the test is OK, do a visual inspection of the angle of attack sensors:
 (1) If an angle of attack sensor is found damaged:

 - replace the angle of attack sensor.

 (2) If no external damage is found:

 - keep the angle of attack sensor on the aircraft.

 (3) If no external damage is found but the message is shown again:

 - replace the angle of attack sensor.
 (4) Reset the ADIRU (NAV-OFF-NAV) to clear the ECAM message. **ON A/C ALL
 C. Do the test given in Para. 3.

 Loss of the AOA 2 Input to the ADR 2
 1. Possible Causes
_______________
 - SENSOR-ANGLE OF ATTACK, 2 (3FP2)

 - ADIRU-2 (1FP2)

 - wiring from the angle of attack sensor 2 (3FP2) to the AOA INPUTS 1 and 2 of the ADIRU 2 (1FP2)
