- replace the SENSOR-ANGLE OF ATTACK, 2 (3FP2) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(2) If the angle of attack sensor 2 (3FP2) is not damaged:
- no other action is neccesary.
(a) After the subsequent flight, if the fault continues:
- replace the SENSOR-ANGLE OF ATTACK, 2 (3FP2).
B. If the maintenance message AOA SENSOR2 (3FP2)/ADIRU2 (1FP2) is shown in the Ground Scanning, after the test of the angle of attack warning:
- no maintenance action is necessary.
NOTE : At the end of the test, on the ADIRS CDU, set the OFF/NAV/ATT
____ selector switch related to the ADIRU2 to OFF for some seconds then to NAV to cancel the messages (fast re-alignment is not sufficient)

_______________
A. If the air data indications go out of view on the CAPT PFD with the AIR DATA selector switch at CAPT/3:
- remove the DMC1 and DMC3 (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
- do a check for a ground signal at the pin AB/4E of the DMC1 and DMC3.
(1) If there is no ground signal:
- replace the SEL SW-AIR DATA (15FP).
(a) If the fault continues:
- do a check and repair the wiring of the AIR DATA selector switch (15FP): pin A/5 to the ground point pin A/6 to the first terminal block (Ref. ASM 31-68/04).
