 AOA ref = PITCH - FPA
 For the 12 selected snapshots in the report, calculate AOAref.
 3_ For each snapshot compare the AOAref with the 3 AOA values
 (AOA1, AOA2, AOA3) and make sure that the difference does not
 exceed the tolerances below:
 . (AOA1 - AOAref) is less than or equal plus or minus 0.5 deg.
 . (AOA2 - AOAref) is less than or equal plus or minus 0.5 deg.
 . (AOA3 - AOAref) is less than or equal plus or minus 0.5 deg.

 (b) Conclusion Remove the Angle of Attack sensor that exceeds these tolerances (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).

 B. If you cannot start the test of the angle of attack sensor 1 on the MCDU:
 - replace the ADIRU-1 (1FP1) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
 (1) If the fault continues:
 - replace the RELAY-AOA 1 TEST (21FP1)
 (a) If the fault continues:
 - do a check of the wiring of the AOA 1 TEST relay (21FP1): . from pin A/A to the first terminal block . from pin A/X to the first terminal block . from pin A/Z to ADIRU1 (1FP1) pin AA/12G . from pin A/2 to angle of attack sensor 1 (3FP1) pin A/X (Ref. ASM 34-11/02).
 1 If there is no continuity:
_ - repair the above wiring.
 2 If there is continuity:
_
 - do a check of the wiring of the ground signal at angle of attack sensor 1 (3FP1) pin A/V (Ref. ASM 34-11/02).
 a If there is no continuity:
_ - repair the above wiring.
 b If there is continuity:
_
 - 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).
