_______________
A. If the test gives the maintenance message AOA SENSOR1 (3FP1):
- do a check for 26VAC at pins A/A,M of the angle of attack sensor 1 (3FP1).
(1) If there is 26VAC:
- 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).
(2) If there is no 26VAC:
- do a check for a ground signal at pins A/B,N of the angle of attack sensor 1 (3FP1).
(a) If there is no ground signal:
- repair the wiring from angle of attack sensor 1 (3FP1) pins A/B,N to the ground terminal (Ref. ASM 34-11/01).
