Loss of the AOA 2 Input to the ADR 2


TASK 34-13-00-810-907-A
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)

Subtask 34-13-00-740-213-A
A. Test
Do the Interface test of the ADR (system 2) AMM 34-13-00-740-002.
4. Fault Isolation
Subtask 34-13-00-810-156-B
A. If the test gives the maintenance message AOA SENSOR2 (3FP2)/ ADIRU2 (1FP2):
   (1) If the fault continues:
     (a) If the fault continues:
  • do a check and repair the wiring from the angle of attack sensor 2 (3FP2) to the AOA INPUTS 1 and 2 of the ADIRU 2 (1FP2) ASM 341102.
Subtask 34-13-00-810-255-A ** ON A/C NOT FOR ALL
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.
Subtask 34-13-00-740-214-A
C. Do the test given in Para. 3.
