(5) Do the functional test of the ADM for the CAPT (F/O) circuit (Ref. AMM TASK 34-11-00-720-001).
(a) If one pressure value is different, replace the defective ADM (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
(b) If the pressure values are the same, replace the AOA sensor 1(2) (3FP1(2)) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(6) If the fault continues:
- Do a check to make sure that there are no impacts on the fuselage around the AOA sensors, the static probes and the ADMs (Ref. SRM 530011P.BLOCK101).
B. If the test shows a different altitude value from the ADR3 (compared to the ADR1 and the ADR2):
- do a visual check of the static probes.
R (1) If one static probe is damaged, replace it (Ref. AMM TASK 34-11-16-R 000-001) and (Ref. AMM TASK 34-11-16-400-002).
(2) Make sure that the small wing of the AOA sensor 3 (3FP3) is not damaged and that the mechanism moves freely.
R (a) If the AOA sensor 3 (3FP3) is damaged, replace it (Ref. AMM TASK R 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(b) If the AOA sensor 3 (3FP3) is not damaged:
- do the ADIRS start procedure (Ref. AMM TASK 34-10-00-860-002)
- connect the ARINC Reader to the test connector 199VC on the panel 187VU (Ref. ASM 34-13/01)
- manually turn the AOA sensor 3 (3FP3) to the down position
- manually turn the AOA sensor 3 (3FP3) to the up position
- compare the AOA values (between -35 deg. and -34.5 deg. for the down position and between +84.5 deg. and +85 deg. for the up position) read on label 221:
ADIRU 3 199VC 3FP3 pins y, z

- replace the AOA sensor 3 (3FP3) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(3) Do the draining and flushing of the standby static and the standby total pressure line of the Air Data Module (19FP8) (Ref. AMM TASK 34-10-00-170-003).
(4) Do the leak test of the standby circuits (Ref. AMM TASK 34-21-00-790-001).
