(a) if the test gives a maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
(3) do a visual check of the pitot probes. R - If one pitot probe is damaged, replace it (Ref. AMM TASK 34-11-15-R 000-001) and (Ref. AMM TASK 34-11-15-400-001).
(4) Do the flushing of the total pressure line of the ADM (19FP1, 19FP2, 19FP3) (Ref. AMM TASK 34-10-00-170-001).
(5) Do the leak test of the main Air Data system (Ref. AMM TASK 34-13-00-790-002).
(6) 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).
(7) If the fault continues:
- If there is a report of small airspeed/altitude fluctuations and if there are maintenance messages related to the SFCCs in the PFR : replace the SFCCs.
- Do a check of the ADR/SFCC interface wirings (Ref. ASM 34-13/02).
- Do a check to make sure that there are no impacts on the fuselage around the ADMs and the static probes (Ref. SRM 530011P.BLOCK101).

R **ON A/C 213-213, 221-228,
R B. If the test shows a different altitude value from the ADR3 (compared to
R the ADR1 and the ADR2):
R - 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).
R (2) Make sure that the small wing of the AOA3 sensor is not damaged and
R that the mechanism moves freely.
R (a) If the AOA sensor 3 is damaged, replace it (Ref. AMM TASK 34-11-R 19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
R (3) Do the draining and flushing of the standby static and the standby
R total pressure line of the Air Data Module (19FP8) (Ref. AMM TASK 34-R 22-25-170-001).
R (4) Do the leak test of the standby circuits (Ref. AMM TASK 34-22-25-790-R 001).
R (5) Do the functional test of the ADM for the standby circuit (Ref. AMM
R TASK 34-11-00-720-001).

R (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-R 001).
R (b) If the pressure values are the same, replace the AOA sensor 3
R (3FP3) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-R 19-400-001).
R (6) If the fault continues:
R - Do a check to make sure that there are no impacts on the fuselage
R around the AOA sensor 3, the ADMs and the static probes (Ref. SRM
R 530011P.BLOCK101).
R C. If the test shows a different airspeed value from the ADR1 (compared to
R the ADR2 and the ADR3), from the ADR2 (compared to the ADR1 and the ADR3)
R or from the ADR3 (compared to the ADR1 and the ADR2):
R (1) Do the Operational Test of the probe ice protection (Ref. AMM TASK
R 30-31-00-710-001)
R (a) if the test gives a maintenance message, you can find the related
R trouble shooting procedure in the applicable Page Block 101.
