- 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.
 (1) If one static probe is damaged, replace it (Ref. AMM TASK 34-11-16-000-001) and (Ref. AMM TASK 34-11-16-400-002).

 (2) Make sure that the small wing of the AOA3 sensor is not damaged and that the mechanism moves freely.

 (a) If the AOA sensor 3 is damaged, replace it (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).

 (5) Do the functional test of the ADM for the standby 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 3 (3FP3) (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 sensor 3, the ADMs and the static probes (Ref. SRM 530011P.BLOCK101).

 C. If the test shows a different airspeed value from the ADR1 (compared to the ADR2 and the ADR3), from the ADR2 (compared to the ADR1 and the ADR3) or from the ADR3 (compared to the ADR1 and the ADR2):
 (1) Do the Operational Test of the probe ice protection (Ref. AMM TASK 30-31-00-710-001).

 (a) If the test gives a maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.

 (2) Do the Interface test of the ADR (Ref. AMM TASK 34-13-00-740-002).

 (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).

R  (a) If one pressure value is different, replace the defective ADM
R  (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).

 D. Do the test given in Para. 3.
