R (7) Do the leak test of the standby Air Data system (Ref. AMM TASK 34-22-R 25-790-001).
R (8) Do the functional test of the ADM for the CAPT (F/O) circuit (Ref.
R 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-R 001).
R (9) If the fault continues:
R - If there is a report of small airspeed/altitude fluctuations and if
R there are maintenance messages related to the SFCCs in the PFR :
R replace the defective SFCCs (Ref. AMM TASK 24-51-34-000-001) and
R (Ref. AMM TASK 27-51-34-400-001)
R - Do a check of the ADR/SFCC interface wirings (Ref. ASM 34-13/02).
R - Do a check to make sure that there are no impacts on the fuselage
R around the ADMs and the static probes (Ref. SRM 530011P.BLOCK101).
