A. If the POST FLIGHT REPORT gives the NAV ADR3 FAULT ECAM warning:
- do a check of the status of the ADR3 pushbutton switch on the ADIRS CDU.
(1) If the pilot pushed the ADR3 pushbutton switch during the flight:
- no maintenance action is necessary.
(2) If the pilot did not push the ADR3 pushbutton switch during the flight:
- remove the ADIRU-3 (1FP3) (Ref. AMM TASK 34-12-34-000-001)
- remove the CDU-ADIRS (2FP) (Ref. AMM TASK 34-12-12-000-001)
- do a check for a short to ground on the wiring between the ADIRS CDU (2FP) and the ADIRU3 (1FP3) between pin C/9 of the ADIRS CDU and pin AA/4C of the ADIRU3 (Ref. ASM 34-13/02).

_______________
A. If the fault symptom is identified by the observation that follows: Different true airspeed indication between CAPT and F/O ND:
- do the functional test of the altitude and airspeed data (Ref. AMM TASK 34-13-00-720-009).
(1) If the test gives a different altitude value and/or 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):
