_______________
A. If the fault symptom is identified by the crew observation, ADIRS - TAT reading error of 11 deg. C on the lower ECAM DU:
(1) With the AIR DATA selector switch (15FP) and the ECAM/ND XFR selector switch (19WT) in the NORM positions:
- replace the PHC-2 (6DA2) (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
(a) If the fault continues:
- do a check and repair the wiring between the PHC2 and the ADIRU2 for pin AA/4F of the ADIRU2 (Ref. ASM 34-13/02).
(2) With the AIR DATA selector switch (15FP) in the NORM position and the ECAM/ND XFR selector switch (19WT) in the F/O position:
- do a check and repair the wiring between the ADIRU1 and the first terminal block for pin AA/4F of the ADIRU1 (Ref. ASM 34-13/02).

(3) With the AIR DATA selector switch (15FP) in the CAPT/3 position and the ECAM/ND XFR selector switch (19WT) in the F/O position:
- do a check and repair the wiring between the ADIRU3 and the first terminal block for pin AA/4F of the ADIRU3 (Ref. ASM 34-13/02).
(4) With the AIR DATA selector switch (15FP) in the NORM and CAPT/3 positions and the ECAM/ND XFR selector switch (19WT) in the F/O position:
- replace the PHC-1 (6DA1) (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
(a) If the fault continues:
- do a check and repair the wiring between the PHC1 and the first terminal block for pin AA/<A of the PHC1 (Ref. ASM 34-13/02).
