Loss of the ADM BUS 3 Input Data to the ADIRU 2
 1. Possible Causes
_______________
 - ADM-R STATIC PRESSURE (19FP6)

 - ADIRU-2 (1FP2)

 - wiring of the ADM BUS 3 INPUT bus from the R static pressure ADM (19FP6) to the ADIRU 2 (1FP2)

 A. Test Do the Interface test of the ADR (system 2) (Ref. AMM TASK 34-13-00-740-002).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message ADM6 (19FP6)/ADIRU2 (1FP2):
 - replace the ADM-R STATIC PRESSURE (19FP6) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
 (1) If the fault continues:
 - replace the ADIRU-2 (1FP2) (Ref. AMM TASK 34-12-34-000-001) and (Ref. AMM TASK 34-12-34-400-001).
 (a) If the fault continues:
 - do a check and repair the wiring of the ADM BUS 3 INPUT bus from the R static pressure ADM (19FP6) to the ADIRU 2 (1FP2) (Ref. ASM 34-13/03).
 B. Do the test given in Para. 3.
