Loss of the ADM BUS 1 Input Data to the ADIRU 1
 1. Possible Causes
_______________
 - ADM-L TOTAL PRESSURE (19FP1)

 - ADIRU-1 (1FP1)

 - wiring of the ADM BUS 1 INPUT bus from the L total pressure ADM (19FP1) to the ADIRU 1 (1FP1)

 A. Test Do the Interface test of the ADR (system 1) (Ref. AMM TASK 34-13-00-740-002).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message ADM1 (19FP1)/ADIRU1 (1FP1):
 - replace the ADM-L TOTAL PRESSURE (19FP1) (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-1 (1FP1) (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 1 INPUT bus from the L total pressure ADM (19FP1) to the ADIRU 1 (1FP1) (Ref. ASM 34-13/03).
 B. Do the test given in Para. 3.
