_______________
R A. If the conditions which follow occur:
R - the POST FLIGHT and/or the LAST LEG REPORT gives the maintenance
R message AFT TRIM AIR VALVE and,
R on the lower ECAM display unit COND page the AFT trim-air valve
R position shows amber XX:
R

 - replace the VALVE-TRIM AIR, AFT CARGO COMPT (12HC) (Ref. AMM TASK 21-43-51-000-001) and (Ref. AMM TASK 21-43-51-400-001).

 (1) If the fault continues:

 - do a check and repair the wiring (Ref. ASM 21-43/02) from:

 - the VALVE (12HC) to the ACHC (10HC) and,

 - the VALVE (12HC) to ground.

 (2) If the fault continues:

 - replace the CONT-CARGO HEAT (10HC) (Ref. AMM TASK 21-43-34-000-002) and (Ref. AMM TASK 21-43-34-400-002).
 B. Do the test as given in the Para. 3.A.
