- CAB PR OUTFLOW VALVE NOT OPEN and a visual inspection of the outflow valve shows that it is open, then:
- replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(2) If the fault continues:
- replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(3) If the fault continues:
- replace the Outflow Valve Feedback-Assembly 10HL6 (Ref. AMM TASK 21-31-51-000-005) and (Ref. AMM TASK 21-31-51-400-005).
(4) If the fault continues:
- do a check and repair the wiring between the:
- OFV connector (10HL-D) pin F and the CPC connector (11HL-AB) pin 1D.
- OFV connector (10HL-D) pin G and the CPC connector (11HL-AB) pin 2D.
- OFV connector (10HL-D) pin H and the CPC connector (11HL-AB) pin 3D (Ref. ASM 21-31/01) (Ref. ASM 21-31/03).
(5) If the fault continues:
- replace the CONTROLLER-CABIN PRESSURE 1 (11HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
B. Test Results
NOTE : This procedure is only applicable for:
____ - Outflow Valve Part Number 20790-01AA and onwards.
(1) If the POST FLIGHT REPORT gives the maintenance message:
- CAB PR OUTFLOW VALVE NOT OPEN and a visual inspection of the outflow valve shows that it is open, then:
- replace the SDAC-1 (1WV1) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
(2) If the fault continues:
- replace the SDAC-2 (1WV2) (Ref. AMM TASK 31-55-34-000-001) and (Ref. AMM TASK 31-55-34-400-001).
