## Discrepancy

CREW REPORTS AVIONICS SYSTEM FAULT.  EXTRACT VALVE SHOWING CLOSED.  AIRCRAFT WAS INDICATING FAULTS FOR BOTH THE SKIN AIR INLET AND OUTLET VALVES WITH THE OUTLET VALVE DEFERRED INOPERATIVE.  THE SYSTEM WAS REACTIVATED ON THE GROUND AND THE FAULT WAS ISOLATED TO THE INLET VALVE.  THE OUTLET VALVE DEFERRAL WAS CLEARED DUE TO THE SUCCESSFUL GROUND TESTING AND TROUBLESHOOTING, AND THE INLET VALVE WAS SUBSEQUENTLY REPLACED WITH NO FURTHER FAULTS REPORTED.
