## Discrepancy

SHV - AIRCRAFT N15980 WAS GIVEN A FERRY FLIGHT RELEASE PERMIT FROM DFW TO SHV BECAUSE PACK VALVE 1 CLOSED, COULD NOT RESET.  CABIN ALT RAISED PASSED 8,000FT UP TO 14,000FT AT 14:00.  EMERGENCY DESCENT WAS PERFORMED.  ALSO, O2 MASKS DEPLOYED COMING OUT OF OKC.  MAINTENANCE IN SHV PERFORMED OPERATIONAL CHECK OF PACK 1 VALVE IAW EMB145 AMM 21-31-00.  OPERATIONAL CHECK GOOD.  PRESSURIZATION CHECK PASSED.  THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
