## Discrepancy

THE EMERGENCY OXYGEN MASK FOR THE FLIGHT ATTENDANT'S AFT JUMPSEAT DID NOT DEPLOY WHEN ALL OTHER PASSENGER MASKS DID DURING AN EMERGENCY DESCENT DUE TO LOSS OF CABIN PRESSURIZATION.  THE MASK FINALLY DEPLOYED AFTER THE AIRCRAFT LEVELED OFF AT 10,000 FEET.  MAINTENANCE REPACKED ALL MASKS AND PERFORMED A FUNCTIONAL CHECK OF THE DEPLOYMENT SYSTEM.  OPERATIONAL CHECK GOOD AND ALL MASKS DEPLOYED.  AIRCRAFT RETURNED TO SERVICE.
