## Discrepancy

THE CREW REPORTED CRUISING AT FL320 FELT A PRESSURE BUMP.  NO EICAS WARNING BUT CABIN ALT BOX AMBER AND QUICKLY STARTED TO CLIMB. CLIMBED TO ABOUT 12000 FT.  THE CREW RAN A RAPID CABIN DEPRESSURAZTION AND EMERGENCY DESCENT.  DECLARED EMERGENCY AND DESCENDED TO 10,000FT.  SHORTLY THERE AFTER, PRESSURIZATION STARTED WORKING. CABIN ALT WENT FROM 10,000 TO 2,000.  LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE R & R CPAM, DIGITAIL CONTROLLER, AND ELECTO PNEUMATIC OUTFLOW VALVE.  OPS CHECKS WERE GOOD.
