## Discrepancy

LOSS OF CABIN PRESSURE OCCURRED DURING CRUISE FLIGHT ENROUTE MEM-MIA.  CABIN ALTITUDE REACHED 11,000 FEET AND CAPTAIN DECLARED AN EMERGENCY.  OXYGEN MASKS WERE DEPLOYED THROUGHOUT CABIN.  PRESSURIZATION WAS REGAINED THROUGH MANUAL CONTROL AND FLIGHT CONTINUED TO DESTINATION WITHOUT FURTHER INCIDENT.  REPLACED CABIN PRESSURE CONTROLLER AND AMPLIFIER.  OPERATIONAL CHECK OK.  AIRCRAFT RETURNED TO SERVICE.
