## Discrepancy

FLIGHT DIVERTED DUE TO THE LOSS OF CABIN PRESSURE CONTROL.  AN EMERGENCY WAS DECLARED.  MAINTENANCE DISCOVERED THAT THE OUTFLOW VALVE WAS LEAKING BEYOND ALLOWABLE LIMITS AND PLACED IT ON MEL 21-00-25. THE OUTFLOW VALVE WAS REPLACED AND 2 OTHER FUSELAGE LEAKS WERE FOUND AND SEALED. THE ACFT HAS RETURNED TO SERVICE.
