## Discrepancy

DURING THE FLIGHT, WITH ONE AIR CONDITIONING PACK ON MEL, THE CREW RECEIVED ECAM WARNING 'AIR L WING LEAK'.  THEN CREW RECEIVED ECAM WARNING 'AIR R WING LEAK'.  THE AIRCRAFT BEGAN TO DEPRESSURIZE.  AN EMERGENCY DESCENT WAS MADE.  THE FLIGHT DIVERTED TO MCI AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REPLACED THE NR 1 FLOW CONTROL VALVE AND SEALS IN THE PACK BAY.  OPERATIONALLY AND LEAK CHECKED OK.
