## Discrepancy

AFTER TAKEOFF AND CLIMBING TO ALTITUDE, THE CREW HEARD A LOUD AIR LEAK COMING FROM THE MAIN CABIN DOOR. CREW FOLLOWED THE EMERGENCY CHECK LIST PROCEDURES AND DESCENDED.  CREW CHOSE TO DIVERT FOR MAINTENANCE.  MFG MX PRESSURIZED ACFT AND FOUND A LEAK NEAR THE DOOR HINGE AREA. THIS AREA WAS CLEANED AND REPAINTED TO ACHIEVE A GOOD MATING SURFACE FOR THE DOOR SEAL.  MX PRESSURIZED ACFT AGAIN AND HAD NO LEAKS.  ACFT WAS RETURNED TO SERVICE.
