## Discrepancy

THE FLIGHT CREW REPORTED OF A DOOR SEAL ANNUNCIATOR ILLUMINATED DURING CRUISE FLIGHT. THE CREW DESCRIBED THAT THE DOOR SEAL LEAK COULD BE HEARD AND DAY LIGHT COULD BE SEEN ON THE AFT SIDE ABOUT KNEE HIGH. BECAUSE OF THE DOOR SEAL LEAK AND THE DOOR SEAL ANNUNCIATOR THE CREW ELECTED TO DIVERT FLIGHT AND LAND. THE MAINTENANCE VENDOR CHECKED THE PRIMARY DOOR SEAL FOR LEAKS AND DAMAGE BUT NONE WERE NOTED. DOOR SEAL INFLATION CHECKS WAS SATISFACTORY. NO FAULTS WERE FOUND AND THE AIRCRAFT WAS RETURNED TO SERVICE.
