## Discrepancy

CLIMBING THROUGH FL 300, THE FLIGHT CREW WITNESSED THE RT ENG FIRE WARN LIGHT ILLUMINATE. FOLLOWING CHECKLIST PROCEDURES, THE LIGHT WENT OUT AFTER 15-20 SECONDS, AND REMAINED OUT.  AN UNSCHEDULED LANDING WAS MADE AT THE DEPARTURE AIRPORT. INSPECTION BY MAINTENANCE PERSONNEL REVEALED THAT THE LP TO MOD VALVE CONNECTION WAS LEAKING BLEED AIR. THE SEAL WAS REPLACED, LEAK CHECK PERFORMED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
