Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

While the aircraft was in cruise flight at flight level 400, the right wing overheat light illuminated. The crew accomplished the appropriate checklist, and then about five minutes later the engine number three and engine number four B fire loop indicators illuminated. Soon thereafter an acrid odor was detected by the flight crew, and smoke was seen coming from behind the P-6 circuit breaker panel. The crew then became aware of a small fire in the fire detection card file, which they extinguished with a hand-held fire extinguisher. The crew then diverted to a nearby airport and completed an uneventful precautionary landing. The post-event investigation revealed that the fire detection card for engine number four B Loop fire detection (card A16), and its associated socket connector, had suffered severe thermal damage to include partial destruction. A series of tests and examinations were not able to detect evidence of any specific anomalies in the A16 card, the card file, the card file protection circuit, or any of the aircraft's systems. There was no evidence of a lightning strike being the initiating event, and the aircraft has continued in service since the time of this event without generating any other maintenance discrepancies known to be directly related to the fire detection card files.

NTSB Probable Cause Narrative

An undetermined malfunction in an aircraft system while in cruise flight leading to a fire in the engine number four B Loop portion (Card A16) of the fire detection controls cardfile.
