Aircraft Accident/Incident Report

Troy, Michigan 48084
Friday, July 16, 1999 18:00 EDT

NTSB Narrative Summary Released at Completion of Accident

The pilot heard two loud backfires or explosions during the right engine start. He saw an area of the right wing expanded upward. The passenger saw flames coming from the right wing. The pilot shut down both engines. Two observers fought the fire with extinguishers. The pilot and passenger evacuated the airplane. The fire department chief said that a 'couple hundred foot' column of black smoke was observed and the response time was four to five minutes. He said the airplane was facing north, the wind was coming from the west, and the wind blew the flames away from the fuselage. He said the right wing outboard of the engine nacelle was on the ground with some wiring and some melted structure present between the nacelle and the wing. The tops of the wing and tip tank were melted and flames were observed coming out from the melted areas and from the nacelle area. Inspectors at the scene were unable to determine the source of the fire. The airplane records were reviewed and they did not reveal any anomalies.

NTSB Probable Cause Narrative
