Standiford Field Airport
Aircraft Accident/Incident Report

Louisville, Kentucky 40213
Saturday, September 4, 2004 16:30 EDT

NTSB Narrative Summary Released at Completion of Accident

Upon landing at the destination airport, the pilot was informed that he would have to pay a ramp and parking fee, or buy a minimum of 15 gallons of fuel. Even though the airplane would not require any additional fuel for the subsequent flight, the pilot opted to buy fuel to avoid paying the fees. While the refueler was servicing the left auxiliary fuel tank, he allowed between 1 and 5 gallons to overflow. About 15 minutes later, the pilot attempted to start the left engine, and simultaneously, an explosion occurred in the left wing. The engine did not start, but the pilot thought that it backfired at the time of the explosion. Examination of the left wing revealed damage consistent with an internal explosion, and that the fuel cells were intact, full of fuel, and not leaking.

NTSB Probable Cause Narrative

The improper refueling of the left auxiliary fuel tank, which resulted in an overflow of fuel, and a subsequent explosion in the left wing during engine start.
