Accident
During final approach to an airport, approximately 1.5 miles from the runway, the pilot experienced a loss of engine power while attempting to add power. The aircraft flew over a ridge and several trees before touching down in rough terrain. After coming to rest, a fire erupted. Witnesses reported no signs of fire until the aircraft had stopped.
Investigation
Examination of the aircraft and engine revealed that three fuel injectors on the left bank were blocked with a substance later identified as primarily dirt. The fire appeared to have originated in the vicinity of the fuel strainer and spread rearward. Both occupants were able to exit the aircraft unharmed.
Probable Cause
The official finding states that the reason for the loss of engine power is undetermined.
