Accident Sequence
Witnesses observed the aircraft on final approach with its landing gear extended. The nose then pitched up, the aircraft rolled left, and it subsequently crashed into trees. A post-impact fire destroyed the cockpit, cabin, engine nacelles, cargo, and portions of the wings.
Post-Accident Examination
Examination of the wreckage revealed that the landing gear was in the up and locked position, and the flaps were set at 30°. This configuration is consistent with a go-around maneuver. No mechanical malfunctions or failures were identified.
Aircraft and Pilot Information
The aircraft held a restricted category airworthiness certificate. The cargo area contained two fuel tanks, an oil stove, tools, a 55-gallon drum, and hoses. The pilot was type-rated in the aircraft.
Runway Conditions
The runway length listed in the Alaska supplement was 1,000 feet longer than the actual runway length. The runway surface was glazed with ice.
Occupants
Both occupants were killed.
Official Findings
The probable cause findings cited by the investigation include: improper in-flight planning/decision by the pilot in command, improper airspeed, inadvertent stall, inadequate altitude, and an attempted go-around, leading to loss of control in flight and subsequent collision with terrain.
