Accident Overview
According to witness statements, the pilot of the accident airplane attempted a formation takeoff with another aircraft. Both airplanes were observed to begin their takeoff roll and lift off from the same runway simultaneously.
Sequence of Events
During the takeoff roll, the pilot of the accident airplane prematurely lifted off at an airspeed that was not adequate to sustain flight. The airplane subsequently experienced an aerodynamic stall at about 50 feet above the runway. It then impacted snow-covered terrain off the edge of the runway.
Damage and Examination
The airplane sustained substantial damage as a result of the impact. No preimpact mechanical deficiencies were reported.
Probable Cause
The probable cause of this accident was the pilot's premature liftoff at an airspeed inadequate to sustain flight.
