Incident Details
The takeoff was attempted from a runway contaminated with snow windrows. The twin-engine airplane experienced instability during the takeoff roll. In response, the pilot decided to lift off prematurely.
Sequence of Events
After the premature lift-off, the aircraft stalled. It then collided with a snow bank and crashed, resulting in a fire.
Injuries and Damage
All four occupants on board were injured. Two of them sustained serious injuries. The aircraft was destroyed by impact and fire.
Probable Cause
The official investigation determined the probable cause to be a stall during initial climb after the pilot failed to maintain directional control. Contributing factors included the pilot's failure to abort the takeoff, failure to maintain flying speed, premature lift-off, snow on the runway, and snow windrows.
