Incident Overview
A pilot initiated a takeoff while snow and ice remained on the aircraft. During the takeoff roll, the aircraft became airborne for a short period before settling back onto the runway. In response, the pilot attempted to abort the takeoff. The aircraft continued beyond the runway end, where it struck navigation antennas and rough terrain. All four occupants exited the aircraft without injury.
Sequence of Events
The takeoff was commenced with snow and ice present on the aircraft's surfaces. As the aircraft accelerated, it lifted off the runway briefly but then descended and contacted the runway again. The pilot then decided to abort the takeoff. However, the aircraft was unable to stop before the runway's end, departing the prepared surface and impacting navigation antennas and uneven ground.
Occupant Status
All four individuals aboard the aircraft escaped without any reported injuries.
Official Probable Cause
The investigation determined the probable cause to be the pilot's inadequate preflight preparation of the aircraft, his failure to remove snow and ice from the aircraft before takeoff, and his delay in attempting to abort the takeoff.
