During takeoff from a snow-covered runway, a multi-engine airplane lost directional control. Despite reducing power on the right engine, the aircraft overran and came to rest in snow. The pilot was seriously wounded, and all four passengers were injured. The aircraft was destroyed.

Incident Overview

During takeoff from a snow-covered runway, the airplane became unstable and the pilot lost directional control. In an attempt to correct the skid, the pilot reduced power on the right engine, but this action was insufficient to regain control. The aircraft subsequently overran the runway and came to rest in a snow-covered area.

Injuries and Damage

All four passengers sustained injuries, and the pilot was seriously wounded. The aircraft was written off due to the damage sustained in the overrun.

Probable Cause (Official Findings)

The investigation determined that the loss of control during takeoff resulted from the pilot selecting an unsuitable terrain for takeoff. The following contributing factors were reported:

  • Snow on the runway
  • Delayed action in aborting the takeoff
  • Inadequate preflight preparation
  • Snow
  • Unfavorable wind conditions
  • Overload failure
  • Reduced power on the right engine to correct the skid
  • Unable to obtain takeoff speed and overrun the runway
