Runway and Conditions
The runway was a 3,000-foot gravel strip covered with hard packed snow. Snow berms were present on both sides of the runway.
Sequence of Events
The pilot reported breaking ground approximately halfway down the runway at an airspeed of about 50 knots. After reaching an altitude of about 40 feet above ground level, the pilot observed that the aircraft was drifting toward 60-foot trees located on the right side. In response, the pilot banked the aircraft to the left and increased pitch. Subsequently, the left wing dropped, and the aircraft descended until it impacted the runway. The aircraft came to rest approximately 300 feet from the far end of the runway.
Injuries
The two occupants in the front seats sustained serious injuries. A third occupant seated in the rear was not injured.
