Accident Details
An airline transport pilot was conducting a departure from a soft, snow-covered frozen lake in a wheel/ski-equipped airplane. The flight was in support of a sled dog race and carried one passenger along with cargo. According to the pilot, wind conditions at the time included gusts up to 20 knots with variable direction.
Sequence of Events
Shortly after takeoff, while executing a slight left turn, the airplane descended near the departure end of the lake and subsequently impacted snow-covered terrain. The impact caused the airplane to nose over, resulting in substantial damage to both wings and the fuselage.
