Aircraft Accident/Incident Report

Big Lake, Alaska 99652
Saturday, January 22, 2005 12:30 AST

NTSB Narrative Summary Released at Completion of Accident

The private pilot reported that he had landed on the frozen lake about an hour before the accident occurred. He said that the surface of the frozen lake was smooth and covered by about 2 inches of fresh snow, and that "flat light conditions" made it very difficult to discern any topographical features on the lake ice. The pilot reported that as he taxied the airplane in preparation for takeoff, it began to slide on the snow-covered ice, and he applied engine power in an attempt to gain effective rudder control. He said that as the airplane gained speed on the ice, the main landing gear wheels struck a large ice ridge, and the airplane was "pitched into the air." The pilot said that in an attempt to land the airplane and regain control, he closed the throttle, and the airplane descended rapidly. The airplane's main wheels struck the lake, and the left main landing gear partially collapsed. The airplane subsequently veered to the left, struck a stand of trees on the left side of the lake, and sustained substantial damage to the wings and fuselage.

NTSB Probable Cause Narrative

The pilot's selection of an unsuitable takeoff/landing/taxi area, which resulted in an on-ground encounter with a berm, a loss of control on the ground, and collapse of the main landing gear. Factors associated with the accident were flat light conditions, and a berm.
