The pilot cleaned snow off the airplane. However, under the snow, 80% of the airplanes wing was covered with a coarse layer of ice from 1/16 inch (1,6 mm) to 3/16 inch (4,8 mm) thickness that was not removed. The airplane departed from runway 35L, intersection Foxtrot, at 09:01. During the instrument departure climbing turn, at 400 feet above the ground, the engine surged and lost power. The aircraft began to lose altitude and the pilot landed in a snow covered flat field of winter wheat. The engine was broken from its mounts and forced under the airplane on the pilot's side and the belly pod was crushed on first impact.
PROBABLE CAUSE: "The pilot's failure to remove ice from the airframe prior to takeoff. Factors were freezing rain the night before and the pilots' incomplete preflight inspection."
