Probable cause

The pilot's selection of terrain that was rough, snow-covered and icy for takeoff.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

The pilot stated that, during the takeoff on the frozen lake, he encountered very rough surface conditions which did not allow the airplane to reach liftoff speed. During the aborted takeoff, the pilot encountered an area of very slick snow-covered ice. The airplane went straight ahead into the trees before coming to a stop.
