Probable cause

The pilot's inadequate removal of frost from the wings, and his failure to attain adequate airspeed during takeoff initial climb, which resulted in a stall and collision with terrain. Factors contributing to the accident were the pilot's delayed aborted takeoff, and an inadvertent stall.

Analysis

The private certificated pilot was departing uphill from a 1,950 feet long runway on a Title 14, CFR Part 91 local area personal flight. The pilot indicated that prior to departure, the upper wing surfaces of the airplane had a layer of frost, but he smoothed the surface with a broom. During the takeoff roll, the pilot said the airplane became airborne in ground effect to an altitude of about 2 feet, about 300 feet before the end of the runway. The airplane stalled and collided with alder bushes about 75 feet beyond the end of the runway. The airplane received damage to the wings, fuselage, and engine.
