Probable cause

Pilot's not removing the frost from the airplane before attempting to takeoff. Contributing to the accident was the pilot's delayed abort, and the berm.

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 private pilot attempted to takeoff with frost on the upper surfaces. When he realized the airplane was not going to fly before reaching the end of the runway, he aborted the takeoff and steered it off the runway and into a snowberm. He said he thought the runway was about 2,000 feet long. FAA records show it to be 1,250 feet long.
