Probable cause

The pilot's failure to remove all the frost from the airplane and exceeding the gross weight limit of the airplane.

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

During the takeoff the airplane pitched up and the wings rocked from side to side and then the airplane settled and crashed into the snowbank and nosed over. The pilot stated there was frost on the wings but he brushed it off. Examination of the wing's upper surface revealed that frost remained on the upper surface. Examination of the cargo, airplane, and fuel information showed that the airplane weighed 3700 pounds. The certificated gross weight of the airplane was 3600 pounds.
