Incident
A pilot lost control of an airplane during takeoff from Ann Arbor in poor weather conditions characterized by snowfall and low ceiling. The aircraft stalled and subsequently crashed into a field. All five occupants were evacuated from the aircraft, which sustained damage beyond repair. The airplane was not deiced prior to departure.
Investigation
Investigators reported several factors associated with the accident. The aircraft was observed to have encrusted snow approximately 1/8 to 1/4 inch thick on the top of the wing and tail surfaces. Additionally, airframe ice and the prevailing low ceiling and snow conditions were noted.
Probable Cause
The official probable cause is stated as inadequate preflight preparation on the part of the pilot, who failed to maintain flying speed after takeoff. Contributing factors include airframe ice, low ceiling and snow, and encrusted snow on the wing and tail surfaces.
