What happened
Prior to the accident, the aircraft was moved from an unheated hangar during moderate snowfall. Approximately 15 minutes before departure, the pilot taxied the plane to the runway. At this time, snow was visibly present on the wings, the horizontal stabilizer, and the ground. While the aircraft featured deice boots, these are designed for use during flight rather than for clearing surfaces prior to takeoff.
As the aircraft began its departure, witnesses observed the plane flying at a low altitude with a loud engine. Shortly after rotation, the left wing dropped, and the aircraft entered a left-wing-low attitude. The plane subsequently struck a line of trees and impacted the ground. The impact and a subsequent fire resulted in the total destruction of the aircraft. Evidence from the engine and propeller indicated that the engine was producing power and the propeller was rotating at the moment of the crash.
Findings
Investigation of the wreckage showed no mechanical failures or pre-impact anomalies that would have prevented normal flight. The departure airport lacked de-icing or anti-icing services. The primary cause of the accident was snow accumulation on the aircraft surfaces, which led to an aerodynamic stall. The presence of snow on the wings and stabilizer increased drag and significantly reduced lift, causing the aircraft to lose control during the initial climb.
