Aircraft stall and impact following takeoff in snowy conditions

No fatalities • Bellingham, United States of America • Takeoff (climb)

A pilot experienced a wing stall and subsequent ground impact during the initial climb phase due to snow accumulation on the aircraft surfaces.

What happened

During preflight operations, the pilot noted that snow was accumulating on the wings of the aircraft type while wiping the surfaces manually. As the aircraft taxied toward runway 16, heavy snowfall continued, leading to a light layer of wet snow settling on the wings. During the takeoff roll, the pilot observed snow shedding from the wings as the airspeed increased.

While climbing to an altitude of approximately 150 feet, the aircraft experienced a leftward yaw. The pilot attempted to correct the deviation using right aileron input but observed the onset of a stall. In an effort to recover, the pilot lowered the nose and reduced engine power to idle. The aircraft type subsequently struck a general aviation ramp in a left-wing-down orientation, sliding between 500 and 600 feet. The impact resulted in substantial damage to the fuselage and the left wing. There were no fatalities or injuries reported, and the pilot indicated there were no mechanical or engine malfunctions prior to the event.

Findings

Weather observations from the airport's automated station indicated that roughly 27 minutes prior to the accident, the area was experiencing moderate snow, freezing fog, and visibility of only 1/2 mile. The pilot's report suggested that inadequate deicing procedures contributed to the accident, noting that snow remained on the wings despite manual clearing efforts.

Probable cause

The aircraft experienced a stall during the climb due to the presence of snow on the lifting surfaces.
