Accident Details
The pilot reported that during a base-to-final turn, the aircraft was blown slightly off the runway centerline. A windshear effect from a nearby bluff was encountered. As the aircraft drifted to the right, it developed a high sink rate. The pilot added power in response.
Sequence of Events
The right main landing gear struck a snowbank at the edge of the runway. The aircraft continued in a relatively straight line for approximately 75 to 80 feet before nosing over.
Probable Cause
The official probable cause was an in-flight collision with terrain during landing flare/touchdown due to improper compensation for wind conditions by the pilot. Contributing findings included unfavorable wind, windshear, and a snowbank.
