A pilot elected to land on Runway 21 to avoid a frost heave, resulting in a long landing on an icy surface that caused the aircraft to overrun into a snowbank and ditch.

What happened

The pilot reported that upon arriving at the airport, the wind had shifted to the northeast. Despite this change in conditions, he elected to land on Runway 21 specifically to avoid a frost heave located on the runway surface. To bypass the hazard, the pilot landed long. However, the runway was icy, and he was unable to stop the aircraft within the available distance.

The aircraft continued off the departure end of the runway and ran into a snowbank and ditch. In retrospect, the pilot believed that he should have executed a go-around and landed into the wind instead of attempting the landing on the contaminated surface.

Probable cause

The pilot's decision to land on a contaminated runway to avoid a frost heave, which resulted in an overrun.
