NTSB Factual Report

During a night landing, the pilot misidentified the runway surface, and landed the airplane in a snowbank on the left side of the runway. He stated that most of the runway lights had been covered by heavy snow, and were not clearly visible on the straight-in approach. The airplane sustained substantial damage to both wings, and the horizontal stabilizer.

NTSB Probable Cause

The pilot's improper identification of the runway surface. Contributing to the accident was the snow covering the runway lights.
