Analysis

The aircraft collided with a snowbank 10 feet beyond the threshold during landing. After the accident the pilot reportedthat during the final approach to a landing on runway 32, the left main landing gear contacted a 2 foot high snowbank just beyond the threshold lights. The scissors assembly of the left main gear was broken and allowed the wheel to ROTATE360 degrees on the axis of the strut. Directional control was maintained and the acft remained on the runway. At first damage was thought to be minimal. After further inspection for repairs to the structure the damage was found to be substantial.
