NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
Prior to the night landing, the pilot verified with an airport employee, that the runway lights were operational. During the landing flare to runway 26 the pilot lost visual contact with the runway due to the snow banks obscuring the runway lights. The airplane landed and veered off of the runway into the snow bank, resulting in substantial damage. The pilot reported no anomalies with the airplane or its systems. According to several witnesses, the pilot reported to them that his landing lights were not functional at the time of the landing. Several Notices to Airmen (NOTAMs) had been issued prior to the accident. These addressed 4 foot snow banks on runway 8/26, 7 foot snow banks on runway 18/36 and no braking action on runway 18/36. After the accident the airport manager issued a NOTAM about obscured runway lights.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot's inability to maintain directional control resulting in an impact with a snow bank. Contributing factors include the obscured runway lights, inoperative landing lights, and the pilot's improper decision to operate an airplane with known systems deficiencies. Full narrative available
