NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this public aircraft accident report.

The private certificated pilot, a Fish and Wildlife Protection Officer, and the passenger, a State Trooper, were utilizing a wheel/ski-equipped airplane to conduct surveillance activities of hunters. The pilot was landing to the west on the hard packed snow and ice-covered lake, which he thought would required a correction for a left crosswind. After landing, as the airplane neared the end of its 950 long landing roll, the nose of the airplane veered to the left, and the airplane began to slide sideways. The airplane turned about 90 degrees to the left, and the right ski dug into the snow. The right wing and right stabilizer subsequently struck the surface of the frozen lake. The pilot noted in his written report: "As I exited the pilot's side of the aircraft, I was extremely surprised to find that the wind was actually a left quartering tailwind, at about 15 knots." The airplane sustained substantial damage to the right wing and right stabilizer. There were no preaccident mechanical anomalies noted with the airplane.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's inadequate evaluation of weather conditions, which resulted in an on ground encounter with terrain during the landing roll. Factors associated with the accident were a tailwind, and snow-covered, icy terrain conditions.
