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

The airplane was being operated by the private pilot as a visual flight rules (VFR) personal cross-country flight under Title 14, CFR Part 91. The pilot said he landed the ski-equipped airplane in a snow-covered meadow. He said the snow conditions were not what he had expected, and prior to takeoff, he had to dig the airplane out, and pack down an area around the airplane with his snowshoes. He said he packed down a takeoff area, and removed as much gear from the airplane as possible to lighten the takeoff load. During the takeoff roll, the pilot said the airplane veered off the packed area, burying the right ski and wing in the snow. The mechanic who examined the airplane said both the fore and aft main spars in the right wing would have to be replaced. The airplane was not examined by the NTSB.

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

The pilot's selection of unsuitable terrain for takeoff, which resulted in a loss of directional control on the ground, and the wing impacting the snow-covered terrain. A factor associated with the accident was the snow-covered terrain.
