NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot said the purpose of the flight was to practice takeoffs and landings in the snow. The landing gear was a tailwheel configuration equipped with skis. During the takeoff, the airplane lifted off prematurely after crossing a small berm. The airplane descended back down onto the snow, the left ski submerged under the surface, the left wing tip and the propeller struck the snow, and the airplane nosed over and came to rest inverted. The pilot reported 130 hours of total flight experience, of which, 30 hours were in make and model and 12 hours were on skis. The pilot said he had no formal instruction in ski-equipped airplanes, and that there were no mechanical deficiencies with the airplane.

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

The pilot's improper touchdown in the snow after the airplane became prematurely airborne during an attempted takeoff. A factor was the pilot's inadequate training.
