Investigator assessment
Analysis narrative
The pilot stated he touched down with a small bounce, drifted to the right edge of the runway, and caught the right main tire in the deep snow. The airplane nosed over and came to rest inverted which resulted in substantial damage to the left wing and vertical stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The Cessna 150 had been converted to a tailwheel configuration.
