Piper PA-22-108
The airplane encountered snow on the runway during landing on a private airstrip and subsequently nosed over. The day prior to the accident the pilot reported that he removed snow from the runway. The pilot stated, "After setting down the left wheel got into the snow on runway edge. Braking and correcting the aircraft caught in the right edge of snow on runway. This pulled the nose wheel into the snow also. At this time the aircraft was slowing down fast. All of a sudden the left wing and nose came over and that was 'all over'."
