Incident Overview
A pilot landed an airplane on a snow-covered runway, resulting in the aircraft nosing over and coming to rest inverted. The pilot reported that upon arrival at the airport, he observed that the runway had not been recently plowed of snow. He performed a low pass to the north over the runway in an attempt to determine the snow depth. After turning the airplane around, he approached the runway to the south to conduct a run and "drag" the wheels on the snow.
Sequence of Events
The wheels contacted the snow just past midfield. The pilot stated, "Immediately we were in too deep and I was unable to pull it out or add power..." The airplane then nosed over and came to rest inverted.
Airport Status
Airport personnel reported that the airport was NOTAMed closed since December 27, 1992. The pilot did not make contact with the airport operator prior to the accident and stated that he was unaware that the airport was closed.
