What happened
Upon arriving at the airport, the pilot observed that the runway had not been recently cleared of snow. In an effort to assess the depth of the accumulation, the pilot performed a low pass over the runway from the north. Following this assessment, the pilot turned the aircraft around and approached the runway from the south, intending to use a running landing technique to "drag" the wheels through the snow.
The aircraft's wheels made contact with the snow just past the midfield point of the runway. The pilot reported that the aircraft immediately became stuck in the deep snow and was unable to recover or apply additional power. Consequently, the aircraft nosed over and came to rest in an inverted position. The pilot was not injured.
Airport personnel indicated that the airport had been closed via a Notice to Airmen (NOTAM) since December 27, 1992. The pilot did not contact the airport operator before the accident and stated he was unaware that the facility was officially closed.
