Narrative:
According to the pilot, he was performing touch-and-go landings on runway 03. During the landing roll, he experienced a tailwind, and the airplane departed the right side of the runway. The airplane's wheels sank into snow about 12 inches deep, and the airplane nosed over. The right wing strut was bent, and the top of the vertical stabilizer and the rudder were crushed. The following wind conditions were recorded by the Automated Surface Observing Station at the airport: At 0956, wind from 360 degrees at 3 knots. At 1056, wind from 190 degrees at 11 knots. At 1112, wind from 200 degrees at 14 knots, remark wind shift at 1052. The pilot reported that after the accident, he was told that "the wind had shifted to about a 10 knot tailwind from that reported by the FBO and [he] was unprepared for this condition."

Probable Cause: The pilot's failure to maintain directional control during the landing roll, which resulted in a loss of control and subsequent nose over. Contributing factors were the tailwind and the soft snow-covered terrain.
