The NTSB's narrative final · quoted from the NTSB record

According to the instructor, they were practicing ground maneuvers at approximately 6,000 feet msl when the engine began to "run rough." The instructor said they were unable to maintain altitude, and while returning to the airport the "engine quit." The instructor made a forced landing in a snow-covered field. During the landing, the airplane's nose landing gear caught the snow and the airplane nosed over. The airplane's nose landing gear was displaced aft, buckling the firewall. The empennage was buckled just aft of the rear window, and the vertical stabilizer was crushed. The instructor said the field was covered with over a foot of snow. An examination of the airplane's engine revealed a hole in the number 1 piston, and a fractured exhaust valve for the number 1 cylinder.
