On July 2, 1994, at 2237 central daylight time, a Cessna 150, N63277, registered to Maynard Stensrud and piloted by a private pilot, nosed over during a forced landing following a loss of engine power. The forced landing was made in a field 1 1/2 miles from the destination airport in Waseca, Minnesota. The airplane was substantially damaged. The pilot and passenger were not injured. The flight originated from Brookings, South Dakota, on July 2, 1994, at 2030 cdt. The pilot stated that when nearing the destination airport, the engine began to run rough. He initially planned to land on a county road; however, upon determining he was unable to do so he landed the airplane in a corn field. According to the Waseca County Sheriff's report the airplane touched down just south of the road, contacted a ditch, became airborne, then travelled into a corn field where it came to rest inverted. An inspection of the airplane by the airplane owner, and witnessed by a Sheriff's Deputy, revealed 45 ounces of fuel remained throughout the fuel system of the airplane. The pilot departed Waseca, Minnesota, earlier on the day of the accident, flew to Brookings, South Dakota, and was returning to Waseca when the accident occurred. The airplane had full tanks upon departed Waseca and was not refueled during the trip. The pilot stated to a Federal Aviaiton Administration Inspector that he failed to perform a complete preflight regarding fuel calculations prior to departing Brookings. The pilot reported on NTSB Form 6120.1/2 that better preflight planning could have preventing this accident.
