N30227

The pilot reported that the airplane experienced a total loss of engine power while in cruise flight. He attempted to restart the engine without success and executed a forced landing to a field. Upon landing in the snow-covered field, the airplane nosed over and came to rest on its back. The airplane sustained substantial damage, including damage to both wings and the horizontal stabilizer. In his written statement, the pilot said that he decided not to add additional fuel prior to the flight because his fuel calculations showed that he should have had at least 30 minutes of fuel reserve upon arrival at the destination airport; however, he did not use a calibrated instrument in determining the preflight fuel quantity. He further stated that the accident could have been prevented by adding additional fuel prior to the flight. He listed no mechanical malfunctions of the airplane on his written report.
