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

During cruise flight, the engine lost power and the airplane impacted the terrain short of the alternate airport. The 123-hour private pilot stated the engine "suddenly stopped producing power." He attempted to restart the engine; however, he was not successful. During the forced landing, "strong surface winds came up," and the airplane impacted the terrain approximately 450 feet short of the runway. The airplane then struck trees, a fence, two poles and came to rest on the runway surface. Examination of the engine revealed the crankshaft bolt and crankshaft dowel pin had fractured and failed. The bolt fracture surfaces displayed signatures consistent with fatigue. At the time of the accident, the engine had accumulated approximately 576 hours since major overhaul.
