Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during cruise flight the airplane suddenly started shaking violently. He reduced the engine power and noticed the vibration diminished. The pilot selected a field and attempted an off-airport landing, during which the airplane nosed over. The airplane sustained substantial damage to the wings and vertical tail. A postaccident examination of the airplane's engine revealed that the No. 5 piston was fragmented. The engine had last been overhauled 17 years prior to the accident, and had accumulated 740 hours since the overhaul.

Factual narrative

The pilot reported that during cruise flight the airplane suddenly started shaking violently. He reduced power and the shaking was not as bad. The pilot selected a field and attempted an off-airport landing. During the landing, the "nose wheel dug in" and the airplane nosed over. The airplane sustained damage to the propeller, nose landing gear, wings, and vertical tail. Examination of the airplane's engine revealed that the number 5 piston was fragmented. The engine had last been overhauled on April 23, 1993, and had accumulated 740 hours since that overhaul. The logbook entry for the piston showed that it was a Superior Air Parts piston, part number SA640518.
