The airplane was substantially damaged when it impacted trees and terrain during a forced landing at night following a mechanical failure of the engine. Examination of the engine revealed that one of the engine cylinders had failed due to fatigue. The origin of the fatigue region coincided with an area that had been thinned by corrosion. The area in question had been covered by gray paint. Checks performed at the most recent annual inspection revealed normal compression readings on all cylinders.
Probable Cause: The fatigue failure of the engine cylinder which resulted in a complete loss of engine power, and the unsuitable terrain encountered by the pilot during the subsequent forced landing. Contributing to the accident were the night lighting condition, and trees.
