Analysis

The purpose of the flight was to break in the newly overhauled engine. The pilot stated that he had been flying around the local area for about 25 minutes when he heard a clank and the engine lost complete power. The pilot determined that a tree landing was impending due to the lack of an open field. The acft collided with trees in a nose high, wings level,stalled attitude. The acft came to rest in a tree about 10 ft AGL. Disassembly of the engine disclosed the crankshaft gear had failed. Metallurgical exam determined high cycle fatigue.
