Read the full NTSB narrative

The pilot reported a partial loss of engine power during departure from a rural village. He said the airplane was approximately 600 feet agl when he heard a loud 'clunk-clunk' and felt an engine vibration. He reduced power, and turned downwind to land on the same runway he had just departed. On the turn from base to final, he said the engine continued to lose power, and he was unable to maintain sufficient altitude to reach the runway. He made a forced landing in deep snow. Postaccident inspection disclosed a fractured connecting rod bolt. Metallurgical examination at the NTSB laboratory revealed a fatigue failure of the rod bolt. The engine was rebuilt approximately 1,642 service hours prior to the accident. The engine manufacturer recommends an engine overhaul at 2000 hours.
