Aircraft Accident/Incident Report

Omaha, Nebraska 68144

NTSB Narrative Summary Released at Completion of Accident

The aircraft sustained substantial damage during a forced landing following a loss of engine power. The pilot reported the airplane experienced a propeller overspeed condition followed by a fluctuation in oil pressure. The pilot stated the engine started "banging" and lost power a few minutes later. The pilot performed a forced landing to a bean field, during which the main landing gear collapsed. Inspection of the engine revealed the number four engine cylinder connecting rod cap and cap bolts had fractured. A metallurgical examination revealed that the nut of one of the connecting rod cap bolts was partially engaged. The connecting rod cap showed evidence of fatigue cracking along the fracture surface. Fracture features of both connecting rod cap bolts indicated the bolts had separated due to overload.

NTSB Probable Cause Narrative

A loss of engine power due to a loose connecting rod cap bolt and the resulting fatigue failure of the connecting rod cap. A related factor was the unsuitable terrain.
