Aircraft Accident/Incident Report

Collins, Ohio 44826
Monday, July 26, 1999 8:30 EDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was in cruise flight approximately 2,000 feet mean sea level. The engine lost all power, and the pilot made a forced landing to a soybean field. The pilot stated that examination of the wreckage revealed four bolts, which secured the propeller, were sheared. The respective four nuts and propeller were not recovered. The pilot believed that one bolt sheared, and a subsequent vibration caused the remaining bolts to shear. On this particular airplane, the propeller acted as a flywheel. The absence of a flywheel would cause the engine to stop.

NTSB Probable Cause Narrative

In-flight separation of the propeller.
