Aircraft Accident/Incident Report

Chiloquin, Oregon 97624
Thursday, August 10, 2000 16:00 PDT

NTSB Narrative Summary Released at Completion of Accident

Shortly after takeoff, at an altitude of approximately 150 feet above ground level (AGL), the airplane developed a rough running engine and the pilot initiated a forced landing to a nearby highway. The pilot stated that he planned on landing the airplane on a non-congested area of the highway, however, the aircraft collided with a flatbed tractor-trailer combination that was traveling on the Interstate. Post-accident inspection and teardown of the airplane's engine revealed that the engine's crankshaft was fractured and had separated between the number three and number four crankpins.

NTSB Probable Cause Narrative

Loss of engine power due to a fracture and separation of the engine's crankshaft. A factor was a vehicle on the roadway.
