Aircraft damage: Substantial
Location:Danville, KY -   United States of America
Phase: Unknown
Departure airport:Danville, KY (DVK)
Destination airport:
Investigating agency: NTSB
Shortly after takeoff, a steady stream of dark gray smoke was seen emanating from the homebuilt gyrocopter. The gyrocopter then turned left, climbed, and appeared to be returning to the airport. However, it impacted a field about 1 mile south of the airport. An FAA inspector examined the engine. When he attempted to rotate the crankshaft by hand, a metal binding was heard. Further examination of the engine revealed that a connecting rod bearing had seized in the number one cylinder. The non-certificated engine had been removed from an automobile, and installed on the gyrocopter by the pilot.
Probable Cause: Failure of a connecting rod bearing, which resulted in a loss of engine power during climb.
