NTSB Narrative Summary Released at Completion of Accident
The pilot purchased the airplane two days prior to the accident and was ferrying it back to his home airport. He serviced the airplane with 26 gallons of fuel at the first refueling stop, and shortly after takeoff, the engine experienced a partial loss of power. The pilot performed a forced landing when he was unable to regain sufficient engine power. Examination of the engine revealed the carburetor bowl and engine-driven fuel pump fuel screens were clean with no visible contaminants. The engine was not able to be run due to impact damage; however, thumb compression and valve train continuity was confirmed to all cylinders.
NTSB Probable Cause Narrative
The loss of partial engine power for undetermined reasons.
