Incident Overview
According to the pilot, the flight was intended to overfly a local music festival. Both wing struts of the airplane were equipped with flags measuring 3 feet by 2 feet. During the takeoff roll, the pilot reported that it "appeared as if the engine was not making full power, possibly due to plug fouling." In response, the pilot elected to abort the takeoff.
Accident Sequence
The airplane subsequently overran the end of the runway, struck a barbed wire fence, and flipped over into a stream on the other side of the fence. The accident resulted in substantial damage to the aircraft.
Engine Examination
An examination of the engine following the incident revealed six fouled spark plugs and low compression on four cylinders. The density altitude at the time was calculated to be 8,580 feet.
Remarks
The pilot's account and the engine findings suggest potential power loss, but the source does not explicitly state a causal relationship between the engine condition and the aborted takeoff or subsequent overrun.
