NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
According to the pilot he intended to overfly a local music festival. Both wing struts on the airplane were equipped with a flag measuring 3 feet by 2 feet. During the takeoff, it "appeared as if the engine was not making full power, possibly due to plug fouling." The pilot elected to abort the takeoff, and the airplane "overran the end of the runway, hit a barb wire fence, and flipped over into a stream on the other side of the fence" resulting in substantial damage. An examination of the engine revealed six fouled spark plugs and low compression on 4 cylinders. Density altitude was calculated to be 8580 feet.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the loss of engine power due to low cylinder compression and fouled spark plugs. Contributing to the accident was the pilot's inadequate preflight planning and preparation. Full narrative available
