NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The airplane experienced a partial power loss after takeoff, then crashed less than one mile southeast of the airport. A subsequent examination of the engine showed one magneto with a non-standard repair to a mounting lug; evidence of oil seepage in both magnetos; several spark plug electrodes excessively worn; a ruptured seal and oil seepage in the engine driven fuel pump; and corrosion, contaminants, and evidence of previous water contamination in several areas in the fuel system. Any of these discrepancies could have impacted the production of engine power.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A partial loss of engine power due to the substandard and incomplete maintenance of the engine.
