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 pilot stated he conducted an engine run up and the airplane experienced a magneto drop. A subsequent check of the magnetos revealed no anomalies. The pilot departed from runway 24 and the airplane was about 50- feet above the ground when the engine experienced a partial loss of engine power and a reduction in engine rpm. The pilot initiated a forced landing and the airplane collided with power lines and the ground. Examination of the engine assembly and fuel system revealed no anomalies. The left and right magnetos were removed. The right magneto was turned by hand and spark was present on all ignition towers. The left magneto would not produce an ignition spark when turned by hand. The left magneto was disassembled. The coil was removed and internal oil from the coil was present on the rotor and housing.

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

The total failure of the left magneto resulting in a partial loss of engine power on initial takeoff climb, forced landing, and in-flight collision with wires and the ground.
