Observation and Flight Path
The aircraft was observed at low altitude, descending on a northerly heading approximately 1.5 miles south of the crash site. Engine sounds were characterized as smooth and normal.
Collision with Transmission Line
The aircraft struck a 44,000-volt transmission line. The impact parted a 5/16-inch diameter hi-strength steel ground cable and a 1/0 aluminum/steel conductor. Subsequently, 18 turns of the steel cable were removed from around the propeller shaft. Approximately 1,820 feet of the steel cable was pulled from the support structures.
Aftermath
After striking the transmission line, the aircraft continued for about 457 feet and came to a stop. The aircraft then burned.
