Analysis

The pilot radioed that he had smoke in the cockpit. He immediately made an emergency landng, down wind, in a farmer's field. Witnesses saw the aircraft's right wing drop before the plane touched down. The resulting impact tore the wings and engine off, killing the pilot, but the passenger survived. An investigation revealed that a field wire in the generator had shorted. This allowed unregulated voltage through parts of the wiring harness and cause the insulation to overheat and smolder.
