Accident Summary
Approximately three miles from landing, the pilot was completing the before-landing checklist when the engine surged to 2,700 rpm two or three times and then stopped developing power entirely. The pilot determined that a forced landing to a corn field was the best option. The landing was accomplished, but the airframe sustained substantial damage.
Post-Crash Examination
FAA inspectors examined the aircraft after the accident. They found that adequate fuel was onboard. Inspection of the engine, fuel, ignition, and airframe components revealed that the fuel selector cover assembly was loose, missing mounting screws, and had shifted aft of its designed position. According to the inspectors, such a repositioning would render the mechanical safety stop that prevents inadvertent selection of the "off" position inoperative.
Maintenance History
A search of the aircraft maintenance logs showed an entry indicating that the seats, door panels, plastic, and carpeting had been removed for replacement or cleaning. No other relevant maintenance entries were noted.
Probable Cause
The investigation report did not state a probable cause for the accident.
