Incident Summary
A pilot reported that after flying for approximately four hours, the engine suddenly quit without any prior indication of trouble. The pilot executed a forced landing into a cornfield. The airplane was certified in the Experimental category and had undergone several modifications, including vortex generators, propeller tip modifications, gap seals, new stabilizer tips, electronic ignition, oversized pistons, a modified nose cowl, wheel pants, and add-on wingtip fuel tanks.
Post-Accident Findings
After the accident, the fuel system and electrical ignition system continuity were checked and no discrepancies were found. Before the airplane was removed from the cornfield, the pilot ran the engine. He reported that the engine started but ran rough. Upon inspection, he found that wires had been damaged during the accident; after properly reattaching them, the engine ran "beautifully." The pilot stated that he could not find anything mechanically wrong with the airplane.
