The NTSB's narrative final · quoted from the NTSB record
According to the pilot, the engine lost power without warning as he retarded the throttle to 2,250 RPM, while leveling at 5,500 feet. The pilot attempted without success to restart the engine, and he elected to execute a forced landing to a road. Traffic conditions on the road prevented its use for a forced landing, so the pilot selected a field adjacent to the road that was covered with mesquite shrubs and clumps of bear grass. The pilot further stated that the selected field turned out to be rough and uneven. Postaccident examination of the engine revealed that the #1 exhaust valve head had separated from the valve stem, resulting in internal damage to the respective cylinder, piston, intake valve, and push rods.
