The engine lost power and while making a forced landing in a field the aircraft collided with a power pole and then crashed on top of a pile of railroad ties. Postcrash examination of the engine showed the no. 1 exhaust valve guide and valve stem were eroded, the valve guide had partially separated due to progressive cracking, and the valve head had separated from the stem. The reason for the valve stem and guide erosion was not determined. The engine had accumulated 2,225 flight hours since the last major overhaul, at which time the valves and valve guides were replaced with new parts. The recommended overhaul interval for the engine is 2,400 flight hours.
Probable Cause: Failure of the no. 1 cylinder exhaust valve guide due to erosion, which resulted in separation of the exhaust valve head, loss of engine power, and collision with a power pole during a forced landing on unsuitable terrain.
