Narrative:Shortly after takeoff, the pilot of an agricultural airplane experienced a total loss of engine power. Unable to restore engine power, the pilot made an emergency landing in a cornfield, which resulted in substantial damage to the airplane.
The engine was removed from the airframe and an engine examination revealed small bits of metal in the oil filter element and that the engine was seized. The top cylinder was removed, the cylinder's connecting rod was broken, and metal fragments were noted inside the engine. A bottom cylinder was then removed, and a broken section of the master connecting rod was retrieved. Metallurgical examination determined that the connecting rod separated due to overstress fracture, with no indication of pre-existing cracking.
Probable Cause: The total loss of engine power due to a failure of the master connecting rod.
