While seeding a rice field on the sixth flight of the day, the engine began to lose power. The pilot made an emergency landing in an adjacent rice field that was flooded and muddy. On the landing rollout the main landing gear wheels dug into the mud and the airplane nosed over. Examination of the engine revealed that the number 3 cylinder exhaust valve area had a crack that extended from the rocker shaft to the push rod boss area. No further anomalies were observed with the engine.
Probable Cause: The broken exhaust valve rocker arm of the number 3 cylinder that resulted in a total loss of engine power during an aerial application flight.
