Probable cause

The engine failed due to a cracked cylinder and the pilot was forced to attempt a landing in a rice field where the gear collapsed.

Analysis

The pilot stated that shortly after takeoff the engine quit. The pilot attempted to dump the load he had onboard and attempted an emergency landing in a rice field. During the forced landing the main gear collapsed and the hopper and both wings were damaged. Examination of the engine revealed that the number 9 cylinder had cracked.
