Analysis

The pilot stated that he was spraying a rice field in formation with another airplane when his aircraft experienced an inflight upset due to the propwash, or wake turbulence, generated by the other aircraft. The landing gear struck a rice levee and was sheared off. The aircraft bounced from the levee and nosed over upon impact.
