When the pilot attempted to increase power, the engine did not respond and shortly thereafter failed completely. The pilot jettisoned the spray load, turned, and executed a forced landing in a rice field. Upon touchdown, the aircraft encountered ruts and ground-looped. A post-crash fire ensued, destroying the aircraft.
