NTSB Narrative Summary Released at Completion of Accident

While the pilot was cruising between airstrips during an agricultural flight, the engine's power output fluctuated. Then, engine power was lost. The pilot attempted to make a forced landing in a nearby field. However, on approach the airplane impacted a dirt berm and nosed over in the soft field. Thereafter, it was destroyed by a ground fire. The event that precipitated the loss of engine power was not ascertained because of the fire damage to the airplane.
