Narrative:Immediately after takeoff the pilot sensed a loss of engine performance and attempted to return to the departure airstrip. Unable to maintain altitude, he dumped the chemical load and then initiated a forced landing to an agricultural (sugar beet) field. The pilot was unable to stop the aircraft before reaching an irrigation ditch and impacted the upsloping terrain at the ditch's opposite side. Partial disassembly of the engine revealed that a gear tooth from the engine's supercharger blower section had broken off and was found in the blower drive section.
Probable Cause: Loss of engine power due to failure of the supercharger impeller. A contributing factor was the ditch.
