The pilot reported minor injuries. Visual meteorological conditions prevailed during the 14 CFR Part 137 aerial application flight. The airplane was not operating on a flight plan. The flight was originating at the time of the accident. In his written statement, the pilot stated that he had completed two previous flights earlier in the day. He said that on the accident flight he had about 15 gallons of fuel and 110 to 120 gallons of chemical spray on board. He stated that the airplane departed and lifted off at the same point as the two previous flights. He said that on climb out he made a shallow bank to the right. He said that the airplane was downwind of some grain elevators. The pilot said that the airplane had started to lose lift and altitude. He dumped the airplane's chemical load. After dumping the load, he said that he still would not have enough time to recover because of the grain elevators coming up in front of him and the oil company to the south. He said that there was a ditch in his flight path and that he decided to put the airplane down there without hurting anyone on the ground. The plane came to rest approximately 100 feet from its impact point. The pilot stated that the wings, landing gear, engine, hopper, and fuel tank were damaged in the "crash".
