Analysis
The pilot reported that he had completed an agricultural spray operation and was returning to land. He stated that the airplane got too low on the approach and descended into the soybean crop off the approach end of the runway. The airplane impacted the end of the airstrip and the landing gear collapsed. He stated that everything on the airplane was operating normally and that the accident resulted from pilot error by coming in too low and allowing the airplane to contact the soybean crop. The airplane sustained substantial damage to the fuselage near the landing gear mounting area.
