What happened
The aircraft was engaged in agricultural operations, specifically performing crop dusting duties. After completing a reload of its chemical payload, the pilot commenced the first swath run over a corn field. During this initial pass, the aircraft failed to achieve and maintain level flight as intended. Instead of leveling off at the appropriate altitude, the aircraft continued to descend until it made contact with the crops below.
The impact with the vegetation created significant additional aerodynamic drag on the airframe. This sudden increase in resistance caused the aircraft to lose airspeed rapidly and enter a stall condition. The stalled aircraft then impacted the ground directly. Following the accident, the pilot stated that the aircraft had been misloaded prior to the flight. He attributed the uncontrolled descent to this overload condition. Despite recognizing the situation, the pilot did not initiate the jettison of the load during the encounter.
The investigation
The investigation focused on the mechanical and operational aspects of the accident sequence. Examination of the event revealed that the primary issue was the failure to maintain altitude during the agricultural run. The physical evidence supported the narrative that the aircraft struck the crop field rather than a hard surface initially.
Findings
Several critical factors contributed to the accident. The aircraft was determined to be overloaded due to misloading of the chemical payload. This excess weight compromised the aircraft's ability to maintain level flight during the low-altitude operation. Furthermore, the resulting stall was a direct consequence of the drag generated by contact with the corn crops. The pilot's decision not to jettison the load during the critical phase of flight prevented any potential recovery from the developing stall condition.
