What happened
The accident occurred while an agricultural airplane was conducting a crop dusting mission. The pilot reported that the aircraft operated without any mechanical issues prior to the incident. During a left turn intended for a "clean-up" pass, the left spray boom made contact with the crops below. This contact caused the airplane to lose altitude and descend into the terrain, resulting in substantial damage to the airframe.
The investigation
The investigation focused on the mechanical condition of the aircraft and the sequence of events leading to the impact. The pilot stated that there were no known mechanical problems with the airplane prior to the accident. The physical evidence confirmed that the left spray boom contacted the crop, which led to the loss of control and subsequent descent into the wheat field.
Findings
The primary factor in this accident was the contact between the aircraft's spray equipment and the ground vegetation. The pilot was executing a low-altitude maneuver when the boom struck the crops. This interaction caused the airplane to descend into the terrain, resulting in substantial damage to the aircraft. No mechanical failures were identified as contributing factors.
Safety message
Pilots conducting agricultural operations should maintain heightened awareness of spray boom clearance relative to the terrain and crop height. Proper planning of turn radii and boom positioning is essential to prevent ground contact during low-altitude maneuvers.
