What happened
The incident occurred during an aerial application operation, specifically while the aircraft was conducting a swath run over agricultural fields. During this phase of the flight, the pilot struck a small electrical wire suspended above the ground. Following the initial contact, the pilot initiated a climb to evaluate the extent of any damage sustained by the airframe or systems.
After assessing the situation, the pilot descended and returned toward the field area. While maneuvering in close proximity to the power infrastructure, the aircraft nearly struck additional wires. Witnesses, including the property owner, described the subsequent flight path as an abrupt maneuver intended to avoid further contact with the power lines. During this evasive action, control of the airplane was lost. The aircraft subsequently impacted the terrain at a high rate.
The investigation
Investigative efforts focused on the sequence of events leading to the loss of control and the final impact site. Examination of the wreckage and witness statements confirmed that the initial contact with the electrical wire occurred during the agricultural operation. The property owner and other witnesses provided consistent accounts of the pilot's actions, noting the climb for inspection and the subsequent return to the field. Their testimony highlighted the sudden nature of the maneuver executed to avoid the power lines, which coincided with the loss of aircraft control.
Findings
The primary factors contributing to this accident were the initial strike on the electrical wire and the pilot's decision-making process following that event. The need to evaluate damage prompted a climb in an area with overhead obstructions. The return to the field brought the aircraft back into proximity with the power lines. The abrupt maneuver executed to avoid striking additional wires exceeded the aircraft's controllability or the pilot's ability to maintain safe flight parameters, leading directly to the impact with terrain.
Safety message
Pilots conducting low-level agricultural operations must remain vigilant regarding overhead obstructions such as power lines and communication towers. Striking any wire can cause immediate damage or distraction. If damage is suspected, pilots should assess the situation carefully before attempting to return to populated areas or infrastructure. Evading obstacles requires ample altitude and space; abrupt maneuvers at low altitude significantly increase the risk of loss of control.
