What happened
The accident occurred during an aerial application mission when the pilot was conducting a low-altitude maneuver over agricultural terrain. While making a left turn directly over high-voltage power lines, the aircraft collided with the cables. The impact caused the aircraft to crash and subsequently burn in a rice field located beneath the power line corridor.
The investigation
A post-accident examination of the wreckage revealed specific evidence consistent with contact with electrical conductors. Investigators identified two distinct wire marks and two electrical arc marks on the left wing of the aircraft. Additionally, wire marks were found on one of the propeller blades. These physical indicators confirmed that the aircraft had struck live power lines prior to impacting the ground.
Findings
The examination of the airframe and propulsion system showed no evidence of pre-impact failure or malfunction that would have contributed to the accident. The collision was determined to be the result of the aircraft's proximity to the high-voltage infrastructure during the turn. No preimpact failure or malfunction was evident in the mechanical systems of the aircraft.
Safety message
Pilots conducting aerial application operations must maintain strict awareness of terrain and overhead obstacles, particularly high-voltage power lines which may not be easily visible at low altitudes or during rapid maneuvers.
