A pilot conducting a smoke dispensing run along the north edge of a field collided with a powerline immediately after completing a left turnaround, resulting in a crash.

What happened

The pilot was engaged in an agricultural operation involving smoke dispensing along the northern boundary of a designated field. The flight path followed a west-to-east trajectory parallel to the north edge of the target area. A powerline ran along this same northern edge, creating a potential hazard at low altitude.

Upon completing the linear smoke run, the pilot initiated a left turnaround to reposition for the next pass. During the execution of this maneuver, the aircraft struck the overhead powerline. The impact caused the aircraft to crash immediately following the collision.

Probable cause

The pilot's failure to maintain adequate clearance from an obstruction (powerline) during a low-altitude turnaround maneuver while conducting smoke dispensing operations.
