Analysis

The pilot was executing swath runs to apply herbicide solutions to weed plants. While finishing with the second load of spray, the pilot maneuvered to turn the helicopter around and struck unmarked power lines approximately 75 to 100 feet above the ground. The pilot then lost control of the helicopter, and it came down on its side and impacted trees. The pilot reported no mechanical malfunction. Examination of the wreckage revealed the main rotor system was damaged, the tail boom was separated, the canopy was shattered, and one skid was separated.
