Aircraft Accident/Incident Report

La Belle, Florida 33935
Monday, June 24, 2002 9:00 EDT

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

The pilot's failure to maintain visual lookout while maneuvering during an aerial application, which resulted in an in-flight collision with power lines and uncontrolled descent into terrain.
