Background
The flight was conducted to survey alligator nests along a canal. According to the pilot, the aircraft was flying at an altitude between 50 and 100 feet, at approximately 35 miles per hour, following the canal.
Incident
During the flight, the passenger alerted the pilot to utility lines crossing the intended route. In response, the pilot performed a quick stop maneuver to avoid a collision with the lines. As the aircraft decelerated, the tail rotor assembly made contact with the ground. The pilot reported no mechanical problems with the aircraft.
Pilot's Comments
The pilot noted that improved scanning techniques and flying at a slightly higher altitude might have prevented the occurrence.
