Analysis

The purpose of the flight was to survey alligator nests along a canal. According to the pilot, they had been flying low (50 to 100 feet), at approximately 35 miles per hour, along the canal when the passenger warned him of utility lines crossing their intended route of flight. As the pilot executed a quick stop maneuver to avoid a collision with the utility lines, the tail rotor assembly collided with the ground. No mechanical problems were reported. The pilot also stated that a better scanning technique, and a slightly higher altitude may have prevented this accident.
