Incident Details
The pilot reported that he was landing the aircraft in a clearing on telephone company right-of-way property in order to communicate with the company's ground personnel. At an altitude of about 100 feet, after turning his craft into the wind and maneuvering to avoid some loose ground wires, he descended for a landing. At about 10 feet above the ground, he heard a loud bang, and the aircraft shuddered violently, but he did not lose pedal control. He executed a hover auto rotation, landed the aircraft, and shut down the engine. After exiting the aircraft, the pilot discovered that the tail rotor and fins had struck a 2-inch metal fence post that was 7 feet tall.
