Analysis

The pilot stated that he was landing in an open field on his property to attend a meeting. Upon arrival at the field, he performed an aerial survey of his intended landing site checking for wires or obstacles. He also evaluated the weather, which was clear with a calm wind. After landing, he noted that the group of people he was meeting with was on the other side of a ditch about 50 yards away, so he decided to hover-taxi closer to their location. As the helicopter traversed over the ditch, the pilot surveyed the area looking for wires and obstacles. Seeing none, he proceeded to make a turn to land. As the pilot initiated the turn, he saw power lines about 40 feet in front of and above the helicopter. He made a quick right turn to avoid the power lines, "but made contact with the tail rotor…." Not knowing the damage to the tail rotor, he lowered the collective and landed as quickly as possible from an altitude of about 8 feet. The pilot stated that in his urgency to shut down the helicopter, he "dropped the collective very fast," which he stated caused the main rotor blades to impact the tail boom. In the section titled "Recommendation (How could this accident/incident have been prevented?"), the pilot stated that he got out of his normal routine of performing a pre landing inspection of his intended landing area when he decided to hover-taxi to an alternate location. The pilot reported that there were no mechanical problems with the helicopter.
