The pilot departed on a positioning flight to pick up a medical crew. As he neared the helipad, he performed a right 180° circling approach. After completing the turn, the pilot thought he was a little low on final approach, and "pulled in a little collective" as he leveled the helicopter, which contacted the landing pad "firmly." Before the subsequent departure, the pilot felt a vibration, and he shut down the helicopter to investigate. The crew walked toward the tail and noticed a slight bend in the lower vertical fin, the tips of both tail rotor blades missing, and the helipad safety fence missing a small section of the fence-edge pipe. Further examination of the helicopter identified cracks in the tail boom structure. A security camera video of the helipad showed that the helicopter's tail rotor impacted the fence during the landing.
Probable Cause: The pilot's failure to maintain clearance from fencing around the landing pad during landing, which resulted in the tail rotor contacting the fence.
