Helicopter was hovering approximately 40 feet AGL to assess the landing area. The helicopter moved laterally to the right in order to increase the visibility of the landing area. During this time, the helicopter rotated to the right and started to spin about the vertical axis. An attempt to control the rotational spin was made, however, there was little to no tail rotor effectiveness. CGNET was put down after the second rotation while striking the tail rotor on the ground and damaging the landing skids. There were no injuries
