Hard landing involving a Amateur Built Aircraft CH-7, VH-NGL, Bankstown, Aerodrome, NSW on 27 May 1996

The student pilot reported that he was hover taxiing along a taxiway, in a slight tailwind. As he passed through an S bend, the helicopter began to yaw to the left. He rapidly applied right pedal to counter the yaw, but overcorrected. The helicopter then began to rotate to the right, causing the pilot to believe the aircraft had suffered a loss of tail rotor effectiveness. The pilot wound off the throttle, to reduce the torque effect of the main rotor, however the helicopter landed heavily, damaging the skids. The pilot had minimal experience on this type of helicopter, having gained the majority of his flying experience on R22 helicopters.
