On 29 September 2011, a Robinson Helicopter, R22 Beta II helicopter (R22), registered VH-RTB, was conducting aerial stock mustering operations about 43 km east-south-east of Maningrida, Northern Territory.
While guiding a herd of buffalo into the yarding area, at about 20 ft above ground level, the helicopter's tail rotor struck a tree. The helicopter landed heavily and sustained serious damage.
This accident not only highlights the challenging nature of
aerial stock mustering operations, but also the benefits of
utilising resources such as a ground support teams, when operating
within the yarding area.
