On 25 October 2012, at about 1510 Eastern Daylight-saving Time a Helicopters Guimbal Cabri G2 (Cabri G2) helicopter, registered VH-CDU (CDU), departed Bankstown Airport New South Wales on a local training flight. On board the helicopter were an instructor and student. The instructor proceeded to demonstrate the recovery from low main rotor RPM in the hover. During the demonstration the helicopter began to rotate to the left. The instructor opposed the rotation with full right pedal however the rotation could not be stopped and the helicopter was landed heavily. There was minor damage to the helicopter as a result of the incident and the instructor and student were able to exit the helicopter without injury. 

As a result of this incident the helicopter manufacturer is preparing a service letter with the intention of preventing training sequences being performed that are inappropriate for the helicopter type.
