The pilot stated that on 12 March 2010 at approximately 1030Z he took off from Glenside Private Aerodrome in the Winterton area, accompanied by three passengers, on a scenic flight. During the flight, he requested one of his passengers to take some aerial photos of his farm while he was orbiting overhead the farmstead.

The pilot then raised the collective pitch lever, which accelerated the yaw to an extent which the pilot could not control. During the yaw to the right, the helicopter collided with a tree, breaking off a part of the tail boom and striking the ground. One of the passengers sustained a laceration to his forehead and left eye while the pilot and the other two passengers did not sustain any injuries. The aircraft was destroyed during the sequence of the accident.

Contributing factor Lack of training ' improper training in loss of tail rotor effectiveness. Low experience level of the pilot on the helicopter type.
