As the pilot was overflying the Rangers Cottage, he noticed two rangers run out, waving frantically. Believing they required assistance he landed the helicopter in the nearby car park. The rangers approached the helicopter and urged the pilot to move the helicopter as they were about to commence blasting. In his haste to clear the area the pilot overpitched the rotor blades. He attempted to land the helicopter on an access road but the main rotor blade struck a tall shrub, the aircraft yawed to the left and the tail rotor collided with the base of the bush before the helicopter landed. This accident was not the subject of an on-site investigation.
