Ground strike involving a Hughes Helicopters 269C, VH-ADL, 120km NNE Kalgoorlie/Boulder, Aerodrome, WA on 25 March 1996

It was reported that the pilot was hovering the helicopter in a 12-15 kt headwind, 10-15 ft above trees. Consequently, a less than average power setting was required to maintain height. The wind strength suddenly reduced and the helicopter descended towards the trees. The pilot increased collective pitch and power to stop the descent and re-establish the hover. Although the helicopter came close to the tree tops the pilot did not believe there had been any contact with them. Shortly afterwards, the pilot heard an unusual noise coming from the main rotor blades. He landed to investigate and found dents and holes in all three main rotor blades.
