The pilot was operating into a modified platform located in mountainous terrain and built on a steep slope. He held the helicopter skids lightly on the platform, parallel to the heavy loose planks making up the platform, and side on to the slope. It was estimated that the tips of the main rotor blades were about 1.5 metres vertically clear of the slope, with the cyclic control in the neutral position and the rotors at normal operating rpm. A man was present in the rear cabin to receive trays of core samples from four others who carried the trays to the helicopter when a gust of wind suddenly caused the helicopter's tail to swing towards the slope. The left side of the helicopter then began to lift, resulting in the rotor blades striking small stumps and the ground forward of the stumps. The rotor strikes caused the main rotor and gearbox assembly to fling from the aircraft 10 metres down the slope and the engine compartment briefly caught fire. One crew member received minor injuries, and three of the ground personnel were also injured, one of them seriously.
