The pilot of the accident helicopter reported that he was attempting to takeoff from a glacier. During takeoff, he discovered the right landing gear skid was frozen to the surface of the glacier, and he decreased the collective control input. As he reduced the collective control input, the right skid broke free from the ice. He said that due to left cyclic input, when the right skid broke free from the ice, a left rolling moment was induced. The helicopter's main rotor blades subsequently contacted the surface of the glacier, and the helicopter rolled onto its right side.
Probable Cause: The pilot's failure to maintain aircraft control during takeoff, which resulted in dynamic rollover of the helicopter. A contributing factor was the frozen terrain.
