The pilot reported that during a high speed fly-by to demonstrate the helicopter to prospective investors, he became distracted by a low engine coolant temperature. The pilot stated that he did not follow his intended flight path and did not see the power lines until the last moment. The pilot rolled the helicopter to a near 90 degree angle and the main rotor blades collided with and cut the transmission wires. The helicopter subsequently crashed in snow on level terrain.
Probable Cause: the pilot's failure to maintain clearance from power lines. The pilot's diverted attention and transmission wires were factors.
