Analysis

The helicopter plt turned at the end of a spray run & the acft collided with a power line. He said that because of a quartering tailwind, the helicopter was in a nose high attitude & the tail rotor hit a wire. The plt was able to make an autorotation after the helicopter spun a few turns, but it touched down hard enough to rupture fuel lines which resulted in a fire.
