Analysis

The plt reported that he was spraying the end rows of a field when the helicopter approached some wires. He stated that he saw the wires at the last second & tried to get under them. Reportedly, the helicopter crossed below a set of power lines, but struck a telephone line. The plt initiated a landing; however, the wire became 'fouled in the controls' making control difficult. The plt reported that the helicopter touched down a little too fast, bounced twice & rolled over.
