JUST AFTER A LINEMAN RELEASED THE HELICOPTER TOW LINE FROM A POWER LINE THAT WAS BEING POSITIONED ON A POWER POLE, THE HELICOPTER TOW LINE BLEW BACK INTO THE POWER POLE GUY WIRES. INSTEAD OF RELEASING THE TOW LINE AT THAT TIME, THE PILOT ATTEMPTED TO MANEUVER THE TOW LINE AWAY FROM THE GUY WIRES. DURING THIS PROCESS THE PILOT LOST SIGHT OF THE TOW LINE, AND THE TOW LINE ENGAGED ONE OF THE GUY WIRES.
