Analysis

The helicopter was being used in the construction of elect transmission lines. A 150-FT longline cable had been utilizedon an earlier flight for lifting external loads. However, there was no reason for the longline to be attached on the accident flight as the pax were being transported in conjunction with their construction & inspection duties. The helicopter took off with the longline attached & no external load. After takeoff, the helicopter moved forward about 200 ft to a treeline & began a left turn, away from tower 51 where the takeoff was initiated, toward a point where one of the pax was to be discharged. As the helicopter flew over the trees the longline became entangled in the trees.
