NTSB Narrative Summary Released at Completion of Accident

The helicopter is configured with an external horizontal platform mounted adjacent to the left loading door, between the fuselage and the skids, for use during in-flight transfer of a lineman from aircraft to structure during inspections of high tension transmission line supports. The exact procedures for the in-flight lineman transfer call for the helicopter-to-structure static electricity grounding cable to be clamped to the structure prior to the actual transfer. By design, the ground cable clamping is the very first procedural task and the unclamping is the very last procedural task. When the pilot sees the cable and clamp returned to its holding pouch on the platform, that is his cue to back the helicopter away from the structure. In this particular occurrence, the procedural tasks got out of sequence, and when the pilot saw the ground cable and clamp in its pouch, he backed the rotorcraft away. The lineman, still tethered to the rotorcraft, was pulled off the structure, and the lineman's choice of safety tether attachment point on the rotorcraft gave way under his weight, causing the fatal fall.

NTSB Probable Cause Narrative

The lineman's failure to use the designed attachment point for securing his safety harness to the helicopter, resulting in overload and failure of the component he did attach to. A factor in the accident was the lineman's failure to follow exact sequential procedures for performing the in-flight transfer from rotorcraft to structure, resulting in his being dragged off the structure by the retreating rotorcraft.
