What happened
The accident occurred during a local training flight intended to prepare a private pilot student for a commercial certificate check ride. The helicopter was operating in a rural area with overhead power transmission infrastructure. During the departure phase from a specific clearing site, the aircraft encountered a static line belonging to a power transmission array that crossed the operational area.
The impact with the static line caused the helicopter to lose controlled flight. The aircraft subsequently entered an uncontrolled vertical descent. It impacted the ground approximately 600 feet beyond the location of the transmission line. No further details regarding injuries or specific aircraft damage are provided in the source record.
The investigation
The available source text does not contain specific findings from a mechanical examination or post-accident inspection of the helicopter components. The narrative focuses solely on the sequence of events leading to the impact with the power line and the subsequent ground collision.
Findings
The primary factor in this accident was the helicopter's contact with the static line of the power transmission array during departure from a clearing. This contact directly led to the loss of control and the vertical descent that resulted in the final impact site being located 600 feet beyond the wires.
