Incident Overview
During a training flight, a certified flight instructor (CFI) demonstrated a right circling confined area approach in a stand of oak trees. After flying over the area, the CFI instructed the dual student to perform the maneuver. The dual student completed two successful confined area approaches to a hover.
Departure and Collision
Following the student's successful maneuvers, the CFI assumed control of the helicopter. The CFI then departed straight out over the lowest section of the trees. Seconds later, the helicopter struck power line wires that were partially obstructed from view by the trees.
