What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Instructor and student were climbing out in an R-44 helicopter to practice right traffic maneuvers at Linden Airport. Passing 200' the student said he felt a vibration, then the "low rotor/rpm horn and light" came on. The instructor took control, sensed the loss of power, and auto rotated into a vacant construction site. The site was muddy and the leading edges of the skids dug into the turf, rocking the craft fwd and back. The turning/trailing rotor blades contacted the rear boom and virtually severed it (mast dampening). No damage to persons or other property. It is viewed the instructor acted prudently. No enforcement action planned.
