What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
This part 91 flight was intended to be a supervised solo in the traffic pattern. Reported winds 290/05 knots. Student and CFI performed three dual traffic patterns to the Riverside airport (ral) runway 16 helicopter practice area. The student pilot and her CFI practiced several takeoff, hover, and landing maneuvers in preparation for the student's supervised solo flight.
Prior to leaving the aircraft, the CFI reminded the student pilot about the lateral CG shift when the right seat passenger is no longer in the seat. Note: the cfi's weight was approximately 220 lbs at the time of the accident.
The CFI left the aircraft to wait at an area on the VOR antenna walkway 50 yards west-northwest of the takeoff point. The CFI observed the student pilot start to lift the aircraft into a hover. At this point N269C rotated rapidly 180 degrees to the left before setting down firmly.
The aft cross beam and left side drag on the landing gear were damaged. The tips of both tail rotor blades made contact with ground contact and were damaged. The other tail rotor rotating components appeared intact and undamaged. N269C remained upright with no injuries to the crew.
