What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot reported to ATC that "on landing runway 30L a bolt that stabilizes the rotor blade was dislodged. When powering up the helicopter for departure, there was a vibration cause(d) by the rotor blade being out of balance from the loss of the bolt. The rotor blade sustained some damage, from being out of balance".
ATC reported that the pilot had been practicing auto-rotations.
A ramp inspection performed on the aircraft on 12-4-13 found that the tail rotor was damaged. Damage was to the tip of one rotor blade predominately on the leading edge and the blade showed buckleing at the mid point. The other blade was damaged on the tip toward the trailing edge. The tail skid or 'stinger' had fresh marks on the bottom side. All of these are consistant with rotor strike.
6-2-14 The owner stated that the aircraft had been taken by truck to a northern California repair station.
The director of maintenance at the repair facility reported that the damaged parts, including the tail rotor, tail boom, skids, and cross strut.
The owner said that these parts are so hard to find that he may just part out the aircraft.
