Looking at the video of the crash site, the tail rotor boom looked like it was with the rest of the fuselage. I could not tell if the actual rotor was still attached, but I’d guess it wasn’t. I’m guessing that if it hadn’t flown off the rotor assembly at the time of the accident, it may have broken apart at the moment it crashed.
One of the rotor blades, that is. Too soon to tell.
