Without even speculating, it's clear that the unfortunate pilot did not get hit by the tail rotor, even though the first news report did imply as much. The NTSB report does not specify.

It's clear to see that the pilot is lying out near the edge of the rotor disk at about amidship on the pilot's side. The t/r on the 47 is on the right, so the helicopter would have had to jump up into the air and move laterally for things to be where they ended up.
I find it curious that it was reported that the pilot thought he had some problem and set the ship back down after takeoff. Unless this comes from a radio transmission, it is pure speculation. Looking at the place where he did set down, and looking at the broken spray boom, I'm a little skeptical that the landing was intentional.
Sad accident.
