He didn't have a helmet or so much as a seatbelt in the helicopter. The tail rotor flew off, hit the main rotor at a high speed, which knocked him sideways, out of the fuselage. It was at this point his head came into contact with the spinning main rotor, likely killing him instantly. A seatbelt seems like it would have saved his life.
