NTSB Narrative

One witness reported seeing the helicopter transition to the west with "low power indications" and "multiple yaws." The helicopter settled to the ground and then struck a fuel trailer near the taxiway. According to the pilot, he transitioned the helicopter to a hover and taxied adjacent to the taxiway. When he attempted a forward takeoff from the hover, the "low rotor rpm warning sounded, the helicopter lost lift," and he performed a "running landing." He stated that there were no mechanical malfunctions or failures with the helicopter during the flight. The Federal Aviation Administration inspector confirmed that there was nothing mechanically wrong with the helicopter. One tail rotor blade and the stabilizer separated from the tail boom. The pilot did not maintain control of the helicopter during the takeoff resulting in low rotor rpm and impact of the fuel trailer during the running landing.
