Below is a quote in the summary of the investigation the ATSB. The words used by ATSB give rise for concern about the level of knowledge in ATSB.
In addition, the ATSB cautions pilots and operators to conduct hot refuelling in accordance with the aircraft flight manual and Civil Aviation Safety Authority regulations. Further, leaving the flight controls of an operating Robinson Helicopter Company R44 helicopter to conduct refuelling increases the risk of a loss of control.
As far as I can remember, the manufacturer of the R44 and the R22 prohibits pilots exiting the helicopter with the rotor turning.

Does the ATSB know about these publications???? It appears not.
Contrary to what some in the industry believe or have been taught and the inference from what the ATSB have written, "hot refuelling" of a helicopter requires two people, the pilot at the controls and the refueller.
