Peter,
There is certainly a Safety Notice, but that is not a limitation. You will also be aware of CASA Regs which allow a pilot to leave a running helicopter under certain parameters, such as skids and lockable controls.
After an accident, of course, the interpretation of the Safety Notice then enters the domain of the legal profession
