That's a great article and objective precis of the events and probable causes of the accident.
It doesn't paint Island Helicopters or their chief pilot in a very good light and it also highlights the shortcomings of box-ticking safety assessments which are meaningless unless there is 3rd party objective oversight of such assessments - unlikely to occur in a small outfit I would suggest.
Additional bureaucracy does not in itself bring additional safety and is often ignored because it is an unwieldy and time-consuming process - not always suited to an aviation environment where quick decisions are needed in many cases.
