Good points KG. One of the big problems I see, is the regulation and legislation is not directly proportional to the risk's or to actual safety incidence.
let me point out 2 recent safety cases.
1. Robinson helicopters fuel tank issues. Involved multiple deaths around Australia and the world. The issues were known by CASA and the manufacturer. A soft " do as you see fit" modification was
'encouraged' but not made mandatory, until the horrible fiery deaths racked up to an unacceptable level. Once pushed hard, CASA finally made the changes mandatory.
2. Jabiru engine failures. Reliability of the engines was questionable for a variety of reasons, and without consult with industry, a heavy handed, over the top approach from CASA followed. With extreme reluctance
to furnish the industry with any detail. yes, of course there were issues, but at the time no deaths were directly attributable to the design' Flaws".
So on one hand we had multiple people, burned alive due to a KNOWN and DOCUMENTED problem with design. The regulator did nothing meaningful until the chared bodies piled up.
On the other hand, we had no fatality's, very few injuries, all be it a design issues that was known to cause engine problems.
The mind boggles when one tries to imagine both cases being handled by the same regulator.
The legislation needs to be proportionate to the ACTUAL safety case it attempts to control.
