As you have said:
As I have pointed out, the certification documents for all commercial transport aircraft contain one large safety case.
There is a systematic hazard analysis of every system on board and it is accompanied by a demonstration that the requirements of the risk matrix are satisfied.
Airworthiness certification is obviously very effective.
I'd welcome your views on this where those practices seem to have been less effective:

really would love to know what Shell Management will do in his Safety Cases in regard to this recommendation:
...prohibit commercial operation of Category A transport helicopters over water when the sea state will not permit safe ditching and successful evacuation.
