Safety shouldn't be a commercial issue but it is.
In the case of the distressing Hughes / Kenyon case, it may be that CAA fondly hope that companies will happily implement the recommendations without it being mandated. The fact is, that in a harsh commercial world many will be blocked from doing so by their own resident beancounters. Mandate it, everybody has no choice, the cost gets passed to the customer - but evenly across the board so the commercial operators (and their beancounters) aren't all that worried because it maintains a level playing field.
It shouldn't be that way, but it is. It's the reason that in other spheres I'm known as an opponent of too much reduction in regulation at the lowest end of GA, because it gives a commercial advantage to those prepared to cut the most safety corners. The CAA's approach to the Hughes safety issues could be regarded in the same light.
