Bernard Gray has been banging on about it. It is one reason he wants to get the private sector more involved – he hopes that culture doesn’t exist there, in the sense a company will have no qualms about submitting a costed proposal to make an aircraft safe or operationally effective at a fair and reasonable cost
I think its generally too early to promote (or otherwise) the changes that Bernard might make. One thing is for certain, the pitfalls he is trying to avoid in improving things are huge - e.g. in terms of adequately & effectively managing the supplier base. Sure there are things that are bad today, but there is still a risk he could make it even worse!
