The waters were muddied long ago in MoD when Director Helicopter Support, Director Helicopter Projects, Director General Air Systems 2 and the Chief of Defence Procurement all ruled that engineering and safety decisions made by engineers, within their delegated authority (and agreed to by Boscombe Down and the Aircraft Design Authority), could be overruled by non-engineers; but if anything went wrong the engineer should be blamed.
This precise scenario occurred before and after a fatal crash in 2003, and to this day the MoD maintains the engineer is to blame, despite the records showing he issued a directive to make the aircraft safe, only to be overruled.
The MAA are so busy faffing around reinventing wheels they haven’t got round to addressing this problem yet. Perhaps this Greek tragedy will give them a push.
