The stated aim is to prevent recurrence. The actual aim is to conceal the truth.
...and there in a nutshell is why Air Safety is unsafe in the hands of the MOD, or any of its agency or Service subsidiaries. It lies, steals, and cheats to conceal incompetent and illegal activity. That is something that may be expected and understood, if not condoned, in politics and in the corridors of power. It is not understood nor accommodated by aviation. Because of it people die, 63 in fatal accidents considered in this forum alone, possibly becoming 65 with the subject accident of this thread.
Covering up by pinning the blame on subordinate JOs, SOs, or even 1* VSOs, has been the disreputable policy of the Star Chamber to date, in order to mask the culpability of its own members. In doing so it has severely undermined the security of this country and sullied in particular the honour of the Royal Air Force. It has to stop. The MAA and MAAIB have to be made free of the dead hand of the MOD and of the High Command, and separated from each other in order to do their respective and very different jobs.
Self Regulation Doesn't Work and in Aviation It Kills!
