tucumseh,
the negligence in releasing the aircraft to service against a fabricated CA Release and Release to Service. Also, the related failure to demonstrate in the Master Airworthiness Reference that installed equipment performance had been properly assessed and established (pre-requisite to determining Limitations) and, of course, the failure to provide proper FRCs (Instructions) and training. There is more, but all trails lead back to the Release process being hasty, ill-considered and premature.
This is what it's about - no case has to be proved, or to be represented. No new evidence needs to be sought to overturn this 'finding'. We are where we are because the MOD has been able to ring fence itself and not be held to account. Well, the World has moved on - if this 'case' was put in front of a Judge and 12 true men - we all know what the outcome would be.
Then the process of identifying those individuals who were, themselves, negligent - re the above - can commence.
