It doesn't say in the above extracts how it was established MoD did not get the information. Is this an allegation by MoD, or has MB accepted it as true? All the MB guy has said is he wasn't there at the time, which is not the same as admitting the info was not passed on.
It would certainly be a handy "out" for MoD if true. But in my experience, in that period, it is equally, if not more, likely that MB has passed on the info properly and it has not been disseminated correctly; largely because the mechanism was run down in the period 1990-on. Bear in mind the same system allowed captured Argentine publications and maintenance data to be used on Chinook, which says it all.
The key process is one of informing "affected parties", and any reputable company keeps this data up to date and permanently embedded in the necessary "advice notes", or whatever. For example, in a MF714/5. The MoD department that oversaw and policed this fundamental airworthiness principle was disbanded in June 1993, and not replaced in any shape or form. Thereafter, it became pot luck whether the Engineering Authority, Pubs Authority or Project Manager was on the ball. As Mortmeister correctly implies, some would know and others wouldn't.
Even if, somehow, MoD was left off distribution, so critical was the issue that MoD's resident QAR would be climbing all over them. That is, if it happened before these posts were cancelled as a savings measure.
There is a lot more to this but I'm certain the MoD won't trot out any witness who can dissect the issue, and the Coroner won't know what to ask.
