I think the point here is that the existence of this report is not intended to explain the crash. Rather, it is evidence of very serious "Organisational Fault", a verdict or contributory factor open to the Board of Inquiry. They failed in their duty to address this factor, despite hearing detailed evidence of systemic airworthiness failings.
To me, this aspect is shameful. Having listed a raft of problems, any reader of their report is left asking "So, what did you do about it? Who is responsible and why are they doing nothing?". As ever, one must ask who this failure protected. (Haddon-Cave provides the answer). None of them were ever interviewed by any inquiry. I wonder what they'll write in their next letter to The Times?
