Well, at least the Mk3 wasn't rushed into service, with poor Flight Reference Cards, spurious engine fail captions, unrequested engine shutdowns or various flight restrictions - making it less capable than the version it was supposed to be replacing.
Something, perhaps learnt as a result of the accident on the Mull.
That matter still goes on, nearly ten years after the accident!
