I know its hard going if you've no experience of airworthiness, which is most here, but my advice is to read the evidence to Hadden-Cave and Lord Phillip. Tuc and Chug are absolutely right. If you wanted to avoid most of these accidents and correct the system the answer is the same. The rules are not difficult to understand, just implement them. Just because an issue seems complex doesn't mean the answer isn't simple and staring us in the face. Seems to me it is something else that is upsetting a few folks. Tuc mentioned one of them, that few met their obligation to report failures. Another is the shock we feel at being let down by such senior officers. Evaluator's is one of the few posts that mentions this unmentionable.
