At the risk of looking like a hawk (not to mention a tiresome bore) on this thread, I think that it's fairly obvious that there is nothing wrong with the type concerned as long as pilots fly it as their training prescribes.
Yes, if aircraft are prone to pieces falling off then we should take notice - I don't think anyone would disagree with you there. I'm sure that there are studies galore on composites and water retention that could be used by people to prove things one way or another, but the fact remains that in this incident, the craft was flown outside its safe parameters before any problems were recorded, and it can be proven with very little doubt that flying outside those parameters in the way that this craft was flown would have caused the damage that led to its loss.
