Personally I don't think 4 days suspension is the end of the world if the wing came off.

There are a lot of business owners who would disagree with you. There was a great deal of evidence pointing to the cause, and a structural failure "just because" was not on the list. The grounding has caused incredible distress to the business owners and employees of the operators of these aircraft, not least because it was accompanied by so little information.
I asked CASA to eliminate what turned out to be the primary cause and their response was along the lines of "Of course we looked at that, you must think we're stupid, it was definitely something else". That our #1 theory has turned out to be the #1 cause says to me that the grounding was unnecessary and that there needs to be some jobs reviewed at Fort Fumble.
