I'm very familiar with what happened with AA191. I've probably read more on that one crash than I have on any other single airline incident. The fact was that the EA was issued on a procedure that was not safe, and the mechanics, the last line of defense, signed off on the work. Granted, hindsight is always much better than foresight.
But you misunderstand my point, as you have for several months now. I don't doubt that there are issues with MAE, nor do I doubt that the contract with MAE is written so as to have safety take a backseat to money. That should be stopped. But the solution of bringing the work back in house is not the only viable solution.
