This is all fairly irrelevant to the fact that the safety procedures themselves seem unjustifiable. How could the FAA have raised questions if they weren't even doing the testing? Nobody in either the article or this train of comments has suggested that it was unreasonable to assume pilot error after a single crash. The problem is the oversight process which allowed it to be certified in the first place. The airline industry isn't responsibly reacting, they're reacting after trying for quite some time to ignore the problem because it's becoming increasingly obvious that they and the FAA have been horrendously negligent, and ignoring it isn't working anymore.
