That would make it a Lion Air training failure. Well, how could they train for it, when Boieing conveniently hushed over such a significant change, because it was commercially expedient? Until the Lion Air crash the airlines and their pilots didn't even know that such a system is in place. According to an AA pilot the entire training consisted of less than an hour presentation on an iPad, in which the new behavior wasn't mentioned at all. Add to that that Boeing offered a paid upgrade which at least would make pilots aware that the system malfunctions. This paid upgrade sounds a bit like "Nice plane you have here, would be a shame if it crashes" No matter how you look at it: Boeing displayed despicable behavior in this whole sorry mess. Behavior which comes back now to bite them badly. I don't disagree with your reasoning, for what it's worth. I just think there really should be a special place in hell for the Boeing executives who allowed this to happen. Especially after the first crash.

Again, unless I've missed a statement, we don't know if Boeing has tested for this case internally. This case being "pilots untrained and unfamiliar with the MCAS system recovering from a catastrophic systems failure / error". They are at fault no matter what though from straying from their long held principle that the pilot has the final say on control of the aircraft. Inputs from the yoke and throttle levers should always supercede the computer.

The pilots could have been trained to understand all the control surfaces on the airplane and how to identify their configuration. From what is reported about the Lion Air crash it sounds like the pilots may not have sorted out what the stabilizer trim was set to and what to do to correct it. Hopefully that is not the case as such a situation would be a glaring problem with pilot competence.
