I agree the training was lacking but it seems the 3d world airlines
had all the trouble, in spite of flying the max a fraction of what
airlines like Southwest were flying.

Which again is totally unfair. The AOA sensors only failed on two
aircraft, LionAir and Ethiopian Air.

That is certainly what lead to two crashes but I haven't really heard
anyone say those were the only two AOA sensor failures.


I had the impression there were other failures but for competent pilots
it was just another day on the job.

I'll bet it scared the heck out of even the "competent" ones when it
first happened - - -


It didn't happen on any other flights, there were just three flights.
How many AOA sensors would fail in a few hundred planes that are just
a year old?


I would expect it would show up with the airline that has the most
maxes and flies the most miles in them, not two in some obscure
airline in the 3d world with very little flight experience in them.

Trumpesque style America first and only America, screw everyone else.
All airlines didn't have a lot of experience with the Max, it had
only gone into production about a year before the crash and only a
few hundred had been delivered. Apparently Lion Air is not obscure
to Boeing:


Lion's Sha Lion Air Orders 201 737 MAXs and 29 Next-Generation 737-900s

With leonine boldness, Lion Air has pounced on the opportunity to extend its 737 dominance far into the future. The worlds largest 737-900ER operator recently finalized a record-breaking order for the 737 MAX. Lion Air is also now the global launch customer for the 737 MAX 9.

The firm order includes 201 737 MAXs and 29 Next-Generation 737-900s, the largest ever commercial airplane order for Boeing. Lion Air was the first airline in Asia to commit to the 737 MAX. With the finalized MAX order, MAX success is sure to follow. Hakuna matata!





... unless this is some kind of maintenance issue that they have been
slow to point out.

Hard to imagine it's a maintenance issue on a plane that's only a couple
months old and the issue is a simple vane sensor.



It is also possible that a good pilot would have caught the failure
early, mitigated the problem and continued on his way without scaring
the hell out of the passengers. Maybe they just spent the extra few
bucks and bought the light that indicated the AOA failure.

Again, any such incidents are not just ignored and not documented.
They would have been logged and reported. Even if a plane had the AOA
disagree light, there is no indication it would have made a difference.
Again, there was no explanation of MCAS in the Max manuals, no pilots
were aware of it or trained on it. They didn't know an AOA sensor
could shove the nose down, no way of knowing how an AOA light would
have factored in to what they might or might not do. And again,
the Ethiopian crew followed the exact procedure that Boeing put out
AFTER the first crash. It didn't work, the co-pilot was unable to
move the trim wheel. Are pilots flying for American carriers stronger?
