Not trying to argue here but this claim is absurdly inaccurate about no accidents

Is it though? Can you then tell me how many accidents happened with 737s and A320s during the take off phase since the 2000's in third world countries? And with 100% casualties?

You are conveniently omitting the part that the uncommanded pitch down is not the only thing going on. Air speed disagree, stall warnings, stick shaker. And I guess other 737 drivers disagree with you, as expressed in PPrune, this forum, Anet, and others. It is a bit worrisome when pilots are so split in this.

Point 3 is true that bad input data can happen but Lion air knew they had a problem with the sensor and did nothing.

And you are shifting the focus, like most like to do, and ignoring that that same scenario can happen to anyone with one bird strike.

Let me add why a 200hr first officer makes a difference. At least in the US, first officers must have at least 1500 hrs and a type rating in the aircraft which means they have been trained and tested (maneuvers and systems knowledge) to the same standards as a captain so their knowledge and skills are invaluable in an emergency situation. Some situations need 2 fully knowledgeable brains to lead to a successful outcome and 200hrs total time is slightly better than a passenger from 32F coming up to offer advise.

You do know the 1500h rule was only implemented in 2013 right?

I don't think anyone is denigrating the pilots in this situation, just pointing out that the it would have been better to have both pilots "seasoned", which might have led to a different outcome regardless if the airplanes control systems were a contributing cause.

On another board a pilot commented that particular airport is a "Capt only" airport. Not sure what that exactly means.

There is no logic behind it, but the accident in 1991 here in COS sticks with me. I rarely think about it, unless I’m making the approach from the south. Doesn’t matter about the aircraft type, whether it’s a small single engine, a UAX airplane. I arrived about 30 minutes after the accident as simply a drive by and will never forget it. Lost 2 people that I didn’t know personally, but my siblings did.

All of that said, I want nothing to do with the MAX until this is resolved.

I thought the accident in 1991 was attributed to wind shear? I didn't know anyone on that plane but knew someone who narrowly missed being on it due to missing his connection at Stapleton. I remember flights into COS for the next year seemed to be like carrier landings ... every one I was on came in to the airport fast and hard.

Apparently that means the Captain is required to be on the stick for take-off and landings at that particular airport. So, that would have precluded the FO from being in control. Regardless, whomever is at the stick needs help in an emergency. A seasoned pilot by your side is always better than one who is not.

The MAX (both -8 and -9) has now been banned by EASA from all European (Common Aviation Area) airspace.

Not up to speed on all of this, but does this effect UA? And if yes, how and to what extent?

I will just note that this is ALL models - both -8 and -9 - of the MAX. Given that they have the same control system, and that the -8 represents most of the flight hours so far (and so much more exposure to identify a problem) this is probably the only reasonable decission, as there does not appear to be any suggestions of a reason specific to the -8 for problem.

And I highlight again what I posted above from the WaPost, Chinese authorities expressly said they had reports from Chinese pilots of issues consistent with the failure mode suspected in both crashes. A large part of these investigations is identifying other similar events that did not result in crashes.

Wouldn't that mean that the copilot shouldn't do takeoffs and landings at that airport?

You may be right. Based on this line from avherald it could be read either way: "The captain was with Ethiopian Airlines for 9 years and had about 8000 hours of flight experience, a first officer with 200 flight hours assisted[...]".

I’m surprised UA hasn’t quietly sidelined their 14 Max9. It isn’t a network workhorse like their other 737s.

UA doesn't fly the MAX in Europe.

Your implicit trust in statements by PRC authorities who are currently engaged in a trade war is noted. If these statements are accurate, those authorities should have acted long ago.

How Many Stability Accidents Has the 737 (all series) Experienced
 
I remember the 1994 accident of USAir Flight 427 where the 737 fell out of the sky. Was planning to take the flight in 2 days on the PIT-PBI segment. The day I took the non-fatl segment the number was changed to 2427.

That's hard to say as it's possible to take it either way. They could be lobbing a grenade or maybe they held off until now as they didn't want to fan the flames during the US/China negotiations. I'm not smart enough to know.

Closely related to that was UA585 which crashed because of the same reason on approach to COS.
