29 October 2018: Indonesian carrier Lion Air Flight 610 on October 29 crashed into the sea soon after takeoff with the loss of all aboard, apparently due to the erroneous data from a faulty Angle of Attack sensor, which caused the MCAS (Maneuvering Characteristics Augmentation System) to assume the plane was about to stall, which activated the downward force on the Stabilizer Trim to get the nose down.

As 737 MAX’s return slips out to mid-February, FAA boss tells Boeing CEO to back off predictions
In a starkly direct rebuke to Boeing, Federal Aviation Administration (FAA) chief Steve Dickson met with company CEO Dennis Muilenburg at FAA headquarters in Washington, D.C., on Thursday and told him to pull back on public statements about an imminent return to service for the 737 MAX — a milestone that people close to the details now say is unlikely to happen before mid-February.

Finally! He was the Captain when Boeing lost its course, shifting its priorities from excellence and safety to cost reduction without context.
Boeing CEO Dennis Muilenburg SACKED by the Board of Directors.
United has scheduled MAX aircraft beginning 6 June 2020, hoping the MAX recertification will allow them to fly the MAX during the busy summer season. AA hasn’t yet announced a date that far out, but it probably can be expected. The entire recertification program hasn’t been finalized, much less accepted by the various world aviation authorities. Once that occurs, modifications can occur, “de-mothballing” and flight testing can begin.
Boeing CEO Dennis Muilenburg SACKED by the Board of Directors.
Boeing said in a statement that its board of directors “decided that a change in leadership was necessary to restore confidence in the company moving forward as it works to repair relationships with regulators, customers, and all other stakeholders.”

I was told months ago by friends in the local Grey Eagles (retired AA captains) their collective opinion was Boeing was concentrating on an electronic fix when what is needed is a more basic mechanical change to compensate for the unforeseen center of gravity problem. Meaning they agree with the original chief test pilot. (Funny thing--whatever happened to him after he made that recommendation? Since apparently he is long since out of that position). Their industry sources are active AA pilots.
Didn't think too much about it when first repeated to me, since they are still McDonnell Douglas loyalists with a long-held distrust of over-automated flying. But time is making them look wise.

More bad news for the MAX, this time a separate issue...
FAA checking potentially "catastrophic" issue with 737 Max wiring
FAA checking potentially "catastrophic" issue with 737 Max wiring
The Federal Aviation Administration is looking at a potentially "catastrophic" issue with wiring that helps control the tail of the 737 Max, CBS News has confirmed. The safety review was first reported by the New York Times and confirmed by Boeing officials.
It grew out of an FAA request to Boeing for an internal audit to confirm the company had accurately assessed the dangers of key systems in light of new assumptions about pilot response times to emergency situations.

AA flew the L-188 Electra (I flew on a number of those), which was grounded because the wings occasionally fell off (Google “whirl mode” and Lockheed Electra to learn how that worked).
When the Electra was modified and recertified it, AA renamed it “Super Electra”. So, “737 Super”, “737 Advanced”, “737 AT (Advanced Technology)”, etc. are certainly possible.,

I agree that this is most likely overblown, but it just comes across as sloppy. They said that it might also apply to the NGs, which suggests that it's not THAT serious (since they haven't been falling out of the sky) but... I've said it before and I'll say it again: As an engineer with a couple of decades of experience who focuses on quality first, I can see the there are cultural problems at this company that cause the focus to be on speed over quality. I can see it even from the outside; it was obvious even before the whistleblowers started coming forward.
The change in leadership is a good start (because, eventually, this has to come from the top) but it will take a long time to change the culture. It most likely involves changing KPIs, which is not an easy thing to do (you need to evaluate performance based on different criteria). It takes a while to "train" people to get used to the fact that they will be judged based on new criteria. People who are used to being told "good job" when they finish fast will need to adjust to being told "good job" when they actually do a good job, rather than a fast one.

@VegasGambler, as someone who worked with many engineers and cultural change, I can’t agree more.
Meantime, AA has reached a settlement with Boeing for losses related to 24 AA MAXs being grounded. Link to Bloomberg article.
The numbers are confidential, but AA has earmarked ~$30 million for employees as profit sharing.

The companies are still in talks over compensation for damages beyond 2019, American said in a statement Monday. The Max’s absence since March shaved at least $540 million from American’s 2019 pretax income, the airline has said, and the benefits from the confidential settlement with Boeing will be received over several years.
