AFAIK, there was evidence of a fault with a non-critical component: a redundant pressure regulator. There is no clear evidence of any reason to believe that this was evidence of something potentially catastrophic. This is the totals classic case of hindsight being 20/20; non-critical components go out of order all the time. Thats why critical is very much not a judgement call but a carefully assessed list of components.
Very obviously, the list of critical components will need to be reassessed in light of this, and I would bet dollars to doughnuts that that reassessment is part of the reason the FAA is taking their time approving an inspection procedure that would allow MAX-9s to fly again. And the NTSB investigation will surely shed light on whether AS mechanics should have recognized warning signs based on this pressurization system light. But this really seems like something we dont have the evidence to speculate about here.

"The FAA issued a "Safety Alert for Operators" Sunday disclosing some airlines have conducted additional inspections on the 737-900ER mid-exit door plugs "and have noted findings with bolts during the maintenance inspections."

Anyone else find the “term “findings” opaque?
Anyway, more details here:

Just came here to ask the same after reading the original FAA document:
https://www.faa.gov/media/74751
Discussion: The Boeing 737-900ER mid-exit door plugs have an identical door plug design to the 737-9 MAX. As part of their Safety Management Systems, some operators have conducted additional inspections on the 737-900ER mid-exit door plugs and have noted findings with bolts during the maintenance inspections.
Recommended Action: Operators are encouraged to conduct a visual inspection to ensure the door plug is restrained from any movements through the two (2) upper guide track bolts and two (2) lower arrestor bolts. Please refer to the Aircraft Maintenance Manual and 737-900ER Fuselage Plug Assembly Maintenance Planning Document (MPD) for more information, regardless of if this inspection has been conducted under the existing maintenance program prior to the EAD. As Operators conduct the visual inspections, they are also encouraged to report findings to their certificate management office.

pretty standard language for recommended actions ... if the inspection was required/mandated by an AD or EAD, the reporting would likely include something like "findings and corrective actions taken"

Boeing Whistleblower: Production Line Has "Enormous Volume Of Defects" Bolts On MAX 9 Weren't Installed - View from the Wing
Although this is very specific detail for a commenter.....but im sure the FAA/NTSB wants to talk to this person and getting thier IP address to find them.....
Im just curious if the 900 does have some issues found....but if the overall quality with Boeing production is of suspect....what happens to recently delivered 7M8 and 787s? How do you address the overall lack of production for an entire manufacturer?

If your TPMS sensor says your air is low but when you manually checked it, it's fine, are you going to stop driving the car immediately, or are you going to schedule a service request to get it looked at later this week? If the tire later blows out, is it entirely your fault that you didn't stop driving the car immediately?
Or did they reset the TPMS sensor three times without bothering to even schedule a service request, much less have someone actually look at it?

It is along the lines of what I wish I heard from Alaska.

If UA cancels their order, queue the headline "Alaska orders additional MAX10s at a discount"
