It's interesting how some countries and airlines (particularly Korea and Australia) have been very forthcoming with factual data and commentary on the check and repair process, yet its radio silence from many others. Yep. Silence from China. Thousands of high-mile, short-hop 737s operated by low ma...Jump to post

So will these fixes solve the underlying problem that the MAX is an unstable airplane at baseline? So it'll still have a tendency to stall more often than comparable airplanes, right? So what's the software going to actually fix? I am not sure that is entirely fair. The bigger engines mounted forwa...Jump to post

[*]There are two follow up questions which are interesting: The first is what would an airline during a heavy inspection after 25,000 cycles if there are no cracks at that time?

Agreed, if Boeing is going to emerge stronger from this crisis it needs to completely change its culture. This needs to happen with a firm message from the board, something stronger than removing the CEO as chairman. There is desperate need for a new CEO who can make Boeing great again !!!Jump to post

I realize it is still early but wondering after the initial inspections, what is going to be the defined interval for checking the PFs and starting after how many cycles? I would assume it gets made part of the rolling C-Checks which many airlines use for the 737NG. And should it really be cycles as...Jump to post

Questions for a pilot:
Does the stick shaker go off on one side or both at the same time? How hard is it to fly the plane with the stick shaker going off?
A question which I have not seen specifically in any post or report. Who was flying the plane? I am assuming the captain as he was significantly more experienced. But at the same time he was the one with the issues on his side and it must be very hard to fly with the stick-shaker. Is this the case? ...Jump to post

One crazy theory is that the fo who had limited experience panicked and fearing mcas trimed the aircraft in the opposite direction, that is to a nose down attitude.

I do not know the reason why it may not have been in the flight crew training but MCAS is performing a similar function as speed trim. This is not a totally different system.

Questions.... There is mention in some articles about a needed software upgrade to the MCAS system: - How long might this take to accomplish and then to implement? - What might this look like? Is it as simple as shutting down MCAS when you have unreliable AoA or when the pilots pull up on the yoke?Jump to post
Again, interesting to note the AoA instrument issues on the last flight prior to the accident as noted in the article below.

I had thought that the issues on the prior flights were only related to the Air Speed Indicator.
