I would like to address this short reply to You as it appear that You can grasp details, principals and the greater Picture.
It looks to me that the Max is certified under false pretenses , or self certified as FAA has let Boeing do most of it in house!!
The Max is unstable and not airworthy with out the MCAS!
I doubt the MCAS is fit for purpose, as I have always said the 737-800 even , has a dangerous pitch coupling.
I predict that in the not so distant future the Max will kill again if only a software fix is provided,this time due to a full stall, spin as the MCAS is inadequate.
I could be wrong, but 10 000hrs 738 plus 2000hrs sim tells me this bird is one step to fare and the Max is clearly two steps past stable and safe.
Simple as that!

PS
Do not take my word for it.
MOT in Canada is going to look into the FAA certification they excepted AND are doing their own certification on any fix.
Aircanada has grounded all the Maxes to 1 July
Lets hope its this July not 2020
