Obviously both groups will be subject to any AD issued to require implementation of post-MCAS mods, but that's a different issue.
I beg to differ : both category of aircraft have been built and flown under the same C of A. The fact that some were to be delivered - as opposed as had already been delivered - doesn't change the issue.
Where do you draw the line ?
Some of the 'undelivered' aircraft are already owned by client airlines.
Or do you make a difference because some have already flown passengers ?
