I don't know what their reasons are, but for some reason they believe that this is limited to the -8 and -9. Is the MCAS installed only on the -8 and -9 but not on the -7, or any previous models? I don't know, just asking the question. It doesn't appear that there's a lot of information about this MCAS.
Trying not to be pedantic. If MCAS is “Manual Control Enhancement”, but is uncommanded, (automatic) does that make the nomenclature oxymoronic? To claim it is not oxymoronic is to require an “assumption” on the Operator’s part? In the absence of written reference, I would say it does. Isn’t that the basis for the AD?
