Dave The Rhino writes clearly. The second sentence of 25.203(a) would be a sticking point with the design as disclosed to date, 25.173 is more general in scope. The disclosed logic indicates that the problem arises in turning stalls, but the permissible pitch characteristics is in paragraph (a), and MCAS is definitely working in that area. That particular sentence is the reason for having stick pushers in some designs, most often T tail aircraft. In the normal course of affairs, this would occur around stick shaker so would not be readily observed by a pilot, there is enough happening to keep them busy at that point. That makes some sense as to why the OEM went that way, Adding a stick pusher would have been a notable change to the design, and stick pushers have the same capability of giving an out of trim condition unless deactivated.
