Having taken shelter under my nomex umbrella, I would like to say how delightful it would be to discuss the mechanical architecture of the THS (and elevators). Without prejudice, a discussion of the power supplies, articulation geometry and other would be a fantastic foundation for understanding the ultimate upshot of the explanation for the lack of ND re: THS on the way down. For the moment, PE is the working theory.
Fine, no bad. Lacking airstream damping consistent with cruise speed, did the jack overspeed? Did it, not encountering a back lash from the THS, shift thrust faces on its screw and lock? For the partisans: No offense, none intended, and save your energy for later, eh?
