I sense a bit of an obsession about trim runaways …c’om guys, those have been with us since ever and airplanes were not just falling out of the sky because of trim runaways (not that they did not happen) . My 40YO autopilot has at least three straightforward ways to stop the trim from running away from you, plus a couple more not so straighforward…

The issue was reported late 2022 …. this is just the resolution:
