Another turn the wrong way issue that happened was on the early versions of the 737. It would cause the rudder to go hard-over to the other direction it was commanded. It happened so hard it was difficult (if not impossible) for a pilot to counteract it using the pedals (they would basically have to stand on the pedal). It killed at least 157 people. The culprit in this case iirc was a combination of a flaw in the hydraulic cylinder design with large temperature swings. The story of the guy who finally figured it out is a fun one. https://en.wikipedia.org/wiki/Boeing_737_rudder_issues https://en.wikipedia.org/wiki/Boeing_737_rudder_issues
