Another day, and another MAX issue surfaces in the wild.

tl;dr: 06FEB2024: on landing rollout at EWR, the crew reported that the rudder pedals were "stuck" in their neutral position and used nosewheel steering to maintain runway centerline.
09FEB2024: UA orders a test flight on the aircraft and is able to duplicate the malfunction.
28FEB2024: Collins Aerospace examined the rollout guidance servo and found that after being "cold soaked" for 1 hour, "the servo's output crank arm was significantly beyond the specified design limits" ... which "would prevent the rudder pedals from moving as observed during [the incident]."
