On 7 March 2023 an ATR 72-200 crew discovered the rudder was extremely difficult to move during the landing flare, but nosewheel steering was enough to prevent a runway excursion after touchdown. The aircraft was found to have a history of rudder stiffness, which a recent attempt to rectify had not resolved. The crew knew of this and decided that despite a somewhat unsatisfactory preflight rudder check, absence of any significant crosswind component would permit the flight. Investigation attributed stiffness to corroded bearings in the rudder actuation system in the presence of excessive undrained moisture.
