On 7 March 2023 an ATR 72-200 crew discovered that the rudder was extremely difficult to move during the landing flare but nosewheel steering was enough to prevent a veer-off after touchdown. The aircraft was found to have a history of stiffness in rudder operation which a recent attempt to rectify had not resolved. The crew were aware of this and decided that despite a somewhat unsatisfactory pre-flight 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 un-drained moisture.
