Aircraft; Procedure
RUD TRIM 1 Failure inflight. Felt several uncommon yaw inputs followed by a right rudder trim input of 3.5 that held the aircraft in a slip at FL340. [Advised ATC] and we diverted from the intended destination to ZZZ for the longer runway.Maintenance kept signing off all the tale tell signs that this was happening. It appears ours was more severe and the only one where the aircraft was held in a yaw.
A321 Captain reported experiencing a rudder trim failure in flight requiring a divert to a suitable airport.
