## Discrepancy

CLT - BEFORE DEPARTURE FROM EWR, FLIGHT CONTROL CHECKED GOOD ON GROUND.  AFTER DEPARTURE, AIRCRAFT EXPERIENCED A RIGHT TURN ON TAKEOFF AND RIGHT ROLL CORRECTION ON APPROACH.

ADJUSTED LEFT AND RIGHT AILERONS PER MM 27-11-00-825.  ALSO, REMOVED AND REPLACED FEEL AND CENTERING UNIT CAM BEARING PER OHM 27-14-21. TEST OP GOOD.  AIRCRAFT OK FOR SERVICE.
