DURING DESCENT FOR THE LANDING APPROACH THE PILOT EXPERIENCED UNCOMMANDED ROLL DIVERGENCE. THE AIRCRAFT WAS AT APPROXIMATELY 240 KNOTS, CLEAN CONDITION, AND POWER WAS REDUCED AT THE TIME OF THE OCCURRENCE. THE AIRCRAFT WAS FOLLOWING AN MD-80 WHEN THE EVENT OCCURRED. THE FIRST PILOT WAS AT THE CONTROLS WHEN THE UNCOMMANDED ROLLS OCCURRED, HOWEVER, THE CAPTAIN ASSUMED CONTROL EARLY DURING THE SEQUENCE. IT WAS NOTED THAT THE AUTOPILOT ALTITUDE HOLD WAS ENGAGED. THE INITIAL DIVERGENCE WAS A 20 DEGREE RIGHT ROLL. AS THE RIGHT ROLL WAS DEVELOPING THE PILOT APPLIED A LEFT CORRECTION, AND THE AIRCRAFT ROLLED 30 DEGREES LEFT. THE PILOT THEN APPLIED RIGHT RUDDER WHICH RESULTED IN THE WINGS COMING TO THE LEVEL ATTITUDE. AN EXAMINATION OF THE FLIGHT CONTROL SYSTEM FAILED TO REVEAL ANY ANOMALIES.
