## Discrepancy

(CAN) DURING DESCENT, THE AP SEEMED TO BE HAVING PROBLEMS STAYING ON COURSE,  THE AUTOPILOT WAS DISCONNECTED AND ROLL CONTROL APPEARED TO BE SOMEWHAT, JAMMED, BUT COULD STILL CONTROL ACFT WITH AVAILABLE ROLL CONTROL.  IT WAS JUST A REALLY, STIFF,  CONDITION THAT LASTED FOR A MINUTE OR 2.  MAINTENANCE REPLACED THE AP ROLL SERVO.
