## Discrepancy

PDX - FLIGHT 2332 - AFTER TAKEOFF WITH THE GEAR UP AND THE FLAPS AT ZERO ON FLAP RETRACT (STILL MOVING), THE FIRST OFFICER WAS UNABLE TO TURN THE AIRCRAFT TO THE LEFT FOR ABOUT 4-5 SECONDS.  AFTER THE FLAPS WERE FULL UP CONTROL WAS RETURNED.  ON LANDING IN PDX, FLAPS 5 DEGREES, NO PROBLEMS.  AS THE LANDING GEAR WAS LOWERED, CONTROLS LOCKED AGAIN FOR 10-15 SECONDS.  AFTER GEAR WAS FULLY DOWN, CONTROL RETURNED.  IN BOTH CASES THE AUTOPILOT WAS OFF.  MAINTENANCE REPLACED THE AUTOPILOT ROLL SERVO AND CAPSTAN.  OPERATIONAL CHECKS GOOD.  AIRCRAFT RETURNED TO SERVICE.
