Flight Crew Returned To Departure Airport
Aircraft
We started the engines and taxied to Runway 33L and completed all taxi checks including the rudder bias with no abnormalities noticed. During takeoff roll extra right rudder pressure was required. At the time I thought the winds may have shifted a little and the plane was trying to weathervane. During the initial climb I continued to apply more right rudder and dialed in all the right rudder trim available. The aircraft still did not maintain coordinated flight. The decision was made at that time to return to the departure airport. We asked ATC for vectors to a visual on 33L and landed without incident. The plane landed; taxied and turned on the ground with normal rudder pressures.
A CE560 Captain added right rudder during takeoff thinking a crosswind was the cause but discovered after takeoff that rudder was needed continuously and so returned to the departure airport.
