## Discrepancy

(CAN) UPON PILOT GETTING TO ACFT TO PERFORM A PREFLIGHT WALK AROUND CHECKS, IT WAS NOTICED THAT THE TURN COORDINATOR WAS NOT CENTERED HORIZONTALLY, ACT WAS MOVED TO LEVEL GROUND TO MAKE SURE THAT IT WAS NOT THE GROUND SURFACE ANGLE.  AFTER CHECKS IT WAS FOUND TO BE THE TURN COORDINATOR ITSELF, TURN COORDINATOR R & R WITH SERVICEABLE UNIT, REPLACED UNIT CHECKED SERVICEABLE UPON FUNCTION CHECK.
