## Discrepancy

AIRCRAFT HAS BAD VIBRATION THROUGH YOKE & RUDDER PEDALS.  VIBRATION GETS MUCH WORSE WITH INCREASE IN AIRSPEED.  POWER SETTINGS MODE MADE NO DIFFERENCE.  TROUBLE SHOT THE DISCREPANCY TO A DEFECTIVE RUDDER LOWER TRIM TAB HINGE PIN THAT BACKED OUT CAUSING THE VIBRATION IN FLIGHT.  RUDDER ASSEMBLY WAS REPLACED DUE TO DAMAGE CAUSED TO HINGE FROM VIBRATION.  A SUCCESSFUL OPERATIONAL CHECK FLIGHT WAS PERFORMED.  ACFT WAS RETURNED TO SERVICE.
