## Discrepancy

DURING PRE-FLIGHT CHECK, PILOT COMPLAINED THAT THE TAIL ROTOR PEDALS WERE STIFF.  MECHANIC CONFIRMED THIS AND DETERMINED THAT THE TAIL ROTOR HUB ASSEMBLY NEEDED TO BE DISSASEMBLED FOR FURTHER INVESTIGATION. UPON DISSASEMBLY MECHANIC FOUND TEFLON FRICTION WASHER HAD BECOME UNBONDED FROM TAIL ROTOR HUB BUSHING THIS WAS CREATING THE HUB TO BIND DURING PEDAL TRAVEL. THE BUSHING AND FRICTION WASHER ARE PART OF A ASSY (PN 109-8131-36-101).
