## Discrepancy

(CAN) DURING AN ANNUAL INSPECTION  A FLAP EXTENSION ROD WAS FOUND CHAFED PART WAY THROUGH.THE DAMAGE WAS CAUSED BY A BEARING ON THE FORWARD FLAP BELLCRANK. THE SPHERICAL ROD END BEARING BECAME DISLODGED FROM THE BELLCRANK AND SHIFTED IN ITS COUNTERBORE ENOUGH TO CAUSE INTERFERENCE AT THE FIFTEEN DEGREE FLAP POSITION CHAFING THE FLAP EXTENSION ROD. A PILATUS REP WAS ON HAND AND ADVISED TO SECURE THE BEARINGS WITH LOCTITE COMPOUND.  AS A FOLLOW UP, THE BEARINGS WILL BE CHECKED ON A REGULAR BASIS TO DETERMINE THE INTEGRITY OF THE SYSTEM.
