## Discrepancy

DURING THE ANNUAL 375 HR INSP, ELEVATOR/EMPENNAGE INSP PANELS WERE REMOVED. RT ELEVATOR OTBD STABILIZER TO ELEVATOR HINGE FITTING WAS FOUND GROOVED ON TOP RADIUS OF THE FITTING.  INVESTIGATION REVEALED THAT THE SCREWS ATTACHING THE RT ELEVATOR END CAP FAIRING WERE TOO LONG FOR CLEARANCE BETWEEN THE THE FAIRING AND FITTING, CAUSING A .0625" GROOVE ON THE TOP OF THE FITTING.  SCREWS INSTALLED WERE NOT THE CORRECT SCREWS.  THE PARTS CATALOG CALLS FOR AN AN509-10-R7 SCREW.  HOWEVER, THIS SCREW APPEARS TO BE TOO LONG AS WELL.  INTEND TO INVESTIGATE USING A SHORTER SCREW IN THE AFFECTED AREA AND TO CHECK REST OF THE FLEET BEFORE THE REST OF THE ACFT ARE RETURNED TO SERVICE.   ALSO, ARE GOING TO PLACARD THE AFFECTED FAIRING AND HOLES TO ENSURE THAT THE SHORTER LENGTH SCREW IS USED.
