## Discrepancy

INCOMING INSPECTION FOUND AILERON DRIVE YOKE ATTACH CASTING BENT.  UPON FURTHER INSPECTION IT WAS DISCOVERED THE DRIVE YOKE UPPER OR LOWER SHIMS WERE NOT INSTALLED.  DRIVE YOKE ATTACH BOLT WAS INSTALLED CAUSING THE CASTING TO BE BENT AND REQUIRES REPLACEMENT BY OEM.  THIS COULD HAVE BEEN PREVENTED BY FOLLOWING MAINTENANCE MANUAL INSTALLATION INSTRUCTIONS.  (K)
