What was found

(CAN) DURING ROUTINE INSPECTION THE RUDDER HORN ASSY AT THE AREA WERE THE HORN STRIKES THE RUDDER STOPS HAD BEEN DAMAGED. WE BELIEVE BY GUSTY WINDS WITHOUT THE RUDDER LOCK ON. THE RUDDER STOP SCREW HAD ACTUALLY ROLLED THE ALUMINIUM BACK ON THE HORN WHICH MADE FOR A HAZARDOUS SITUATION DUE TO THE FACT THAT THE STOP SCREW COULD HAVE JAMED OVER THE ROLLED ALUM.THE RUDDER HORN AND RIB ASSY. HAVE BEEN REPLACED WITH NEW UNITS. NO DAMAGE WAS FOUNDS IN THE STOP ATTACHEMENT AREA.
