What was found
DURING AN ANNUAL INSPECTION, WHILE MEASURING RUDDER TRAVELS IT WAS FOUND THAT IF A LITTLE EXTRA PRESSURE WAS APPLIED TO THE RUDDER TRAILING EDGE, ONCE IT HAD REACHED ITS STOP, THE RUDDER TRAVELED AN EXTRA INCH PAST THE SPECIFIED TRAVELS. WHILE THE STOP REMAINED STATIONARY UPON INSPECTION, IT WAS FOUND THAT ALL THE RIVETS ON THE TOP AND BOTTOM OF THE RUDDER TORQUE TUBE WERE LOOSE AND WORN. THE CAUSE IS MORE THAN LIKELY FROM WIND DAMAGE. RECOMMENDATIONS: MAKE SURE THAT THE RUDDER GUST LOCK IS INSTALLED AFTER A FLIGHT.
