What was found
DURING A RECENT SCHEDULED INSPECTION, CRACKS WERE FOUND IN THE SUPPORT DOUBLER EMANATING ACROSS THE LOWER LT MOUNT BOLT HOLE OF THE AFT ELEVATOR BELLCRANK MOUNT. ALSO SEVERAL ADJACENT RIVETS IN THIS DOUBLER WERE ALSO CRACKED ACROSS THEIR HOLES AND THE DOUBLER WAS DISTORTED. IT WAS DISCOVERED THAT THE 2 SUPPORT ANGLE BRACKETS FOR THE AFT ELEVATOR MOUNT BRACKET WERE NOT INSTALLED, WHICH ALLOWED THE DOUBLER TO FLEX. HC
