## Discrepancy

THIS PLANE HAS CONTINUED REPETITIVE CORROSION OF THE ALUMINUM PARTS OF THE ELEVATOR.  IT IS SEEN AT EMANATING FROM THE BONDED PARTS WHERE THE PIECES ARE RIVETED TOGETHER.  IT WAS REPAINTED ONCE WHEN THE AIRFRAME WAS ONLY 2 YEARS OLD.  IT THEN AGAIN OCCURRED NEXT YEAR.  I BELIEVE THIS IS A DEFECT WITH THE PRIMING WHEN THE PARTS WHERE ORIGINALLY PUT TOGETHER AND IS A PREP ISSUE IN THIS VINTAGE.  I HAVE SPOKE TO MANY 2022 OWNERS FACING THE SAME PROBLEM AND MANY HAVE SHOWN ME BORE SCOPES OF THE INSIDE WHICH SHOW A LOT OF CORROSION WHICH MAKES ME CONCERNED ABOUT A STRUCTURE FAILURE INTERNALLY.
