What was found
(CAN) DURING MID-LIFE STRUCTURAL INSPECTION THE ABOVE CLEAT WAS FOUND TO BE EXFOLIATED IN VARIOUS SPOTS BETWEEN THE WEBS. IT IS LIKELY THAT STANDING WATER COULD SIT IN THE WEB AREAS AND SPEED UP THE CORROSION PROCESS. THE VERTICAL STAB WAS REMOVED TO OBTAIN ACCESS TO THE CLEAT. THE CLEAT WAS REPLACED AND THE VERTICAL STAB REINSTALLED.
