What was found
DURING A RECENT INSPECTION IT WAS NOTED THAT ALL OF THE LOCK FASTENERS THAT SECURE THE STEEL ATTACH FITTINGS TO THE AIRFRAME FOR THE ENGINE MOUNT LOWER ATTACH POINTS WERE VERY LOOSE (COULD BE TURNED BY HAND). ACCESS TO THE AREA MAKES IT DIFFICULT TO INSPECT. PROBLEM WAS CORRECTED BY INSTALLING THE NEXT SIZE UP LOCK FASTENERS.
