## Discrepancy

DURING ROUTINE INSPECTION, A THRU-BOLT NUT, TWELVE POINT PN 65254, WAS FOUND FRACTURED & LAYING IN THE BOTTOM OF THE ENG COWLING.  THERE WERE NO SIGNS OF CORROSION ON THE NUT.  THE ENG WAS REMOVED TO BE DISASSEMBLED, INSPECTED & OVERHAULED.  THE NUT WAS RETURNED TO THE ENG MFG FOR FURTHER EXAMINATION.
