## Discrepancy

(CAN) DURING A ROUTINE INSPECTION, IT WAS NOTED THAT EXCESSIVE OIL WAS LEAKING AROUND THE MAGNETO GASKET. UPON REMOVAL OF THE MAGNETO, IT WAS NOTED THAT THE MAGNETO HAD ABNORMAL AMOUNT OF WEAR IN THE MAGNETO CLAMP AREA. FURTHER INVESTIGATION REVEALED ONE OF THE HOLD DOWN CLAMPS WAS GROUND AWAY IN THE FACE CONTACT AREA, RESULTING IN THE MAGNETO HANGING ON THE CASE BY ONE CLAMP. BOTH THE MAGNETO AND CLAMPS WERE REMOVED AND SENT TO THE OVERHAUL FACILITY FOR REPLACEMENT.
