## Discrepancy

(CAN) DURING OPS CHECKS OF THE ENGINE AFTER ENGINE INSPECTION, IT WAS NOTED THAT THE FRONT ENGINE LT MAG HAD A DROP OF 250.  THE MAGNETO WAS REMOVED AND DISASSEMBLED FOR INSPECTION.  IT WAS THEN NOTICED THAT THE CLAMPS THAT BOTH OF THE CLAMPS THAT HOLD DOWN THE COIL, PN 10-50765, HAD BROKEN OFF.  THE LOOSE PIECES INSIDE THE MAGNETO CAUSED DAMAGE TO THE HOUSING AND DISTRIBUTOR GEAR.
