## Discrepancy

DURING A ROUTINE SCHEDULED PRISM INSPECTION OF THE LEFT PILOTS WINDSHIELD, A DEFECT WAS NOTED IN THE DEFOG NOZZLE AREA.  THE DEFOG NOZZLE ASSY WAS REMOVED AND FURTHER EXAMINATION REVEALED A 2.8 INCH L  BY .8 INCH W V-GROOVE WITH A VARYING DEPTH OF LESS THAN 4" LOCATED ON THE OUTER STRUCTURAL LAYER.  NO OTHER DEFECTS WERE NOTED IN THE WINDSHIELD ASSY, DEFOG NOZZLE, OR RELATED PLUMBING OR SEALS.  THE WINDSHIELD ASSY WAS REPLACED WITH A NEW UNIT OF SAME PART NUMBER.
