## Discrepancy

THE NR 2 ENGINE FIRST STAGE TURBINE NOZZLE SHIELD WAS FOUND TO HAVE AN .8750 INCH BY 1.75 INCH SECTION MISSING AT THE 6 O'CLOCK POSITION.  THIS DEFECT WAS FOUND DURING A ROUTINE INSPECTION.  IT WAS SEEN  THROUGH THE FUEL NOZZLE MOUNTING HOLE.  AFTER REMOVAL OF PART, ALLISON CEB 72-3208 WAS PERFORMED ON THE PART.  THE NOZZLE SHIELD PASSED THE TEST WHICH IS USED TO DETERMINE IF THE NOZZLE WAS MADE OF THE PROPER MATERIAL.
