## Discrepancy

DURING A SHOP OVERHAUL MAGNETIC PARTICLE INSPECTION, THE FORWARD ENGINE MOUNT CONEBOLT WAS FOUND TO HAVE SEVERAL DEFECTS IN ONE END FACE.  BOTH THE BOLT (P/N R18210-2T, S/N 15BR124) AND ITS ASSOCIATED ENGINE MOUNT (P/N K2219) ARE MANUFACTURED BY BARRY CONTROLS.  THE SUBJECT BOLT WAS ROCKWELL HARDNESS TESTED BY NWA AT 37.5 PRIOR TO SHIPMENT BACK TO BARRY CONTROLS FOR FURTHER ANALYSIS.
