## Discrepancy

AT SCHEDULED MAGNUFLUX INSPECTION, ENGINE TRUSS WAS DETERMINED TO HAVE A RADIAL CRACK IN THE LOWER RIGHT GUIDE PIN RADIUS.  RAYTHEON AIRCRAFT COMPANY, THE MANUFACTURER, DETERMINED THAT THE BOSS GUIDE WAS NOT REPAIRABLE AND THAT ITS REPLACEMENT WOULD REQUIRE USE OF THE PRODUCTION JIG.  NO REPAIR WAS AUTHORIZED.
