## Discrepancy

DURING A SCHEDULED 4200 HR O/H THE ABOVE DESCRIBED CARRIER WAS FOUND TO HAVE 3 CRACKS AT 3 SEPARATE LOCATIONS IN THE CARRIER TO COUPLING MOUNTING HOLE LOCATIONS.  THESE CRACKS WERE DETECTED DURING FLUORESCENT PENETRANT INSPECTION.  FOR THE FUTURE A MIDLIFE INSPECTION MAY BE AN OPTION TO DETECT THESE CRACKS, AS THIS AREA HAS BEEN PRONE TO CRACKS IN THE PAST.
