## Discrepancy

BORESCOPE INSPECTION FOUND EVIDENCE OF COATING LOSS FROM COMPRESSOR TURBINE BLADES.  COATING WAS ERODED FROM LEADING EDGES OF SOME BLADES.  ENGINE WAS SPLIT AT 'C' FLANGE, HOT SECTION INSPECTED FURTHER.  CT WHEEL REMOVED AND SHIPPED TO PRATT AND WHITNEY FOR INSPECTION AND DETERMINATION OF CAUSE FOR COATING LOSS.  CT BLADES WERE INSTALLED AT OVERHAUL IN SERVICEABLE CONDITION.  THESE BLADES WILL NOT BE REINSTALLED IN THIS ENGINE.
