## Discrepancy

IAW REMOTE DIAGNOSTIC SYSTEM, THE RT ENGINE HAD A SHARP DECREASE IN TAKEOFF, EGT MARGIN AND CORE SPEED AS WELL AS IN INCREASE IN EGT AND FUEL FLOW.  MAINTENANCE PERSONNEL PERFORMED THE RT BORESCOPE INSPECTION OF THE HIGH PRESSURE TURBINE AND COMBUSTION SECTION IAW AMM 72-00-00, DETECTING MISSING MATERIAL, SEVERAL CRACKS, NICKS AND DENTS ON BLADES AND MULTIPLE CRACKS, BURN HOLES AND MISSING MATERIAL ON COMBUSTION SECTION OUT OF LIMITS; SO THE RT ENGINE WAS REPLACED IAW AMM 71-00-02 AND OPS TEST WAS PERFORMED IAW AMM 71-00-00, TESTED CORRECT.
