## Discrepancy

ENGINE 1537 (FROM 525-0264) WAS RETURNED TO THE REPAIR STATION FOR BROKEN IP BLADES AFTER THE CUSTOMER REPORTED VIBRATIONS, HIGHER ITT & FUEL FLOW, AND A SMALL ABNORMAL NOISE.  UPON DISASSEMBLY, VISUAL INSPECTION AND FPI REVEALED THAT 2 BLADES WERE LIBERATED AND 3 BLADES WERE CRACKED AT THE ROOT.  THE IP STATOR IS RUBBED, AND THE FAN ROTOR HAS SOME GROOVING ON THE TIPS OF 3 ADJACENT BLADES FROM CONTACTING THE FAN CASE INSERT RIBS.
