## Discrepancy

ENGINE WAS SQUAWKED FOR A 41 DEG C, ITT SPLIT.  DURING, ON WING, TROUBLESHOOTING, DAMAGE WAS NOTED ON A 2ND STAGE IP ROTOR BLADE.  THE ENGINE WAS REMOVED FOR FURTHER INVESTIGATION.  DISASSEMBLY REVEALED 2 LIBERATED 2ND STAGE BLADES ON THE IP ROTOR, PN 119345, SN HW34114 AT THE ROOT RADIUS.  VISUALLY THERE WERE SEVERAL OTHER SECOND STAGE BLADES WITH CRACK INDICATIONS STEMMING FROM THE T/E AT THE ROOT RADIUS.  THE BLADE FRAGMENTS WERE INGESTED INTO THE CORE CAUSING SECONDARY DAMAGE TO THE IP STATORS AND HPC ROTOR.
