## Discrepancy

WILLIAMS INTERNATIONAL PRODUCT SUPPORT ADVISED THE REPAIR STATION THAT THE CUSTOMER HAD REPORTED BEING TEMPERATURE LIMITED DURING TAKEOFF CONDITIONS.  A SERVICE CENTER PERFORMED A BORESCOPE INSPECTION AND FOUND DAMAGE TO THE HPC ROTOR AND HPC COVER.  W.I. PRODUCT SUPPORT DIRECTED THE SERVICE CENTER TO REMOVE THE ENGINE AND RETURN IT TO OUR REPAIR STATION FOR DISASSEMBLY AND INVESTIGATION.  THE REPAIR STATION COMPLETED DISASSEMBLY OF THE ENGINE AND DISCOVERED THE INTERMEDIATE PRESSURE COMPRESSOR ROTOR HAD A LIBERATED 3RD STAGE BLADE.
