## Discrepancy

INDIA-BASED SERVICE CENTER (AIRWORKS INDIA ENGINEERING PVT) ENGINEER CONTACTED WILLIAMS INTERNATIONAL (W.I.) OEM PRODUCT SUPPORT TO REPORT A POST-FLIGHT FINDING OF AN OIL LEAK IN THE HOT-SECTION AREA OF THE ENGINE.  THE OBSERVED OIL LEVEL IN THE ENGINE SIGHT-GLASS WAS ALSO REPORTED TO BE LOW.  W.I. PRODUCT SUPPORT RECOMMENDED A BORESCOPE INSPECTION OF THE ENGINE AND THE INDIA SERVICE CENTER TECHNICIANS SUBSEQUENTLY COMPLETED THE INSPECTION, WHICH REPORTEDLY REVEALED A LIBERATED PIECE OF ONE HIGH PRESSURE TURBINE (HPT) BLADE.  W.I. PRODUCT SUPPORT THEN DIRECTED REMOVAL OF THE ENGINE FOR SHIPMENT TO OUR REPAIR STATION FOR DISASSEMBLY, INSPECTION, AND CONFIRMATION OF THE BORESCOPE FINDINGS.  AFTER INDUCTION INTO OUR REPAIR STATION, DISASSEMBLY AND INSPECTION CONFIRMED ONE LIBERATED HPT BLADE WITH EVIDENCE OF SECONDARY DAMAGE TO ADJACENT HPT BLADES.  THE LIBERATED PORTION OF THE HPT BLADE APPEARS TO HAVE DAMAGED AN OIL LINE WITHIN THE HOT-SECTION OF THE ENGINE, RESULTING IN THE ELEVATED OIL CONSUMPTION AND EVIDENCE OF OIL LEAK IN THE HOT SECTION OBSERVED BY THE AIRWORKS INDIA ENGINEER.
