## Discrepancy

HAVE RECEIVED AN ENGINE THAT HAS SUFFERED AN INFLIGHT FAILURE AND SHUTDOWN.  UPON INITIAL INVESTIGATION WE HAVE IDENTIFIED THAT A 1ST STAGE TURBINE WHEEL BLADE APPEARS TO HAVE FAILED IN THE ROOT AREA.  THIS BLADE HAS CAUSED SUBSTANTIAL DAMAGE TO THE REMAINDER OF THE 1ST STAGE WHEEL AND ALL COMPONENTS DOWNSTREAT OF IT.  THE ENGINE WAS LAST IN OUT SHOP ON 15TH MAY, 2006 WHEN A CAM INSP WAS PERFORMED AT 8894.3 TSN, 10114 CSN.  THE SUSPECT 1ST STAGE WHEEL WAS REPLACED AT THAT TIME WITH AN OVERHAULED ITEM FROM MFG WHICH HAD NEW BLADES.  (K)
