## Discrepancy

ENGINE WAS REPORTED TO HAVE FLAMES OUT OF TAILPIPE.  TEARDOWN OF ENGINE SHOWS THAT A TURBINE BLADE HAD SEPARATED AT THE FIRTREE.  BLADE DEBRIS CAUSED DAMAGE TO TURBINE OIL LINE, RESULTING IN A LEAK.  TURBINE DISC WAS REBLADED AT LAST MAINTENANCE EVENT.  TURBINE DISC/BLADES WERE PROVIDED TO MFG PROJECT ENGINEERING FOR MATERIAL ANALYSIS.  (K)
