## Discrepancy

ENGINE LOST POWER IN FLIGHT.  UPON INSPECTION OF THE TURBINE, THE 2ND STAGE TURBINE WHEEL WAS FOUND TO HAVE 1 BLADE MISSING WHICH SUBSEQUENTLY CAUSED SIGNIFICANT FOD DAMAGE TO THE 2ND, 3RD AND 4TH STAGE NOZZLES AND THE 3RD AND 4TH STAGE STAGE WHEELS AS WELL AS OTHER TURBINE SECTION DISTRESS.  ALL DAMAGE WAS CONTAINED WITHIN THE TURBINE.  THE 1ST AND 2ND STAGE WHEELS AND NOZZLES HAVE BEEN SENT TO MFG FOR INVESTIGATION.
