## Discrepancy

(CAN) UNCONTAINED EVENT SHORTLY AFTER DEPARTURE, THE PILOT NOTED THAT THE LT ENGINE TORQUE WAS FLUCTUATING, WHICH WAS FOLLOWED BY A LOUD NOISE AND FLAMES FROM THE EXHAUST.  THE ENGINE WAS SHUTDOWN AND A UNEVENTFUL SINGLE ENGINE LANDING WAS MADE AT THE DEPARTURE AIRPORT.  GROUND INSP REVEALED THAT ALL POWER TURBINE BLADES HAD FRACTURED AND DEBRIS HAD EXITED THE GAS GENERATOR CASE AND WERE FOUND IN THE LOWER COWL.  NO AIRFRAME DAMAGE WAS REPORTED.  THE ENGINE WILL BE FORWARDED TO MFG FOR INVESTIGATION UNDER THE SUPERVISION OF THE AUTHORITIES.  MFG WILL INVESTIGATE TO ESTABLISH ROOT CAUSE AND SUPPLEMENT THE REPORT ONCE THE INFORMATION IS AVAILABLE.
