## Discrepancy

(CAN) THIS MORNING THE PILOT WAS IN CRUISE WHEN A LOUD BANG OCCURRED AND THE TOT INCREASED.   WITH NO ENGINE, THE PILOT AUTOROTATED TO A CLEAR SPOT TO THE GROUND.  NO DAMAGE TO AIRCRAFT.  THE ENGINE HAD FAILED.  A VISUAL OF THE TURBINE SECTION SHOWS SUBSTANTIAL DAMAGE.  AT THIS TIME UNKNOWN SOURCE OF WHAT CAUSED THIS DAMAGE.
