## Discrepancy

(CAN) IN CRUISE, THE ENGINE EXHIBITED VERY LOW ITT AND OIL PRESSURE. THIS WAS FOLLOWED BY A FIRE WARNING ANNUNCIATION AND THE CREW SHUT THE ENGINE DOWN IN FLIGHT AND DIVERTED TO POINT OF DEPARTURE.  SUBSEQUENT INSPECTION REVEALED A FRACTURED 6&7 BEARING OIL SCAVENGE TUBE, FRACTURED POWER TURBINE BLADES, EXTERNAL OIL LEAKAGE AND EVIDENCE OF AN EXTERNAL FIRE.  P&WC WILL INVESTIGATE THE EVENT AND ADVISE O F ROOT CAUSE ONCE DEFINED.
