## Discrepancy

(CAN) A/C DEPARTED. DURING CLIMB OUT THROUGH FL250, FLT CREW HEARD ABNORMAL SOUND FROM REAR OF A/C.  ALL ENGINE PARAMETERS WERE NORMAL EXCEPT FOR RISE IN EGT.  FLT CREW REQUESTED TO RETURN.  APPROXIMATELY 30 NAUTICAL MILES FROM LANDING,  ENGINE BEGAN TO MAKE ABNORMAL SOUNDS, SECURED  ENGINE.  A/C LANDED SUCCESSFULLY.   CONTRACTED AMO AND ADVISED OF CONDITION OF ENGINE AS DAMAGE TO REAR FAN AREA & EXCESSIVE OIL LEAK. BY REMOVING ENGINE TAIL CONE, IT HAS BEEN OBSERVED THAT AFT OIL PRESSURE LINE TO AFT FAN BEARING NR 5 FOUND CRACKED.  ALTHOUGH SERVICE DIFFICULTY REPORT IDENTIFIES CRACKED TUBE ASSY P/N 5002T27P01, WE SHOULD NOT DISREGARD POSSIBILITY OF BEARING FAILURE.
