## Discrepancy

FLIGHT DIVERTED DUE TO NR 1 ENGINE OIL LEAK.  NUMBER 5 BEARING CARBON SEAL HOUSING WAS FOUND TO BE OUT OF DIMENSION, DEFLECTED, AND SCORED.  IT PERMITTED AN OIL PATH TO EXIST AT THE HOUSING/TURBINE EXHAUST CASE(TEC) ATTACHMENT FLANGE.  ONCE PAST THE FLANGE OIL MADE ITS WAY INTO THE GASPATH.  OIL DID NOT GET BY THE CARBON SEAL BECAUSE NO COKING/STREAKING WAS EVIDENT ON THE ID OF THE T6 INNER ROTATING AIRSEAL.
