## Discrepancy

NUMBER 1 ENGINE OIL LEAK IN FLIGHT.  QUANTITY DECREASED FROM 10.5 TO 3.5.  SMOKE IN TAILPIPE AND TURBINE AREA AFTER SHUTDOWN.  OIL LEAK CAUSED BY OIL LEAKING FROM NR 5 BEARING COMPARTMENT INTO HOT GASPATH AREA, GENERATING SMOKE AT ENGINE SHUTDOWN.  LEAK CAUSED BY EXCESSIVE OIL "COKING" DEPOSITS IN BEARING COMPARTMENT AREA.  OSV HAS REVIEWED AND CORRECTED PROCESS THAT ALLOWED THIS OVERSIGHT.
