## Discrepancy

AIRCRAFT DIVERTED TO MCI DUE TO RIGHT ENGINE OIL LOSS.  AN IN-FLIGHT SHUT DOWN OCCURRED.  THE CARBON SEAL RETAINER SPUN AND DISENGAGED THE CARBON SEAL ELEMENT FROM THE SEAL FACE.  THE SEAL LOSS RESULTED IN ENGINE OIL BEING DISCHARGED OUT OF THE BREATHER DUCT.  THE MAIN GEARBOX ASSEMBLY WAS REPLACED.  OPERATIONS CHECK NORMAL.
