## Discrepancy

(CAN) AFTER LANDING, OIL WAS FOUND ALL OVER TAIL GEARBOX AREA, MAINTENANCE WAS CALLED AND T/R G/B WAS REPLACED WITH A RENTAL AND NO FURTHER PROBLEM WAS FOUND.  UPON INSPECTION AT MAIN BASE THE VENT HOLE ON THE INPUT WAS FOUND PLUGGED UP , THIS WE FEEL WAS THE CAUSE OF THE MAG SEAL TO BECOME DISLODGED AND BEGIN LEAKING.  THIS GEARBOX WAS CLOSE TO O/H SO IT WAS SENT IN EARLY AND NEW SEAL WAS INSTALLED.
