## Discrepancy

(CAN) CREW NOTICED A LARGE AMOUNT OF OIL ON THE LT NACELLE WHICH APPEARED TO ORIGINATE FROM THE PROPELLER. THE ENGINE WAS SHUTDOWN DUE TO THE EXCESSIVE LEAKAGE AND THE AIRCRAFT RETURNED TO BASE.  THE PROPELLER NR 1 BLADE SEAL WAS REPLACED AND GROUND LEAK CHECKS CARRIED OUT.  THE SEAL (WHICH WAS FURTHER DAMAGED DURING REMOVAL) APPEARS TO HAVE HAD A TEAR ON THE SURFACE WHICH FACES OB AND IS EXPOSED WHEN INSTALLED. (TC NR 20070824006)
