## Discrepancy

1.5 HOURS INTO THE FLIGHT, THE THROTTLE WAS RETARDED, IMMEDIATELY OIL SPRAYED ONTO THE WINDSCREEN.  UPON DESCENT THE OIL DID NOT CONTINUE TO SPRAY ON THE WINDSCREEN. AN EMER WAS DECLARED & THE ACFT LANDED WITHOUT INCIDENT.  A NEW PROP SHAFT SEAL THAT HAD JUST BEEN INSTALLED HAD FAILED.  THE SEAL WAS GALLED & HAD FUSED TO THE PROP SHAFT.
