## Discrepancy

WHILE EN ROUTE TO YIPSILANTI, THE RT OIL PRESSURE WAS DECREASING FOLLOWED BY RT GENERATOR FAILURE.  A PRECAUTIONARY ENGINE SHUT DOWN WAS MADE AND AIRCRAFT DIVERTED TO ANOTHER AIRPORT WHERE AN UNEVENTFUL LANDING WAS MADE.  OIL LEVEL WAS FOUND TO BE LOW DUE TO A DAMAGED OIL SEAL.  THIS OIL SOAKED THE GENERATOR.  OIL SEAL AND GENERATOR WERE REPLACED, LEAK CHECKED, AND FUNCTIONALLY TESTED.  OIL FILTER AND SUMP PLUG WERE INSPECTED, NO DAMAGE NOTED.
