What was found
WHILE ON APPROACH, THE RT (LOW OIL PRESSURE) LIGHT ILLUMINATED. THE PILOT OBSERVED THE OIL PRESSURE INDICATOR WAS READING 40 PSI AND FALLING. THE DECISION WAS MADE TO SHUT THE RT ENGINE DOWN AS A PRECAUTION. THE FLIGHT CONTINUED AND AN UNEVENTFUL LANDING WAS MADE. UPON INVESTIGATION BY MAINTENANCE, IT WAS DETERMINED THAT THE GASKET AT THE NOSE CONE OF THE RT ENGINE HAD FAILED AND SEEPED OIL UNTIL THERE WAS AN INSUFFICIENT SUPPLY.
