## Discrepancy

(CAN) DURING CRUISE, CREW NOTICED OIL PRESSURE DROPPING AND ELECTED TO SHUTDOWN THE LT ENGINE AS A PRECAUTION. THE FLIGHT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT. THE AGB WAS REMOVED TO INVESTIGATE OIL LOSS THRU THE OVERBOARD VENT AND THE STARTER GENERATOR SPLINE, CARBON SEAL WAS FOUND CRACKED ALLOWING OIL TO VENT. SIX QUARTS WERE DISPLACED CAUSING THE OIL PRESSURE DROP.
