## Discrepancy

DURING OUR TRAINING FLIGHT WE NOTICED THE R OIL PRESSURE ANNUNCIATOR FLICKERING. THE RIGHT OIL PRESSURE GAUGE CONFIRMED LOW OIL PRESSURE WITH A READING HOVERING AROUND 40 PSI.  EVERY OTHER ENGINE INSTRUMENT WERE IN NORMAL PARAMETERS.  PER THE CHECKLIST, WE PERFORMED A PRECAUTIONARY ENGINE SHUTDOWN.  RIGHT ENGINE FEATHERED NORMALLY.  WE PROCEEDED TO DIVERT TO KGYI AND DECLARED AN EMERGENCY WHERE A NONEVENTFUL LANDING WAS PERFORMED.   UPON INITIAL INSPECTION WE FOUND A LOOSE OIL LINE ON THE RGB THAT WE TIGHTENED.  REQUIRED TO REPLACE THE PRIMARY GOVERNOR DUE TO A DROP IN OIL PRESSURE BECAUSE OF A OIL LEAK. COMPLIED WITH INSPECTION PROCEDURE IN MM 72.00.00 PARA R1. ALL WORK DONE IAW BCKA AND MM 79.20.02, 79.30.05, 72.00.00, 61.20.00 AND 20.06.00. NO FURTHER DISCREPANCIES AT THIS TIME.
