## Discrepancy

IN-FLIGHT SHUTDOWN OF THE NR 2 ENGINE DUE TO LOW OIL PRESSURE CAUTION LIGHT, OIL PRESSURE INDICATION WAS NORMAL.  PILOTS INITIATED CHECKLIST AND PERFORMED SHUTDOWN AND RETURNED TO BASE.  ENGINE IS A MODIFIED CIS ENGINE.  THE PROBLEM WAS FOUND TO BE A DEFECTIVE LOW OIL PRESSURE SWITCH.  THE OIL WAS A NORMAL COLOR AND PROPER QUANTITY, THE FILTERS WERE CLEAR.  LOW OIL PRESSURE SWITCH REPLACED, SYSTEMS CHECKED, A/C RETURNED TO SERVICE.
