## Discrepancy

(CAN) LOSS OF OIL PRESSURE DURING INITIAL CLIMB, THE CREW NOTICED THE LT ENGINE OIL PRESSURE WARNING LIGHT FLICKERING. AND THEN THE ENGINE OIL PRESSURE BEGAN TO DROP.  THE CREW DECLARED AN EMERGENCY, PERFORMED A CAUTIONARY ENGINE SHUTDOWN, AND RETURNED TO DEPARTURE, WHERE THE ACFT LANDED SAFELY.  INVESTIGATION REVEALED THAT THE OIL FILLER CAP HAD NOT BEEN FULLY SECURED CAUSING THE LOSS OF APPROX 6 LITERS OF OIL. MFG WILL INVESTIGATE TO ESTABLISH ROOT CAUSE AND SUPPLEMENT THE REPORT ONCE THE INFORMATION IS AVAILABLE. (TC 20100209004)
