## Discrepancy

FLT NUMBER: DVR023, ENGINE FAILURE AND EMERGENCY LANDING.  SHORTLY AFTER DEPARTURE FROM BON, THE CREW EXPERIENCED A LOSS OF FUEL PRESSURE AND OBSERVED A DECREASING OIL PRESSURE ON THE LEFT-HAND (LH) ENGINE. DUE TO THESE CRITICAL INDICATIONS, A PRECAUTIONARY SHUTDOWN WAS PERFORMED AND A MAYDAY CALL WAS ISSUED. THE AIRCRAFT RETURNED TO BON FOR AN EMERGENCY LANDING AND THE AFFECTED LH ENGINE WAS FEATHERED PRIOR TO LANDING.  THE LH ENGINE WAS DECLARED UNSERVICEABLE (U/S) AND SUBSEQUENTLY REPLACED.  A DUPLICATE INSPECTION, INCLUDING A RETURN TO SERVICE INSPECTION (RII), WAS PERFORMED ON THE REPLACEMENT ENGINE.  A MALFUNCTION DEFECT REPORT (MDR) WAS SUBMITTED ACCORDING TO CCAR 5.4.1.5,  3 DAYS AFTER THE INCIDENT.  THE CURACAO CIVIL AVIATION AUTHORITY (CCAA) IS CURRENTLY AWAITING A TEARDOWN REPORT FOLLOWING THE OVERHAUL OF THE AFFECTED ENGINE, WHICH WILL BE SENT TO THE OVERHAUL FACILITY. LYCOMING WILL BE NOTIFIED OF THE INCIDENT FOR FURTHER INVESTIGATION AND FOLLOW-UP.
