## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

NARRATIVE: AFTER DEPARTURE FROM MARLBORO AIRPORT, MARLBORO, NJ UNDER VISUAL METEOROLOGICAL CONDITION (VMC), THE PILOT EXPERIENCED A LOSS OF ENGINE POWER AND OIL PRESSURE. UPON INITIATING A TURN BACK TO THE AIRFIELD, THE ENGINE ABRUPTLY STOPPED AND A FORCED LANDING WAS EXECUTED ON TO STATE HIGHWAY 18 SOUTH AND THE AIRCRAFT CAME TO A STOP ON THE GRASSY MEDIAN WITHOUT INCIDENT. UPON INVESTIGATION, IT WAS DETERMINED THAT THE AIRCRAFT'S VACUUM PUMP WAS PREVIOIUSLY REMOVED BY A CERTIFICATED MECHANIC FOR REPAIR AND HE FAILED TO INSTALL A COVER PLATE AND GASKET ON THE ENGINE'S VACUUM PUMP DRIVE PAD ADAPTOR. WITH THE ABSENCE OF THE PUMP AND THE FAILURE TO INSTALL THE COVER PLATE AND GASKET IN ITS PLACE, CAUSED THE ENGINE TO DISSIPATE OIL FROM A PORT ON THE PAD ADAPTOR (DESIGNED FOR A WET PUMP INSTALLATION) AND SUBSEQUENT ENGINE SEIZURE. ^PRIVACY DATA OMITTED^ THIS INCIDENT INVESTIGATION IS CONSIDERED CLOSED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
