## Narrative

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

DURING FLIGHT LEFT ENGINE SHUT DOWN DUE LOW OIL QUANTITY

IN VICINITY OF ORD, DECLARED PAN PAN AND REQUESTED DIVERSION TO ORD. FIRETRUCKS FOLLOWED AIRCRAFT DOWN RUNWAY, NOTHING TO NOTE FROM EMERGENCY CREWS, TAXIED TO GATE AND DEPLANED NORMAL

MAINTENANCE EVALUATION, LH ENGINE IFSD DUE TO LOW OIL QUANTITY AND LOW OIL PRESSURE WARNING. DURING LEAK ISOLATION MAINTENANCE FOUND OIL LEAK FROM UNION ON FUEL OIL COOLER.  AFTER CLOSER INSPECTION THE O-RING IS PROTRUDING, AND UNION DOESN'T APPEAR TO BE FLUSH TO FOC. DEFECT L625930 WAS CREATED. AIRCRAFT REMAINS ON THE GROUND IN ORD AND IT’S EXPECTED THAT AN ENGINE IS REQUIRED

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.
