## Discrepancy

ACFT PERFORMED AN UNSCHEDULED LANDING, DUE TO DURING CLIMB THE ENG OIL FILTER SENSOR AND ENG OIL FILTER LIGHTS TURNED ON AND DURING CRUISE THE EICAS MESSAGE ENG OIL FILTER WAS SHOWN. THE FLIGHT CREW PERFORMED THE QRH 7.20 PROCEDURE, CONFIRMING THE FAILURE. DURING MX REVISION, THE MESSAGES 79-31452 AND 79-31462 WERE SHOWN, THE FIM 79-21 TASK 802 WAS PERFORMED AND THE RT ENGINE SENSOR AND OIL FILTER WERE REPLACED IAW MM 79-21-07 AND OPS TEST WAS PERFORMED IAW MM 71-00-00, ALL CORRECT. THE OVERWEIGHT INSP WAS NOT NECESSARY DUE TO THE ACFT LANDED WITH 211,900 KILOGRAMS AND THE MAXIMUM ALLOWABLE LANDING WEIGHT IS 213, 188 KILOGRAMS.
