## Discrepancy

AIRCRAFT RETURNED OF FLIGHT DUE TO DURING CLIMB, THE RIGHT ENGINE PRESENTED LOW OIL PRESSURE AND QUANTITY; SO FLIGHT CREW IMMEDIATELY PERFORMED THE RIGHT ENGINE SHUTDOWN. MAINTENANCE PERSONNEL PERFORMED REVISION TO RIGHT ENGINE, DETECTING THE LUBRICATION UNIT FAILED IAW AMM 71-00-01; SO THE LUBRICATION UNIT WAS REPLACED IAW AMM 79-21-01 AND OPERATIONAL TEST WAS PERFORMED IAW MM 71-00-00, TESTED CORRECT. THE OVERWEIGHT LANDING INSPECTION WAS PERFORMED IAW AMM TASK 05-51-35-210-801, NO DAMAGES WERE FOUND.
