## Discrepancy

THE FLIGHT CREW REPORTED OF A "GEN 1 BEARING FAIL" ADVISORY MESSAGE DISPLAYED ON THE EICAS SYSTEM. OPERATIONS WERE CONTINUED PER MEL. THE MAINTENANCE VENDOR DETERMINED THE LEFT OUTBOARD POWER UNIT WAS DEFECTIVE AND WAS REPLACED WITH AN OVERHAULED UNIT. GROUND RUNS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
