## Discrepancy

MAINTENANCE INSPECTED THE AIRCRAFT AND FOUND THAT THE #1 GENERATOR HAD SUFFERED A CATASTROPHIC BEARING FAILURE CAUSING THE GENERATOR TO SEVERELY OVERHEAT. MAINTENANCE REMOVED AND REPLACED THE AFFECTED GENERATOR AND SEVERAL OTHER PARTS ON THE #1 ENGINE INCLUDING THE GEAR BOX, #3 GENERATOR, AND PMA AS A PRECAUTION. OPERATIONAL AND LEAK CHECKS WERE PERFORMED SATISFACTORILY AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
