## Discrepancy

IAH-  FLIGHT 3797, DURING TAKEOFF THE CREW NOTED THAT THE NR 1 ENGINE HAD A VIBRATION.  THE AIRCRAFT DID AN AIR RETURN, AND LANDED AT IAH WITHOUT INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE NR 1 BLADE, NR 1 PROPELLER ASSEMBLY (DUE TO A WORN PIN/ROLLER ASSEMBLY).  PERFORMED A OPERATIONAL CHECK, NO DEFECTS NOTED AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
