## Discrepancy

FLT 2739 FROM ATL TO TOL.  DURING CLIMB OPERATION AN AIRFRAME VIBRATION WAS NOTED AND ISOLATED TO THE NR 2 ENGINE.  AIRCRAFT RETURNED TO ATL WHERE IT LANDED WITHOUT INCIDENT.  POST FLIGHT INSPECTION WAS PERFORMED.  IT WAS NOTED THAT THE 8TH STAGE DUCT SEPARATED AT THE SADDLE DUCT CONNECTION.  THE SADDLE DUCT WAS RECONNECTED, OPS AND LEAK CHECKS GOOD.  NO OTHER DEFECTS WERE NOTED.  AIRCRAFT WAS RETURNED TO SERVICE.
