Narrative:

After departing ZZZ and climbing through 9000 ft we experienced a loud bang/yaw. Right engine instruments indicated severe damage. Airframe vibration with throttle at idle. Ran appropriate checklists; declared emergency; contacted dispatch; gave flight attendant's cabin advisory. An uneventful overweight single engine landing was made. Callback conversation with reporter revealed the following information: the reporter stated he received a call from the engine shop supervisor and was advised this was 1 of 2 engines the manufacturer had put a 10000 cycle maximum limit on the turbine. When the reporter was given this information the engine had not been torn down to determine the actual failure mode. The reporter received no follow-up information from the engine shop.
