Narrative:
In cruise climb, a sudden onset of a steady, pronounced vibration occurred. Captain immediately troubleshot problem and determined #2 engine was vibrating and had to be shut down. No power setting alleviated the vibration. We declared an emergency, got vector for mwh, completed emergency and normal checklists, and landed with 1 engine, uneventfully, at moses lake airport. Mechanics found lp turbine blade missing. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a fokker 28-4000 with 2 rolls royce rb-183-555-15P engines. The reporter said the turbine failure resulted in an engine change at the diversion airport.

Title: A FOKKER 28-4000 IN CLB AT FL180 DECLARED AN EMER AND DIVERTED DUE TO #2 ENG HIGH VIBRATION CAUSED BY TURBINE FAILURE.
Narrative: IN CRUISE CLB, A SUDDEN ONSET OF A STEADY, PRONOUNCED VIBRATION OCCURRED. CAPT IMMEDIATELY TROUBLESHOT PROB AND DETERMINED #2 ENG WAS VIBRATING AND HAD TO BE SHUT DOWN. NO PWR SETTING ALLEVIATED THE VIBRATION. WE DECLARED AN EMER, GOT VECTOR FOR MWH, COMPLETED EMER AND NORMAL CHKLISTS, AND LANDED WITH 1 ENG, UNEVENTFULLY, AT MOSES LAKE ARPT. MECHS FOUND LP TURBINE BLADE MISSING. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A FOKKER 28-4000 WITH 2 ROLLS ROYCE RB-183-555-15P ENGS. THE RPTR SAID THE TURBINE FAILURE RESULTED IN AN ENG CHANGE AT THE DIVERSION ARPT.
