Narrative:

Experienced a turbine rotor failure and subsequent partial rotor separation from #1 engine. Declared an emergency and returned for normal single engine approach and landing. No known deviations from ATC clearance or emergency procedures. Callback conversation with reporter revealed the following information: the airplane was an MD80 and the failed engine a pratt and whitney JT8D-217C. Engine was replaced and the reporter has no information on the cause of the failure. The failure appeared to be contained but the containment ring was extensively damaged. The FAA has not contacted the reporter.
