Narrative:
After takeoff, Valujet Flight 224, a McDonnell Douglas DC-9-32, was climbing through about 5,000 feet, when a contained failure of the #2 engine occurred. The flight crew secured the engine and declared an emergency, and the airplane was vectored back to the airport, where a single engine landing was made without further incident. Examination and teardown of the Pratt & Whitney JT8D-9A engine revealed that a turbine blade (part number 823201) in the first stage high pressure turbine assembly had failed due to fatigue. The blade part number indicated that the leading edge of the blade had been reworked in accordance with Pratt & Whitney Service Bulletin 4345 to remove cracking. The engine had accumulated a total of 32,028 flight hours and 25,603 cycles, since last overhaul, it had accumulated 2,794 flight hours and 2,329 cycles.

Probable Cause: fatigue failure of a first stage, high pressure, turbine blade.
