Cruising at FL310, the no. 2 engine first stage turbine disc separated, causing an uncontained engine failure. Turbine debris penetrated the fuselage structure and caused depressurization. The pilot made an emergency descent and landed at Charleston.
PROBABLE CAUSE: "Engine and airframe failure were caused by the the separation of the first stage low pressure turbine disk. The disc interstage seal was installed inadequately, resulting in rubbing between the seal and disk, causing failure of the disk. Inadequate procedure by maintenance personnel are a contributing factor."
