an insufficiently robust flange attachment hardware design, which failed to contain engine components that were liberated during an LPT mechanical failure, resulting in engine/nacelle uncontainment.   A factor in the incident was the lack of a module-level LPT inspection and the lack of an inspection requirement to detect/monitor  the LPT S4 for advanced sulfidation attack.
