The Part that Broke in Charleston is a Turbine shaft made by IHI of Japan. They are thinking the 747-8 that had an engine let go in Shanghia has the same problem.
When the LPT Turbine shaft breaks, the LPT turbine wheels overspeed and it’s only a matter of time before all of the blades fly off and if it continues to spin, catastophic, uncontained disk failures can result.

The same company that made the turbocharger for my MX5.
Interesting.
Someone is definitely going to get shafted over this mess.
Is it too late to put in some Rolls Royce engines?
Presumably the engine control shuts the fuel down immediately upon sensing the turbine overspeed. However, I wonder if it continues to windmill during flight; I suppose this could be a problem.
