Dollar to donuts an engineer somewhere sounded the alarm months ago only to be told to shut up by “management”.
Out of curiosity, were the GE engines manufactured in a union shop in Ohio, before being sent to the Boeing facility in right-to-work South Caroina?
The unions are very unhappy about the South Carolina plant. Just saying....
Everything that is GE is a piece of crap. Like my stove, and refrigerator etc;
I remembered from 50 years ago that GE manufactured engines in a suburb of Cincinnati.. I went looking to see it it had all been outsourced to Red China. Nope. But I could not verify where the failed parts were made.
Looks like quite a bit of interesting stuff at that site.

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.
Boeing doesn’t work on the engines.
Wish there was more info here. Does this mean that all GEnx powered aircraft are grounded, wherever they are? How many aircraft are affected? Where? How many passengers will be stranded in airports worldwide?
and I thought spending 3 hours pulling/replacing wiring because a new GE ground fault kept tripping was a pain in the rear. In the end, a new GFCI from a different company fixed the original problem. (original GFCI would not reset, GE one would trip randomly)
Turns out the GFCI outlet is not much better than their plane engine.
at least no one would die if the GFCI tripped when it should not have.
GE paying their fair share yet?
The fan shaft forms the low-pressure spool of the GEnx-1B engine and connects the fan stage with the low-pressure (LP) turbine. The shaft is made up of two main sections, and the failure is thought to have emanated in the torque-retaining nut connecting the two. The NTSB says the GEnx engine “fractured at the forward end of the shaft, rear of the threads where the retaining nut is installed.” It adds that the fan mid-shaft is “undergoing several detailed examinations, including dimensional and metallurgical inspections.”
Investigators and a team of experts from the NTSB, FAA, Boeing and GE specializing in engine systems and metallurgy found the small fracture leading to the aft part of the shaft, which is made by Ishikawajima Heavy Industries of Japan.
The fracture in the shaft assembly allowed the rotating LP turbine to move aft, clashing with the LP stators. The impact caused significant damage to the LP turbine section, pieces of which were jettisoned from the engine exhaust. The hot parts exited the engine and sparked a grass fire by the runway which caused the airport at Charleston, S.C., to be briefly shut down. The engine was powering a 787 on a pre-first flight high speed taxi run. The aircraft was the second to be completed at Boeing’s Charleston site and is destined for delivery to Air India.
The fan shaft is designed to separate in extreme stress events to avoid over-speeding the LP turbine and risking an uncontained failure.
A similar incident occured in Japan recently.
Junk engines.
