In another picture, I count 23 Fan Blades, not 24. One had a failure and liberated. My guess is at the root where it slides in the disk aka with "a Fir Tree" ( look it up ) What many here do not know is the Jet Engine Manufacturers run a test where they shoot a frozen turkey into an engine at full throttle to make sure it will either continue to run and that a blade will not liberate. On top of that they put a pyrotechnic charge at the base of a blade and deliberately make it fail to see if the containment will hold the blade as it attempt to exit, that is also and FAA requirement for engine certification.

One can ask: Why did this fail on this CFM-56 engine, note they will trace the part back to it's origins as it has a paper trail to determine if it is manufacturing defect or stress over time . Was their a stress-or event, is it a maintenance issue, etc etc.

Any other machinations or theories are folly given the role of the NTSB, FAA and the manufacturer of said engine and or sub-contractor of said part(s). They want to get to the bottom of this, this engine and airframe combo are a big part of the fleet and flights daily, they need answers asap, grounding this fleet is not directive that would be taken without great investigative and engineering thought.

I'll leave this one to the Aviation Pro's not the theorist....

Yes, I see where there’s a blade missing at the 8:30 position.

It’s very odd to me the entire shroud in FRONT of the fan plane is blown away, yet there appears to be no damage to the nacelle interior that lies within the same vertical plane as the fan. I would think this surface would sustain the most bashing from a liberated blade.

Something is weird here.
