Looks like someone forgot to lock the latch.

The entire fan disk is gone. Remember United's DC-10 and Al Haine's landing in Sioux City?

The dreaded three engine landing....

The dreaded three engine landing....

Piece of cake.  In the Falcon 50EX losing an engine is an ABNORMAL not an EMERGENCY procedure.   I'm sure the 900 and 7X are the same.

As long as the fan hasn't sliced through something important as it left.

We had an Electra land in ANC in 83 after the prop and gear box came off the #4 engine.  Prop went left under 3 hitting the intake then sliced through belly of fuselage just ahead of wing.  Crew had minimal flight controls, no throttle control....landed without too much drama and no one injured.

Yeah, there's that.   Or the previously alluded to Sioux City event.   Yikes.

Seems similar to the Qantas flight 32, A380 incident, where the intermediated turbine came apart.  I would say something that catastrophic causing the fan disc to come apart would have to be a manufacturer defect, or some undetected fatigue cracking.  Anybody know if Airfrance 380s fly Rolls or GE powerplants?

GE from the article above; but the plane involved in Quantas incident was powered by Rolls Royce. Two similar incidents on same air frame different engines, just guessing maybe not the engines are faulty could be wing design, engine mount vibration control.


"The jet is powered by four Engine Alliance engines, which the manufacturers claim offer $6 million in savings a year with a lower fuel burn, greater range and larger payloads.
According to the company, its GP72000 engine is 'engineered for greater reliability and the lower maintenance costs that come with it'.
Of the almost 200 A380s in the skies, 125 are powered by Engine Alliance engines. "

Is that the one that crashed and they found the engine months later at a corn field?

Yes. I work in non-destructive testing.  That crack was missed a total of seven times due to using trainees to test the engine component. The trainees were under the supervision of a legitimate inspector.  However, due to improper examination technique, by the time the inspector would view the engine component, all the dye would be erroneously removed from the crack. That crash should have never happened.

No, with the Qantas 32 accident it was definitively concluded to be a powerplant defect.  Specifically an oil stub pipe which was bored out of alignment, causing it to fail, which lead to oil starvation of the intermediate turbine bearing, as well as an oil fire. Result was said turbine wheel coming apart, which wrecked a lot of other stuff as the shrapnel cut through the wing.  But Rolls Royce fixed that, and as you say this is not a RR engine.

Just pure speculation, but this does seem more like the DC-10 incident many years ago that others have mentioned, where a material defect in the fan disc went undetected, eventually leading to it coming apart.

If anyone knows the exact number of times a cracked component was not reported as being cracked, somebody knew it was cracked from the start. Sounds like somebody was covering their arse and passing the buck to the trainees.

They knew that the crack had not just formed instantly, and they knew how many times this particular component had been tested.  That's how they deduced it was missed seven times.
