Boeing 777X’s fuselage split dramatically during September stress test

Boeing got an unexpected jolt in September when engineers in Everett put the new 777X airframe through an extreme test of its structural strength. Just as the test approached its target stress level, an explosive depressurization tore through the fuselage.

Boeing has kept the details secret, but photos obtained by the Seattle Times show that the extent of the damage was greater than previously disclosed and earlier reports were wrong about crucial details. The test plane is a complete write-off, its fuselage skin ripped wide open just behind the wing. A passenger door that blew out and fell to the factory floor was a secondary impact of the initial rupture, which was located far below the door. The relatively good news for Boeing is that because the test failed so explosively at just 1% shy of meeting federal requirements, it will almost certainly not have to do a retest. Regulators will likely allow it to prove by analysis that it’s enough to reinforce the fuselage in the localized area where it failed.

Wait? So it failed horribly but because it waited so long to tear open they can just “fix it” and not have to prove it is fixed? Have they learned nothing?!

That’s why they test

It was an extreme stress test on the airframe. It was within 1% of the maximum limit when it depressurized.
This is classic AirBus / EU negative propaganda. Boeing is and continues to be the most trusted aerospace company in the world.

If those stresses occurred in a real life situation you are likely about to die anyway. And other parts of the plane would be gone already.

You say this in every Boeing thread. Whether you like it or not, “most trusted” is demonstrably false at this point

I’d have to know what the target stress level was before I flip out over this. I mean, if the target is purposely set at an insanely high level that would never be attained short of a 1 in a billion scenario and this was the only part of the airframe that failed within 1% of that target, then it seems reasonable to say that this is the part that needs work.
Plus I’m sure that Boeing is motivated to address the issue effectively anyway, seeing as the company likely wouldn’t survive a catastrophe that could be associated in any way with this particular result. The bad PR surrounding the 737 Max did them enough damage already.

Yes, the Seattle Times is working with the EU to take down Boeing

Son, these are real planes, not make believe. They should stay together up to their ratings, and any good aerospace company would add some safety margin.

I am going to type slowly so you can understand.
This was a test fuselage and was used to test the structural strength of the new design. It failed 1% shy of the target which was 1.5 times more severe than anything the airframe would encounter in the real world.
The test was designed to give the engineers the data they needed for certification. The test showed that for all practical purposes, the airframe passed and only minor reinforcement will be required.
Airbus had a similar failure on the A380 wing test which failed within 3% of the target. You can be assured that Airbus did not text another A380 wing.

I wonder if that KC46A Pegasus based on the 767 might ever face those kind of stresses. You know, maybe while dodging Air to Air missiles or MiG's or something of that nature.
Had Airbus gotten that contract we would have had a proven design in the air years before, hell the Air Force is still having issues with the KC46. They DID get it before Democrats stepped in and do what they do, stealing it.
This was Obama playing politics and giving Boeing and Washington State a contract instead of Alabama and Airbus. I know quite a bit about this little fiasco living in Mobile.

These morons have zero experience in this industry and they just regurgitate whatever fake news propaganda that AirBus and/or the EU puts out. It’s scary actually to see the level of corporate disinformation that is resonating within mainstream America that was devised by EU IO operatives.

A KC46 dodging MiGs and SAMs? The KC46 is not an air supremacy fighter. If they are dog fighting MiGs we’ve got issues. Boeing is not responsible for the fiasco with the KC46 it’s DoD contracting / acquisitions to blame.
