Boeing suspends testing of 777X aircraft
Boeing Co on Saturday announced it had suspended testing of its new widebody 777X aircraft as media reports said a cargo door failed in a ground stress test (uk.reuters.com) और अधिक...Sort type: [Top] [Newest]
“Exploded outward” - as in blew completely off the fuselage or just severe bulge causing structural damage?
Never mind, I found a different article to answer that question. The hangar was empty during the test and the door did blow completely off.
I can't wait to hear DonQuixote make ridiculous excuses and say this isn't important or serious, just fake news.
they are testing, they have not stopped testing, they cannot cease testing because they want to make the aircraft safe so they can sell it. New tests will in due course be done and when the tests are done Lufthansa will get their new planes and boeing can begin to wipe the egg off their faces.The days of overbuilding components, like in case of the c-47/DC-3 are long gone, so that particular subcontractor goes back to the drawing board, err computer screen and begins anew.
It doesn't say "stopped" testing. If you could read, you'd see it says "suspended" testing. They can't continue testing until they investigate what went wrong and take remedial action. That should be obvious.
The stopped Load testing the 777X they are still testing the other systems etc.. They dont know when they will get back to actually load testing the aircraft due to the cargo door failure.
Boeing's own media release says: "...an issue arose that required the team to suspend testing."
And: "The testing issue occurred during the final minutes of the test, at approximately 99 percent of the final test loads, and involved a depressurization of the aft fuselage."
And: "The static airplane has been successfully undergoing testing since June, and this was the final test for the static test article." What else are they "still testing"?
More than just the door failed, by the way. The rear fuselage broke and that let the door burst free.

Actually it was final load tests, so yes, other testing is suspended. Probably not for long thou, as it seems it was an actual "over" test. I think Boeing, and I hope I'm incorrect, thinks this airframe can behave like the 787. Aluminum alloys do not behave like composite materials such as carbon fiber.
The incident, first reported in the Seattle Times, happened on Thursday afternoon at Boeing’s widebody facility in Everett, Washington. The so-called ultimate load test forces the wings to bend to 150 percent of the maximum load they would likely encounter in flight while pressure gets applied to the skins of the wing and fuselage. In this case, a cargo door blew off its hinges under the extreme pressure, forcing Boeing to investigate the cause and possibly revisit design details. The overall testing program continues, however, according to a Boeing spokesman
