Airbus A380 Wing-Fuselage Testing

[gfemg]

As a pilot with college training in strength of materials used in aviation I am disappointed to see that Airbus is downplaying the issue of cracks being discovered in many of their A380 aircraft. Cracks appearing on structural components inside a wing are a very serious matter and in this case enough to prevent me from stepping foot on any A380 until the matter is fully and properly addressed. This situation calls for the grounding of the entire A380 fleet for inspection & repairs as required.

[gfemg]

We must never forget the lessons learned from the Comet - the first passenger jet in service. It took 3 in-flight breakups of the Comet before they were all taken out of service for a total re-design. We can't afford to have an A380 break up in flight - it would be a disaster on a massive scale. Cracks in wing structural components are the early warning signs of a disaster in the making. Airbus needs to immediately ground every A380 & FIX the problem NOW Before an A380 breaks up in flight.

[Pvjinflight]

@gfemg Those parts where cracks appeared were not any important structural components, and problem is being fixed. I doubt that pilot that is trained to fly a plane knows better than aircraft engineer that is trained to design planes. If there was any danger 100% surely Airbus would ground entire A380 fleet as letting one of those crash because of them would cause huge impact on their image and sales. Airbus is not like Mcdonnel Douglas was.

[gfemg]

@Pvjinflight Airbus aircraft that fell out of the sky - the American Airlines Flight 587 - an A300 that lost its Entire Vertical Stabilizer and fell out of the sky and crashed into lower Long Island NY setting multiple homes on fire and killing 261 people and Air France Flight 447 - an Airbus A330 that fell out of the sky over the Atlantic Ocean - crashing into the ocean and killing all 228 on board. The entire A380 fleet must be grounded ASAP and FIXED before any of them fall out of the sky!

[Pvjinflight]

@gfemg Yes it lost whole vertical stabilizer because pilot mishandled controls because of false training program. Could have happened to any Boeing plane too, if you constantly put rudder from full left to full right it creates very high G forces that will eventually break something.

AF447 crashed because 1. pitot tubes failed because of design problem, they were not made by Airbus and problem was known but Air France was too lazy to change tubes in time.

[Pvjinflight]

@gfemg And 2. Only pitot tube failure does not crash the plane, there is corrects procedures and if you follow them you can keep constant speed and altitude. However pilots of AF447 did not do that, but they let plane to stall and after that they really did not detect whole stall but just kept pulling up instead of pulling nose down.

I doubt that some real commercial pilot would be that hysterical about small cracks on non vital parts.

[Pvjinflight]

@gfemg Also I can remember some time, like a year ago video filmed by passengers where parts 757´s wing were cracking midflight. However they did not make emergency landing and whole 757 fleet was not grounded. Cracks do develop to all aircrafts at certain point, thats why they are checked. Probably Airbus will alter their A380 design on those parts so it wont happen in future, but there is no need to hysterically ground whole fleet for that.

[gfemg]

SHAME on Airbus for having the nerve to say the cracks being found inside the wing structure of one A380 aircraft after another are on a "non-critical” part of the wing! EVERY internal structural component of a wing is an integral part of the entire wing structure. Cracks appearing on any structural component in a wing can potentially comprise the overall structural integrity of the entire wing. This is a serious matter that can cause an A380 to break up in flight & Must be FIXED ASAP!

[hillberg100]

note the amplatude of the tests, Not the same ,If its not boeing I'm not going

[Pvjinflight]

@hillberg100 faggot

[3snowyman]

@Pvjinflight Why go there? At least Boeing doesn't sell planes with cracks in the wings...

[Pvjinflight]

@3snowyman Those cracks on A380 are no problem, just minor thing on parts that are not actually important to aircraft structure. They will be checked frequently from now, and in future A380s there will be no problem.

Also did you know that just about 20 years ago all Boeing 737´s had fault that could jam the rudder to its full left or right position and crash the plane. After two planes crashed and third almost crashed Boeing found the fault and fixed it, but many people already died.

[Pvjinflight]

@3snowyman Also on early 747s there was cargo door problem where it could open in air because of technical failure and make huge hole to plane. That happened, and many people died when they flew out the plane after cargo door opened midflight and made big hole to the fuselage. It was saved from crashing only by crews very big professionalism.

So like you can see Boeing has had way bigger faults on their aircrafts in history.

[3snowyman]

@Pvjinflight You didn't answer my question about calling a guy a fag... But anyway, this was what, 40 years ago? We're in 2012 dude. You would think that selling a plane with cracks in the wings wouldn't be a problem.

[Pvjinflight]

@3snowyman Whats the difference? Today planes are designed with computer, 40 years ago by human. Still humans build those computers and use them, so little miscalculations and stuff can happen.

Also that B737 thing was still existing in 90´s when those crashes happened.

[encinobalboa]

The footage of the wing breaking is from the 777.

[lejejzerman]

Die FEM Simulation ist sehr sehr .... schlecht ;)

[jeetendrag10]

only idiots with no engineering background compare airbus with boeing.

you have to compare airplane part by airplane part to see any difference in the two makers.

airbus v/s boeing is a non sense comparison,as only few things are similar or comparable.

[uspatriot08]

Boeing is still the better plane maker!

With static test exceeding ultimate load, that just shows you how quality surpasses quantity.

[sirtodi]

@uspatriot08

"boeing is still the better plane maker!" .... means nothing from a guy called us-patriot ;)

[slickfast]

@uspatriot08 Uh... that's an engineering standard, pal. I'm an American aircraft engineer working for an American aircraft company, and I'm not against our country. Safety factors are in place and required to pass any kind of federal certification process. In short, they both have to do the same thing. Now, does the Airbus' failure look worse than the Boeing 787's wing test? Hell yeah.

[onecunningfox]

Airbus has only ever completed a 100% Wing Load test. Not even close to the 150% that Boeing does.

[Exagerative]

sehr gut. :)

[Moayyed787]

THERE IS A 100% SAME VEDIO FOR bOEING 777

SOO ?

[fffatamorgana]

just a quick translation:

what they are doing is simulating extreme weather conditions using hydraulic presses. the test is done in dresden(germany) over a one year period, simulating the equivalent of 25 years of flying or 47500flights. it was the most extensive testing ever done on a commercial airliner.

hope that helps...

[jannej312]

They are talking about that in an other test they go until the wing is totally destroyed. So they are telling you that the test which distroys the wing is not from Airbus!

[yogods]

hey!! what happen here??

This is the same images of the wing test of the boeing 777 look this video

youtube . com / watch?v=pe9PVaFGl3o

Airbus is SCAM???

[tjp353]

It's strange that the under wing access panels aren't fitted as they're load bearing components. I suppose the engineers didn't think they were necessary since tests like these typically result in the top skin failing through compression (as this did) rather than the bottom skin through tension.

[milabueno]

underwing access panels are not structural. The only loads in this are are through the skin because the access panels are between wing rib positions.The access panels are removable components attached with screws into anchor nuts.The skin itself is thicker around the access holes to carry the skin load around the cutouts.

[BartekAirbuscaptain]

airbus rocks down with boeing

[crapper1]

i was looking for the wing testing of the a380 thank you for posting this them things bend alot to begin with

[tjp353]

crapper1. I've been looking for A380 wing testing vids too. The destructive testing at the start of this video, however, is footage of the Boeing 777 wing testing. Compare it to 'B777 Wing Eltimate load test' on Youtube to see for yourself. Only after 00:18 seconds does this video show A380 testing.

[dkorda]

Airbus has gone though five CEOs as multiple delays in the A380 program resulted in massive write-offs and a restructuring plan that foresees 10,000 job cuts over four years — not to mention billions of dollars in lost profit.

Such delays have hurt more than just profits: Airbus' reputation has suffered, and U.S. rival Boeing Co. grabbed the top sales spot in 2006.

[pasoplaya]

damn nice

[dkorda]

Airbus originally projected it would break even on the A380 with its 270th delivery of the jet, but that break-even number has ballooned to 420 following the model's costly delay problems. AP says Airbus currently "has logged 189 orders or firm commitments for the plane."

[tjp353]

dkorda. Shouldn't be a problem since both Boeing and Airbus have forecast a requirement for significantly more than 420 aircraft of 400+ seats. This will be shared between the A380-800 and 747-8I. Considering the A380-800 is currently outselling the 747-8I by 8 to 1 (Lufthansa is the only airline customer with 20), if this trend continues and Airbus'/Boeing's forecasts are correct, the A380 will easily break even.

The 747-8 looks set to be relegated to freighter duties (-8F has 80 orders).
