Wing Spar Crack Repairs Slow Down Airbus A380 Return To Service

1년 전 제출됨

Operators of older Airbus A380s are finding that cracks in some areas of wing spars are making a return to service a significantly longer process, as inspections and repairs take weeks to complete. (aviationweek.com) 기타...

Flex Seal is the appropriate fix for sure.

Too expensive. Duct tape will do the job!

Is there a market for duct tape in carrier colors?

I’d like to see someone cut the wing in half, then repair it w/Flex Seal & fly the plane. ‘Just like on TV !!!’

I'm 90 years old, I think the DC 3 was born the same year as me, 1932. Great airplane, many trips in one while in the R.C.A.F.

The amount of flex in these heavy aircraft, large span modern wings during high AOA low or high airspeed events, (takeoff and landing, turbulence), means modular elasticity will have a predictable effect on aluminum and other highly stressed metals over numerous cycle events. 787's are having similar issues with titanium stringer/longeron to spar attach fittings, which is exactly what is really goin' on here.

Do de maff, don't bend the wings too much.

“there are cases in which wingboxes were produced years before actual entry-into-service of the aircraft, meaning “younger” aircraft can be affected, too, if wings had been stored for an extended period.“

Not my field of expertise, but the suggestion that the wing boxes begin to fail in storage after production but before entry into service seems to beg for skepticism. Is the 7449 composite made from banana peels?

As an auto tech / small engine mechanic, I'm used to automakers & outdoor power equipment manufacturers cutting corners on metal (and a million other things) to save a buck. I sure hope this trend isn't making its way into aviation ...

Definitely not good.
Airbus should study DC-3 design. Some of those planes are older than I am (83)and still flying

Hmmm what is the weight difference between those two planes? And how many lbs per square foot of wing?

The -3 is not a pressurized aircraft and as such is not subjected to the level of metal fatigue found in aircraft structures that are pressurized.

The A380 wing spar structures are not subject to any pressurisation cycles or loads, so this is irrelevant. But we are talking about components far out on a wing that carries enormous loads which vary greatly. I suspect that the engineering challenges are very different from those faced by the DC-3 designers.

The mentality of the folks at Airbus baffles me. Chunks of paint and composite, wing cracks, etc. none of that constitutes a problem to them. As airframe manufacturers, they certainly are arrogant. I am sure some of their customers and some of those who might be a customer some day are thinking the same thing. They don't stand by their products, and nothing is a problem. I would not be too encouraged to buy from them. All commercial and military airframe manufacturers have had to deal with wing cracks from time to time. They figure out a fix, take care of it, and move on.

They don't stand by their products,

I note that the story says that Airbus are doing the work - “Airbus is fixing everything..."

With these issues surfacing, maybe Boeing could have found a market for the 747-8 as a replacement to the 380 which will become too expensive to fix. Wing issues to my knowledge is something that did not affect 747's.
