Aircraft Expert on A380 Wing Issues: 747s Have Had Issues Too [VIDEO]

Submitted
A noted aviation expert engineer with 50 years experience said that the wing crack issues that have garnered so much attention with Airbus’ A380 are fairly normal and that they will be resolved. (airnation.net) More...

"A noted aviation expert engineer with 50 years experience" B747 has been around for 42 years..does not land like a navy jet OR flap its wings in the process..why not just come clean..the A388 needs another 100m of float along the runway for a nice gentle landing..why be soo coy about this?

This website wasn't around 42 years ago for us to bash anybody, and instantaneous communication was nowhere around 42 years ago. Hell, CNN just celebrated it's 25th birthday a couple of years back. 42 years ago most folks were still on black & white TV with 3 network channels. They still had the Newsreels at the Saturday afternoon matinees.
Nowadays, if Queen Elizabeth farts real loud, we know about it worldwide almost immediatly!

That's the GREAT thing Wayne..we have this internet..and until they ban people like me off of this site..not unknown at all..same ptincipal as N Korea and China internal affairs by the way..they can hide NOTHING. The idea is that we share what we know so we can help folks..NOT take 'em down. CIA does that stuff well enough.

Hahaha yes I just saw that a couple days ago. Classic!

@Joseph Chan: Furthermore, i think one of the points that the article is trying to point out is, that with any engineering marvel (such as the 747 was when it first came out or the A380 today) there will be issues. Again, nothing is perfect. Also, at the time that the 747 was having it's issues, how many airframes had Boeing built up until that time? I would imagine that such an experienced aircraft manufacturer with decades of experience and thousands upon thousands of airframes built, would have built an airframe (the 747) that would not have cracking issues! Aside from the 747 issue, we have had the airframe issue with the 737 coming apart (SWA 737 last year i beleive) and Boeing not being transparent about a manufacturing flaw that they knew about, but only came out with when the SWA incident happened. Should i start on the 787 issue and how it was 3 years behind scehdule? Or the 747-8 with the rear fuel tank... why with all the marvels of technology today, could they not get that thing to work? In the end, they had to certify the plane without it! Boeing's KoolAid must be really good!

Hang on Alistair who are YOU to call the A388 an engineering marvel..?

Perhaps the word "marvel" is not the right word. Though, in my personal opinion, i do think that it is an engineering marvel to build an aircraft of this size the way Airbus has done it. I am reading this now: Airbus A380: Superjumbo of the 21st Century by Guy Norris and Mark Wagner. Very good book. It is not an assumption that it is an engineering marvel. though, someone saying that Airbus should not make any mistakes at all because of the technology they have on hand, is an assumption.

My 2cts worth on the 737 deal. Best I remember, YES they did know about it but figured it would be many years in the future, but if I remember right in one of the post mortems, it happened many years and land/takeoff cycles before they anticipated. That was one of them things they just flatly didn't know and basically made an educated guess, and it was wrong.

Wayne the fact that it happened stands..the problem is no one knows which serial numbers were effected. Just why it happened again reveals a serious problem in management and a weak leaderhip. Some where in that company is a group of people at the top who should be nowhere near ANY engineering company let alone aviation. In 7/8 years time Boeing is in for a busy time rebuilding many 737NGs and they will settle out of court.

This so call noted aircraft aircraft expert should have noted that went the 747 was designed and build in the late 60s and early 70s, Boeing did not have 5% of the computing power available to Airbus today. With the advent of CAD, advanced modelling software, new materials, superior manufacturing abilities, it is NOT acceptable for a new design to develop wing cracks after such a short service life. Given the technology and materials available at the time of the Boeing design, I can understand if they have some teething issues regarding cracks. In this day and age, for Airbus not to have caught it is worrisome as far as I can see.

You can say the exact same thing about Boeing's 787 delamination problems. Nothing or nobody is perfect. Just because we now have access to some very powerful software, it does not mean what is designed will be perfect. Furthermore, who are YOU to say that it is not acceptable?? Please tell me what credentials you hold to make such an arrogant statement.

Alistair: This is not the first time Boeing has had fuselage parts that were shy when it came to assembly..research the B737NG build problems when parts .. annular chords.. were deliberately disguised with paint to LOOK as though they fitted.. The delamination occured because the material was not fixed to the monoQ. Basically parts rattled themselves apart. Not a design issue...a build quality issue. This will come to light in about 7/8 years at the C checks.

I'll give AB a break. I'm sure they have the engineering talent to build it strong enough to make carrier landings. But then it would only carry 5 pax INLO 500. And that does not fit the design goal. So they push the fine line of weight vs load, just like everyone else. Sometimes they guess right, sometimes not. You just can't out engineer Murphy!

Thanks for posting this Kenneth. Perhaps this will finally put to rest all the Airbus bashing that some folks on here tend to dish out.
