notarboca, I'd be very surprised if Airbus *didn't* do the type of tests you mention. The 15 slides shown in my previous story on the 350, "Slideshow: Anatomy of a Composite-Heavy Jetliner"
http://www.designnews.com/author.asp?section_id=1392&doc_id=264009
are a mere smattering of all the various press releases and announcements made on the many, many steps during this entire process, and many of those represent a ton of different tests. Commercial aircraft must go through a very rigorous testing process, much more extensive than that of military aircraft. We've discussed this, regarding composites, here:

Airbus seems to have learned from Boeing's mistakes.

Good point, Ann. Even though it is old tech that is giving the 787 trouble, someone must be overlooking the old tech. Perhaps they've been overly focused on the new tech.

Ann, TJ-- I, too, would like to see composite fatigue results.  Fatigue kills airframe components!  The only way the US Air Force has been able to keep B-52s airworthy is to address this, since the wing flexes about 6 feet with every takeoff and landing cycle.  Quite a maintenence effort.

I doubt Airbus has taken a horizontal stablizer into a test bed and twisted/jerked it six ways from Sunday to see fatigue results.  Most probably rely on computer modelling, but I hope not.

@Murray: Yes sounds like that to me too. You need to provide the fullest support towards industries like aviation since they are the things which carries the industry forward if its right on track with technology.

Yes, I saw that poll. That's the power of bad press. The fact that this is old tech, not new tech, at fault makes me nervous, because that indicates a systemic problem, like one of QA/maintenance. If anything, you'd think those oversight-type systems would be tightened on the 787 by now, not loosened.

Good question, Ann. If it's not new technology, why is there a problem? Also, have you seen the Design News instant poll on whether readers would be willing to fly on the 787?

Thanks, Rob. So now it's a brake indicator problem--not exactly new technology. At least the most recent problems have been mechanical, and not related to new technologies. OTOH, one wonders why they happened at all.

Ann, a 787 was diverted for mechanical problems on Sunday:

Boeing has really had its problems, even just this week. It will be interesting to see if Airbus has similar difficulties.

The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
