So where we stand is Boeing continues to develop a fix for the issue and as yet has not released publicly any details, though off-the-record claims and rumors are circulating.

All in all to me that is very disappointing. But there is not much we here on A-net can do about it. I hope they get the program on the right tracks. Because that is where it belongs. Hope (though I am not confident) that Boeing will give a clear and honest update soon.

There are 3 parts to the wing in a Boeing design. The center wing box and the two outboard wing boxes. They are all part of "the Wing" The wing sections are connected on either side at the "Side Of Body" SOB rib joint. This is the production break. Look at all those prior images of the sections. Per all the releases, no one has said there is any reason to suspect the fuselage to wing integration, therefore there is no reason to take the wings off.

You can not say that anything has changed from a month ago just because a Times reporter can't use the same terminology right twice.

And for the engineers out there... did any of you really think that Boeing could only fix one side of a joint?? Really? Any free body diagram of any joint says if you beef up one side, you beef up the other to match.

Reporters don't take basic statics... engineers do in their first year of college classes.

I don't care if its Boeing or Airbus... basic engineering says this is not a new discovery, no matter what some interiors engineer says to the press.

After reading a blog about the B787 delay in Seattle Times I wonder if maybe Airbus' approach to compsites on the A350 using panels is the best way to go for now.

" You have to remove and replace the whole damaged skin (because it is hard to repair composites), not just trim the stringer web at the ends which might not work (if not causing more damages.) This means you have to remove hundreds even thousand fasteners common to the panel. "

This has nothing to do with delamination at the 787 wing root. The panel or barrel design relates to the fuselage, while the A-350 wing design will most probably look very similar to the 787 one. The A400M wing is already a composite wing, with CFRP stringers and panels, just like the 787 wing. Expect the A-350 wing to include even more composite parts.

Some additional details from Seattle Times http://seattletimes.nwsource.com/htm...aerospace/2009565319_boeing30.html

Key points include:

- Damage occurred at limit load, not ultimate load
- Damage occurred at both sides of wing body join
- Fuselage damage means fix is harder
- Responsibility was Boeing's, not suppliers
- Total cost overrun on 787 is now $11B
- First flight unlikely until next year

Wow:

"The [787's] wing damage [...] occurred under less stress than previously reported — and is more extensive."

"[it] happened when the stress on the wings was well below the load the wings must bear to be federally certified to carry passengers"

That should be interesting for those people who keep claiming that the 787 would "practically" have been capable of starting the flight test program, but Boeing decided to postpone as a mere "precaution".

It's also the first time I question the announcements in Paris. Given Boeing knew they had wing damage at limit load (i.e. at 100% of normal/routine loading) several months before Paris, it's hard to see how they could say first flight was "imminent".

I sense an investor lawsuit now...

Boeing's woes have nothing to do with their approach to how they construct their CFRP airplane, but it has everything to do with how broken their organization and, in particular, their leadership has become. I haven't lost faith in CFRP as the future of aviation; I have lost faith in Boeing's executive management team.

Cost overrun of $11 billion? I cannot fathom how no one in their C-Suite has taken a fall for this. What the f*** ever happened to accountability????

Well, it didn't take a genius or an insider to figure out that was going to happen.

Possible? Yes. Likely? No.

It's a bit of a guessing game as Airbus is very quiet about the A350 at the moment (probably not a very good sign) while Boeing, which has lost a lot of it's scheduling credibility, hasn't even put out a new schedule one might or might not believe.

Official A350 statement from the conference call was "on track for the time being".

Because it's still less than what the Board of Director's signed off on as a maximum figure?

Plus I cannot believe the cost-overrun is $11 billion unless they're counting all the inventory as an "overrun", which is a bit disingenuous, IMO. Total spend to date of $11 billion? Sure.

While it was an analyst estimate, it did not include inventory or total spend. The exact quote is

Quote:

In a note to clients, Campbell estimated the total cost overrun of the Dreamliner program so far — extra startup and engineering costs, penalties owed to customers for delivery delays and contractual obligations to suppliers for engineering changes — as "in the vicinity of $11 billion."

Well I think his estimate is full of "weapons grade balonium" and I don't say that just because he is talking about Boeing or the 787. He's projecting a cost overrun equal to the entire program cost and I find such a thing both fanciful and farcical.

"The [787's] wing damage [...] occurred under less stress than previously reported — and is more extensive."

The statement about the level of load at which the damage occurred is an error in the Seattle Times' reporting, as it states in the article, not a change to what Boeing has said. Boeing has only stated that the damage occured during the limit load test, and they have only stated publicly that the test went to limit load. The figure of 120-130% is from Flightblogger's sources. The damage happened at some point below that load, but I don't believe Boeing has stated how far below.

Publicly Boeing has given very little information about exactly what the damage was, so it's impossible to say with certainty whether the change in the extent of the damage reported is due to more information coming out or is an actual change. Certainly at the original announcement they downplayed the work required. My belief is that the change between this week and last is more information not more damage, but that what is being reported now is definitely more than Boeing let on at the delay announcement.

For argument´s sake, Airbus is behind on Boeing with regards to this particular type of plane so isn´t an insider very handy to look at the wing problems etc Boeing is facing?
Or if we assume the 787 won´t be flying for a while yet, wouldn´t a pair of Boeing eyes in Toulouse not be very convenient?

Just asking.........

Not entirely correct.

No airliner is *anticipated* to be treated to limit load during its service life.

But it happens from time to time that limit load is exceeded. Then that particular plane must not fly until it has passed a relevant structural inspection.

In other words, as long as you don't exceed the limit load, then you go and can fly the plane again. Instead of putting it into a hangar for days or weeks of inspection work.

For certification the manufacturer must prove 150% of limit load. Those extra 50% shall cater for safety margin, production inacuracies, and fatigue developing during service life.

I have to agree with Red Flyer, well said. This plane will fly and I'm sure it will ultimately be successful. But there's no question Boeing bit off way more than it could chew with a new material type, a new construction method and new supplier network/relationship structure. All in all this one will go down as the worst blunder in Boeing's history, and I'm sure it'll be the stuff of legends in the Harvard Business Case library. My guess is that McNerney and several others will be gone by year-end and we may see a hard play to get Mullaly back from Ford. That alone would go a long way to restoring some confidence in the employee base and the customers as well.

All this said Boeing isn't alone in its misery. Airbus has back to back new airplane intros of 2 years for the 380 and 4 years running on the A400. So it's not like Boeing is alone in the Hall of Shame. But I do agree with Red Flyer, Boeing's management team should be sacked immediately and a team of hard-nosed engineers with decades of experience putting planes together brought in the clean up this mess. Mullaly would be a start.

Chuckle, chuckle. I am the architect/technical lead on a project at my current client, and this is what our PM tells inquirers even when we already know we have troubles that we cannot solve during the project's remaining scheduled time. What we do is "socialize" the idea that we are having problems, with the department's director, who then "socializes" it elsewhere. Then the official announcement isn't such a hammer.

And it would be disastrous for Ford and its shareholders. I bought Ford stock when they named Mullaly CEO. While I believe he could do for Boeing what he has been doing for Ford, I would rather he continue to do it for Ford!

290 Dynamicsguy : The problem with building parts like this is that you tie up capital in parts and assemblies. This goes against the Lean+ mantra at Boeing. There is

298 EPA001 : That is my understanding as well. Percentages and absolute weights are really two different things in this discussion. Great post Zeke!
299 RIX : - a non-ER one? Hardly the case, 330 has nothing to do with it. And, anyway, Boeing did nothing to replace it, other than 787-3, which was hardly a p
300 Pygmalion : Have to disagree with both you and Zeke. It has nothing to do with poundage of CFRP or percentage of some all up weight. it has everything to do with
