Production of Boeing 787 Dreamliner Delayed Again
Hugh Pickens writes "Boeing has discovered microscopic wrinkles in the skin of the 787's fuselage and has ordered Italian supplier Alenia Aeronautica to halt production of fuselage sections at a factory in Italy. 'In two areas on the fuselage, the structure doesn't have the long-term strength that we want,' says Boeing spokeswoman Lori Gunter. To repair the wrinkles, additional layers of carbon composite material are being added to a 787 at the South Carolina factory and twenty-two other planes must also be patched. Production of the 787 has been fraught with problems with ill-fitting parts, casting doubt on Boeing's strategy of relying on overseas suppliers to build big sections of the aircraft before assembling them at its facilities near Seattle. The 787, built for fuel efficiency from lightweight carbon composite parts, is a priority for Boeing as it struggles with dwindling orders amid the global recession. Customers had been expecting the first of the new jets in the first quarter of 2010 — nearly two years earlier than they will be delivered. The delays have cost Boeing credibility and billions of dollars in anticipated expenses and penalties. Orders for 72 planes have been canceled already this year, although Boeing still has confirmed orders for over 800 aircraft."
where I point out that maybe if they'd kept those jobs in the United States instead of tying to save a few pennies or getting a contract or two from a state airline that the parts might actually work right the first time.
Yes, companies that send jobs overseas, I'm looking at you.
"Boeing has discovered found microscopic wrinkles" ? Huh?
... an EADS executive is laughing with glee...
Sounds like the start up of the 747. Boeing nearly bankrupted the company by pushing the envelope in plane design and manufacturing when many people didn't think the business model would work out. They're at the same point again for the same reasons, so we will see if they can do it again.
But Boeing is lots more than the Commercial Airplane group; I believe they are the number one or two US defense contractor so even if the 787 takes a long time to break even, the company will still survive.
If, however, the plane actually flops because of the choices they made (heavy use of composites PLUS heavy outsourcing), then Commercial Airplane may lose enough money to trash the company.
Remember folks, this is why you pay your high end executives lots of money....
Faster! Faster! Faster would be better!
Now Boeing can finally pin the blame for all the delays on another company again.
Excuse me, but please get off my Pennisetum Clandestinum, eh!
All this is because of American companies' belief in complexity. We should borrow a leaf from the Russians who I believe, are champions of simplicity which actually delivers.
Another victory for outsourcing your core competency.
This Youtube video was sent to me from a friend that works at Boeing (not in the commercial division). About sums things up.
Boeing is designing a permanent fix to the wrinkle problem so future versions of the plane won't have to be modified. The existing fuselage wrinkles, she said, will not compromise the flight safety of the 787s.
The existing fuselage wrinkles might not compromise the flight safety of the 787s, but they will weigh and cost a lot more than planned because of the extra layers of carbon composite material. The added weight will reduce fuel efficiency for the entire lifetime of the airplane, which further increases the cost of use of these planes for the airlines that will be buying them. As for the permanent fix:
Boeing said tests had shown it needed to reinforce areas where the plane's wings join the fuselage.
You can bet this means all future 787s will weigh more than Boeing told their investors they would, which means some companies who slightly prefered 787s over an alternative by, say, Airbus, might also cancel their orders and buy from the competition instead.
I'd rather you rationally disagree than irrationally agree.
They did this for several reasons. The first was to break the unions. The second, and more important, was to help sales. Sadly, America has some of the best knowledge of composites and the RIGHT place for this was here, not elsewhere. At this time, all of the issues that Boeing has is with offshored items (Production for china has been a QUIET NIGHTMARE for Boeing; Many of the parts are of VERY low quality). In fairness, my Wife and a number of friends work for Boeing, so I do get to see info that is not in the main-stream press.
I prefer the "u" in honour as it seems to be missing these days.
It's wierd - I used to think IT projects were the only projects that were impossible to accurately estimate. A lot of PMs I run into at work seem to think a software project is the same as a construction project, but I think they're totally different. There is little change in the time it takes to pour a certain amount of concrete, run standard electrical for a commercial building, or other construction/product build tasks. In software-land, since everything's so fluid, it's anyone's guess how much time it'll take to fix some crazy bug, install hardware, debug a hardware or software installation, or write documentation. And even when a construction project over-runs its time, you pretty much know exactly how far off you are and how long until you're on track again.
Now this 787 project comes out and blows my assumptions away! Apparently you CAN overrun a construction or build project's time and budget just as easily as IT projects.
From what I've been reading, the fact that Boeing basically outsourced everything but final assembly of the plane to different contractors has come back to bite them. One of my IT specialties is integration work -- and I've worked on a lot of contracted software products that totally don't work when you get their individual parts back and mash them together.
Part of me really wants to gloat and say, "Ha ha, you listened to a bunch of retarded MBA consultants who convinced you that lean production and lowest-bidder subcontracting was the way to go!". BUT, I really can't. Boeing's in a lot of trouble if they can't pull off a major integration/rework effort right away. Airplanes are one of the last things the US actually makes and exports from a manufacturing perspective, so it's important that they just drop everything and figure out what's wrong. Airbus will be more than happy to sell A340s, A350s and A380s to all the waiting airlines.
But deep down, I still think those MBAs should have thought a little bit about how many thousands of parts and systems a typical plane has...
I live in the Pacific Northwest, where Boeing used to do most everything. There is a strong belief up here - maybe because we feel screwed by Boeing - that Boeing moved production all over the place basically to bust one of the few strong unions we've had up here in Washington. I'm not a big union guy; but having watched Boeing's management and their treatment of their workers over the last 20 years... that's one place where I think a union is called for. It wasn't that long ago they laid off thousands of workers because of a downturn, yet found it in their hears to give the top-tier management very large (20% or so, IIRC) pay raises at the same time.
I've had friends who worked for Boeing (engineers, mostly) over the past couple of decades. Most of them have gotten out. When they started, there was a lot of pride amongst the workers at the company. That all went away, at least in the groups my friends worked in. And I do believe that companies whose employees are proud of their work do a better job than those who've stopped caring because they feel upper management has stopped caring about the product.

The problems are with barrels that aren't even close to production yet. Boeing (in as much as you can believe them anymore) says that this will not delay the production of the 787 (to first flight) of the 787 any further than it already has been.
This information is out there, is it so difficult to go find it before publishing wrong info instead?

Oh yeah, and the problem with the sections isn't with the skin, it's with the stringers behind them. It leads to wrinkles in the skin, but the real fix is to not mess up the stringers in the first place.
The statement that this casts even more doubt on the outsourcing model set up at Boeing under Alan Mullaly is most definitely not diminished by the inaccuracies in the reporting of these details.

Flying in general is extremely safe.
Plus 53% of Aircraft crashes are caused by Pilot Error. A total of 67% are caused by "human factors" (e.g. Human Error, Sabotage, Maintenance mistakes etc). 11% by weather. Which leaves a 21% chance of mechanical problems.
Which tells me you should be a lot less concerned about who builds your aircraft and instead look at how well trained your pilot and the ground crew are. Because they are more than likely the ones who will get you killed.
PS - Plus Boeing aircraft have crashed over five times more than Airbus Aircraft (but are also much more popular, so reading the above it isn't surprising).
They should just do what we do in software. Slap a beta label on it and ship it out the door. Then act condescending when someone complains that their plane crashed.
With Boetox?
Russian planes fly with airlines worldwide. Just two examples:
Tu-154 http://en.wikipedia.org/wiki/Tupolev_Tu-154 "The aircraft has been exported and operated by about 17 non-Russian airlines, as well as a number of non-Russian airforces. It remains the standard airliner for domestic routes across Russia and other states of the former Soviet Union (CIS). The Tu-154 is one of the fastest civilian planes in operation (975 km/h) and has a range of 5280 km. Designed to handle unpaved and gravel airfields, it often operates in extreme Arctic conditions of Russia's northern territories."
(I've flown on it. Nice plane.) pics at airliners.net
The older Tu-134 "has seen long-term service with some 42 countries, with some European airlines having made very intense use of the 134 (as many as 12 takeoffs & landings per plane daily)." http://en.wikipedia.org/wiki/Tupolev_Tu-134

Accidents by aircraft type.
Fatalities by aircraft type.
The Boeing 737 NG, 757 and 767 have crashed more times then A330 and A340's. If we include older aircraft such as the B737 (Classic) and B747 vs the A320 and A300 we have the same story.
Airbus' highest fatality for a single aircraft type A300 - 1423 deaths.
Boeing's highest fatality for a single aircraft type B737 - 3990 deaths.
That being said, if you are boarding any type of aircraft you have already survived the most dangerous part of your journey, the drive to the airport.
Calling someone a "hater" only means you can not rationally rebut their argument.
There are ten times as many 737s as there are A300s so 3 times the number of fatalities is still 3 times safer.
As a mid-career aerodynamics engineer in the American aviation industry, the one trend that I wish I could reverse is the perception that "the process is the product", or that with suitable care and attention to composing Interface Control Documents (ICD's), that the actual act of doing detail design - of applying the lessons learned by a successful technology company over decades of tech and product development - is a fall out.
It seems to me that Boeing's touting its expertise as a "systems integrator" is a direct reflection of this attitude. You can only achieve the expertise in "systems integration" if you have learned the lessons by actually doing. For fifty years or so, this was accomplished in this industry naturally - young engineers would come start their careers doing basic work (designing clips and brackets, plotting data, composing reports under senior engineers' supervision). Do that long enough, and you gain enough experience to begin to know where issues may lie, and procedures to take to avoid them. Eventually, one could move into a position of seniority where you would be the one overseeing younger engineers, and directing them what and what not to do.
Nowadays, it seems that the staffs in Systems Engineering (or SEIT) have no practical experience whatsoever. They are given checklists, written by the last wave of experts prior to their golden parachute retirement party, that tell them the most basic questions to ask and the most basic data to be documented, but don't have the hard won knowledge required to push the issue when required. Too often, design reviews are reduced to a SEIT team making sure their document list is complete - and not bothering to check that the information contained in those documents are accurate or applicable.
Great book on the development of the 747, "Widebody", by Clive Irving. In it, he points to the fact that what enabled the 747 was a direct result of all that came before it in Boeing's experience - from a monocoque fuselage in the 247 (and the importance of doing wind tunnel testing - and engineering - in house lest the results be pinched by the competition), through the complicated systems on the B-29, to the swept wing and podded engines of the 707. And the players in the 747 development were instrumental in all of those previous projects. He stresses the "design bibles" that were compiled across the technical specialties at Boeing - paid for in some cases by pilot lives (Eddie Allen and others). During the days of competition with the USSR to develop an SST, those design bibles were guarded as if they were state secrets.
Fast forward to today - Boeing outsources not on a build-to-print basis (as you would to a subcontractor), but a total systems solution. They are trusting their subs to design primary structure and produce them - a situation unimaginable in the old days. Maybe they could get away with that approach once - but if you do pursue that path, after you do this once when do you learn and how do you teach the next generation for future design projects? You don't. Who will be available in your home organization to raise the bullshit flag when a low cost subcontractor promises something that is patently impossible? No one, at least no one with the background of experience and technical reputation to be able to stand up to management, badge on the table, saying this shit won't fly.
Unfortunately for Boeing, and the US, I feel they have already mortgaged their ability to pull off this outsourcing by bleeding their technical staff over the past decade or so. They will eventually pull the 787 program together, and it will eventually pull a profit - lack of competition will insure that - but the break even point on this program will continue to slip to the right, just as it did on the L-1011 and the DC-10, and you can see what those programs did to their respective companies.
Please stop spreading bullshit. Tn the history of aviation there are far more crashes caused by pilot error than caused by fly by wire. Also, flying Boeing is potentially much more fatal.
Let's compare the statistics for the A320 family and the Boeing 737 family - that's the airplane you are most likely to fly.
Of the 6000 delivered Boeing 734 planes there were 144 hull-loss accidents resulting in 3847 fatalities. Of the 3958 delivered A32x there were 20 hull-loss accidents with a total of 631 fatalities.
Yes, that's right. There are only 1.5 times more delivered Boeing 737 but they have a 5 times higher hull-loss accident rate a 6 times higher fatality rate. Correcting for the same number of machines there would be 4.8 times more hull-loss accidents and 4 times more fatalities at Boeing.
Maybe you should change your sitting location.
Ah, by the way, A32x is pure fly by wire.
