Japan Grounds Fleet of Boeing 787s After Emergency Landing
hcs_$reboot writes "The Boeing 787 Dreamliner has already occupied some of Slashdot news space recently: FAA to investigate the 787 (Jan 11) or 787 catches fire in Boston (Jan 08). Today (Jan 16 JST) another incident happened that led to Japan grounding its entire 787 fleet until an internal investigation gives more information about the problem. A 787 from ANA had a battery problem and smoke was detected in the electronics. The plane had to make an emergency landing and passengers were evacuated. "
Why, just last week Boeing told us the safety concerns were a non-issue!
I swear to God...I swear to God! That is NOT how you treat your human!

Will not a fire light it up like a briquette?
Yeah yeah, it's "compressed graphite", or whatever the euphemism is for the material.
How many times have you seen a diamond burn without immersing it in pure oxygen? It's just compressed graphite, after all.
The correct joke should have been: Boeing should reconsider using Sony batteries in their planes.
Is it just my observation, or are there way too many stupid people in the world?
I flew the 787 from Haneda to Frankfurt two weeks ago, and am happy to report the flight was excellent and as far as I can tell I wasn't killed in a fire.
Are you really this dumb or are you just pretending?

That word doesn't exist as much as you think it does.

It appears that the bigger danger in a crash (to both the rescue workers and any survivors) is inhaling carbon fibers:
http://www.netcomposites.com/news/dangers-of-carbon-fibre-debris-from-aircraft-crashes-exposed/3306
Research at Farnborough in the 1990's indicated that if carbon fibre composite material is shattered in the absence of fire there will be little or no release of respirable fibres. If you burn carbon fibre composite material without subjecting it to high energy impact there will be little or no release of respirable fibres. However, if you subject carbon fibre composite material to high energy impact while simultaneously burning it with a high temperature flame - typically 1000C (typical aircraft crash conditions) significant quantities of respirable fibres may be released
I've always found it best to keep the smoke in the electronics. It's when it gets out that you have problems.
I've read that Boeing was intent on outsourcing as much of the design as possible, and even had a catch-phrase: "the product is the process". I've read that in order to clean up the design, they needed to bring in more Boeing engineers. I wonder what extent this is true, and how much of their plane was designed by third parties? With engineering, it's always hardest to get that last fraction of a percent nailed and verified; an exponential more effort for that last few percentage points. I have a friend that designed electronics for aircraft, and understand that the cables, connectors, and electronics are subject to a very high standard for robustness, I find it rather shocking to hear that there was a fire. I wonder what kind of technical over-sight did they do with their contractors and their own engineers. I've always considered that Boeing was over-the-top with this sort of thing. This is a cautionary tale for anyone that wants to outsource. How do you guarantee that your subcontractor has done a sufficient job? That subcontractor does not necessarily want to let you in on all of the engineering details so they can avoid being designed out. Assuming that they were given everything, I wonder if they had their own engineers review them. I understand that if you print out the number of individual components in a modern fighter aircraft as a function of time, it would be linear on a log scale, meaning that the number of all components have grown exponentially. As subsystems become more complicated, they are increasingly designed by small teams of specialists. Outsourcing has it's merits. It's hard to be a generalist.
That's where it's supposed to be. Only when it comes out is there a problem.

Poor America, can't make planes like the Europeans. The A380's have had a few problems but not as many in such a small time.
So put a filter in the oxygen mask that drops down in an emergency?
Yeah, the DeHaviland Comet airliner was a sterling example of the quality of European aircraft design...
There is no God, and Dirac is his prophet.
....or has things like this been happening since Boeing moved their headquarters from Seattle to Chicago?
That this is the first aircraft Boeing built that uses outsourced production...
I know the TSA has been doing cavity searches for a long time. But exacuating passengers seems both extreme, and dirty. Shouldn't the world health organization have something to say about this?
Maybe next time there's an emergency landing, they should consider evacuating the plane, instead of the passengers. Besides, if it's a rough landing, some of the passengers are likely to self-evacuate.
While your statement might be technically correct (A380 has been in service longer, so not "such a small time"), there was that whole "sometimes the engine explodes in flight and damages the plane" thing. That probably counts as a fairly serious issue.

Ah, you must mean the first ever commercial jet airliner; which was of course not American. The whole industry learnt lessons from microfractures in stress points in the new aluminium airframes, and after the windows were redesigned it managed to get 30 years of service.
So what's the US excuse now? Forgot how to build, did we?
"Small time" refers to the 5+ incidents in the past two weeks.
Also, the engine you cite is from Rolls Royce, not Airbus. Boeing uses Rolls Royce engines in a number of its planes as well, and you'll note that none of the recent incidents with the 787 are traceable to the engine. They're aircraft problems, not power plant problems.
With internet connection it is much more handy to short Boeing stock on the first whiff of smoke.
this energy density is not safe for flight, folks. you can't get out and wait at the side of the road for the fire to stop, like you can if your hybrid car starts arcing and smoking.
if this is supposed to be a new economy, how come they still want my old fashioned money?
Well, if there is so much fire, there will be lots of poisonous stuff in the air regardless of carbon fibers or not. Firemen use breathers because of these toxic fumes, not because of a lack of O2, primarily. So, does it matter ?

That was an ENGLISH plane. But yeah, they tried to crash an A380 by means of engine explosion.
..the local Boeing $hill ??

Ahhhhh... the urban myth of the intrinsically superior quality of American aircraft. The Luftwaffe lost 61 Lockheed Starfighters in one year of operations, mostly because the thing was a proper bitch to fly. Eventually they lost 110 pilots and 270 Starfighters to accidents, that's 30% of the operational force. There used to be a joke that if you waited long enough, just about every square mile of Germany would have a Starfighter wreck in it. Your turn... (Allow me to suggest the AV-8B Harrier in USMC service)
"If it's Boeing, I ain't going..."
I had a dream, bright and carefree, but now there's doubt and gravity
I was referring more to the way it kept disintegrating in flight, but whatever...
There is no God, and Dirac is his prophet.
So was I. I guess that was lost on you, too.
I had worked as an engineer for approximately 30 years. What I have witnessed has disturbed me.
In the last 10 to 15 years, design decisions that used to be made by engineers have been replaced by cost accountants restricting most decisions of a technical nature and replacing it with "most cost effective solution".
I did some consulting for a small aero engines company about 15 years ago that had a brilliant concept dreamed up by a non-technical MBA executive to start building aero engines for small aircraft based on race car engines. Reasoning for that is because they are high performance engines. Well d'ohhh that is not what you want in an aero engine, you want reliability & safety as the most important factors. Race car engines need to be rebuilt after every race. Not a desirable attribute for an aero engine.
Needless to say extensive testing which I was involved with proved that this idea was half baked and it failed. Problem was executive management freaked and were cursing the engineers for destroying their "brilliant idea" and acted in a savage manner to the staff by trashing many of them.
In many aerospace companies, I have had been involved with have pushed out most experienced staff in favour of young and cheap staff. If I was to guess, I suspect Boeing has done the same thing. I have heard from many experienced colleagues that old technical problems that were resolved decades ago in the aerospace industry are re-emerging due to in-experienced staff and loss of knowledge.
This shift I suspect contributes in part to many of the issues being experienced in the Dreamliner.
my two cents
Yeah, the DeHaviland Comet airliner was a sterling example of the quality of European aircraft design...
Yes it was considering it was the first jetliner. Someone had to go first and it certainly wasn't the US because they were so far behind.
That was an ENGLISH plane. But yeah, they tried to crash an A380 by means of engine explosion.
...and the aircraft survived. That fact would actually motivate me to get on an A380 rather than the reverse. The advantage of really big aircraft is that they can soak up more damage than their little brothers.
The damage, in case anybody is interested:

I don't really get why they did not use bigger generator turbines instead of the batteries. Proven, lightweight technology. Smells like "batteries are cool; i have those in my telephone" marketing gimmick.
Maybe they will do just that in the near future - rip out the batteries and add a generator.
I think companies have had more than half a century to perfect airplanes and we still can't get windshields to not crack. It's time to transfer airplane manufacturing to private enterprise, preferably run by Elon Musk. Since he will colonize the universe in ships that will have to be 100.0% reliable for millions of years, clearly a piddling little toy like a 787 should be easy, maybe even just 3D print the whole thing out of neutronium (these cartridges are usually next to the Whole Periodic Table cartridges at the Staples).
(Can you spot the satire, sarcasm and mockery?)
The same is being said by many experienced software developers. Corporate knowledge is lost by management muppets who consciously Dumb Down decision making.
Instead of engaging their technical experts in to the dialogue "I have idea X, what are the problems, what are the technology solutions to the problems your mentioned, what can we do ?", they apparently think their MBA pseudo-science is above everything else. They do think communication should be linear top->down.
It seems modern managers have become incredibly shallow, intellectually. These people have a strong disgusted feeling for anything for the words "master", "expert", "veteran". They no longer understand that well-working technology is being made by seasoned, middle-aged to near-retirement-aged "masters" who have devoted themselves to some particular field. These are "masters" in the true meaning of the word, not in the "M-BA" meaning of it.
I am currently sitting next to a guy who is currently doing his MBA, I have more than ten years of R&D und my belt and I tried to educate this youngster about the virtues of the command line. "It's more productive if operated by the master". "It's more precise". "Less faults". "Mechanization".
Guess what "but I like those simple GUIs". Again, my thesis is that these people have intellectual shallowness, disinterest and disrespect of experts hammered into their minds.
you have to wonder if Boeing brought McDonnell Douglas back from the dead to make them.
Everyone knows there is *supposed* to be smoke in the electronics. It's letting the smoke *out* that causes problems.

I have a very good friend that worked for one of these sub-contractors in Rockford, IL. Heâ(TM)s a brilliant engineer. He told me about the enomous pressure Boeing put on them to complete their work by their deadline. Boeing constantly threatened the sub-contractor with fines. He spent many, many months working 70-80 hour weeks. Getting called into 2am meetings. Careers flamed out because of the stress. Substance abuse ran rampant. Families suffered. I hope no one gets hurt or killed flying on the 787. I hope the shareholders get handed a big bill to remedy the teething issues plaguing what was once a promising breakthrough design.
Have gnu, will travel.
787 engines on the other hand don't need an explosion to self-destuct.
Not if you define recent as the last two weeks, where the problems have really escalated. But there have been two engine incidents in the last 8 months, as well as one incident involving the same engine on a 747-800.
Yawn cant you make up something original? Boring, reeks of that asshole APK.
I suggest you look at the Airbus announcements made with respect to the wing cracks. I'm guessing that the cost to Boeing to fix the battery packs on the existing fleet and those on the manufacturing line will be significantly less that the cost to Airbus to fix all the wing cracks in the existing fleet and the retrofit those in production. The first A380 to actually have the wing crack issue properly fixed are not due of the production line until late 2014.
On a side issue - the failure rate of Rolls Royce Trent family engines is much much higher than it should be. That's what caused the Qantas A380 incident. The failure rate of those engines on A330's is concerning.
Bottom line - none of these manufacturers are perfect. But they all have a clear motivation to make the best aircraft they can - albeit to a price.
Every plane and every engine has issues. The point is that the relevant comparison of the A380 and the 787, if you really have your heart set on making one, is aircraft to aircraft, power plant to power plant. A defective turbine component in a Rolls Royce engine has no bearing on the work of the Airbus engineers, nor does the GE shaft failure problem of the engines you not have any bearing on the 787's current spate of kinks.
care to say that without "Post Anonymously" checked?
The DeHaviland Comet was actually a more important milestone in aircraft development for another reason.
The Comet had square windows in which the corners acted as stress risers and thus crack initiation points in the outside skin of the plane. The cracks grew due to metal fatigue mechanism which was not such a well understood phenomenon at the time.
There is a reason why windows on plane have rounded corners for the windows.
