A Week Boeing Would Like To Forget
By Alex Zolbert, CNN, updated 2:01 PM EST, Thu January 10, 2013
More concerns for Dreamliner - (CNN) -- Some passengers pay no
attention to what type of airplane they'll be flying on. Others are
obsessed.
I'd put myself in the middle of the pack, mainly due to the new planes
on offer from Airbus and Boeing.
So I was in slightly better spirits this week, as I boarded the 11-
hour United Airlines flight from Los Angeles to Tokyo this week.
It was my first chance to fly on a Boeing 787 Dreamliner.
But the trip quickly descended into -- certainly not a nightmare --
but definitely a headache.
Dreamliner catches fire at airport
It's a drill millions of travelers know all too well.
After starting the taxi out to the runway Monday morning, we were
informed that there was an issue with the computer system, and they
were unable to start one of the plane's engines. We remained onboard
for nearly 3 hours, as flight attendants sheepishly offered cups of
water to frustrated passengers.
Eventually we disembarked.
A delay of four hours turned into five, then six, seven ... and the
flight was eventually canceled.
We then had the pleasure of spending the night at an airport hotel
that seemed to have been last updated around the time commercial air
travel started.
It was then that I realized we weren't the only ones encountering
issues with the Dreamliner on Monday.
A Japan Airlines' 787 caught fire in Boston after passengers
disembarked.
Boeing said the fire was traced to a battery unit that helps to power
electrical systems when the engines are idle -- typically while a
plane is being serviced or cleaned. And the company says it's
cooperating with investigators.
As Tuesday morning arrived, we were back on board another United
Airlines' Dreamliner in Los Angeles.
But in a rather comical turn of events, the second plane never left
the gate.
We were told there was an issue with the paperwork filed with the FAA.
More than a day late, many coffees, and very little sleep later, the
third time finally proved to be the charm -- more than 24 hours after
our scheduled departure.
But as we finally took to the skies, more Dreamliner issues were
unfolding.
Another Japan Airlines' 787 in Boston had to scrap a takeoff on
Tuesday due to a fuel leak. And an ANA Dreamliner flight was canceled
in Japan on Wednesday, because of a glitch with its brake system.
But Boeing is standing by its latest aircraft. The company's chief
project engineer, Mike Sinnett, says he is "100% convinced the
airplane is safe to fly."
Analysts seem not to be alarmed, saying that new aircraft models often
have "growing pains."
But what is very clear is this was a week that Boeing would certainly
like to forget.
After a nearly 40-hour trip back home, I'll second that.

The batteries are obviously being overcharged..a system problem.
To fix the problem and have the recertifications will take time..and
BIG dollars until the plane files again.
I suspect it is a failure to properly oversee system integration
within Boeing.
And where there is smoke there is fire...if the electrical system has
not been properly reviewed it is a KEY signal that there are other
similar oversights.
Bottom line..if I were actively flying I would NOT fly the 787 for
years...let someone else be the lab rat.

Strictly speaking, the 787 is not an engineering failure.
Like anything complex and new it has a few issues. So far
these issues haven't caused any fatalities.
Now from a business point of view however ... the plane
may indeed be a failure. It's already got a bad reputation.
As problems with aircraft CAN be fatal, passengers seem
reluctant to fly on them - envisioning themselves burning
to death as they plummet from the skies.
If enough people won't fly on a 787 then there's no point
in airlines HAVING 787s ... and orders will start to be
cancelled. Boeing put a LOT of its money and reputation
on the line with this plane and - oversold its fantastic
wonderfullness - and this could be quite a disaster for
that company and the vast number of employees and
subcontractors involved.
So, I'm gonna offer an idea ... withdraw the aircraft
at once and refund all payments and pre-payments.
Yes, this IS severe ... but there's a part two involved ...
In a year or two, offer a "797" ... which will be
essentially the fixed-up debugged 787 with just
enough cosmetic differences so it'll seem like a
"new" model. This way Boeing gets to use 99% of
the money it spent on R&D - ie it doesn't have to
throw away the 787, just the name.
Furthermore, offer the '797' first in a CARGO variant
and let it rack up a shitload of time in this less
critical kind of service to prove its a worthy craft.
A year later, THEN offer the passenger version - with
its "Proven Perfomance" airframe.
Yes, it'll set Boeing back ... but it'll save it from
destruction. Better late profits than NO profits.
OR ... they can just dissolve the company now and merge
its remaining assets with Airbus. Easier, but not, IMHO,
really the best way to go.

Heat and cold.
On an electric vehicle, getting the battery too cold will (not
can) result in a degrading of the performance of the cells. The
fix is adding an "Electric Blanket" to keep the battery warm (not
hot). The residual power required by the blanket is negligible.
You get back much more than you lose.
Heat. I can see problems with the Lipo batteries. The battery
they chose is one that is not on the list of Vehicle safe
batteries. It is the best, the highest output but with it comes
problems. Lithium cobalt oxide (LCO), for vehicles, is listed as
unstable compared to the rest. It's very suspeptable to heat.
And sitting on the ground running up on a hot day, the battery
compartment will sky rocket in heat. The safest to use is the
lead acid but it's very short lived in this application. To use
any Lipo battery, it requires a cooling and a heating system to
keep the battery at an optimal temperature. The LCO is just the
worst of the lot for overrunning (catching fire, generating
Oxygen when it burns) than any other Lipo battery.
The Fix? Get rid of the LCO and temperature control the battery
compartment. Even a Lead Acid doesn't like excessive cold or
heat. But it won't turn into a major oxygen fire. Sometimes,
newer isn't better. But the various other Lipo batteries are
safer than the LCO which has a proven track record of burning.
BTW, the LCO isn't the cheapest by far. The LipoMG battery is
the cheapest but it has a low service charge rate. The Lipo4 has
a decent service rate and is what is primarily used in various
vehicle applications. But, maybe, the old Lead Acids may be the
way to go on this one. They are the most stable and the most
safe if you keep them in a wide range of temperatures.
Newer isn't always better.

So, Obama:

2) Gave the UAW and GM execs billions of dollars.
3) Cheated those holding GM bonds out of their money to increase what the

It did not acquire the REPUTATION for being
dangerous.
That's all-important.
That's all that counts.
The 787 is *done*.

Or maybe you're trying to say, the APU is simple, so the solution will be
simple.
Either way, you're ignoring the complexity of the entire electrical
system. Which kinda makes you claims absurd meaningless and laughable
prattle.
You sound good, tho'. Keep pontificating! Maybe you'll fool someone into
thinking you know something.
So, how many days has it been? Where is that simple tweek!?

with heavier old tech batteries. The charging system will be fixed -
and you will be safe to bet it will be a "relatively minor tweek" to
the system. It will not be a total re-design of the APU system. The
batteries do not overheat if they are not abused. The charge control
system is abusing the battery, causing it to overheat. They may need
to redisign the battery pack to add cooling to prevent damage IF they
overheat - but the first thing is to fix the charging system so they
do NOT overheat.
I also question why they used lithium Cobalt batteries - slightly
higher energy density than the safer Lithium Iron Phosphate or Lithium
Nickel Manganese Cobalt Oxide batteries, at the expense of a higher
danger of thermal run-away. Perhaps a change to one or the other of
these chemistries instead of the Lithium Cobalts will be required as
well.

aircraft with aluminum structure. The 787 has a lot of high strength
composite, but aluminum is still a structural component. The 2
materials do not peaceably co-exist - in case of a leak there are
risks - which have been managed so far with Ni-Cads in aircraft use -
but they are NOT benign. NiCad and NimH both ose pottassium Hydroxide.
They are also not immune to overheating - they just boil the
Pottassium Hydroxide out, damaging the plane instead of burning. Not
quite as serious, in the short term - but perhaps just as damaging in
the long term?
In my opinion, going back to NiCad or Nimh would be a big step
backwards - as well as requiring a complete recertification of the
system.

Just because the tweek will be minor does not mean figuring it out
will be simple. And getting it signed off will not be a simple matter
either - we ARE dealing with certified aircraft.
I suspect there will be some reprogramming of the charging system and
a possible switch to Lithium Iron Phosphate (LiPo ) cells from the LCo
(Lithium Cobalt Oxide) batteries that caused a lot of consternation in
portable devices, like laptops, a few years ago. I cannot understand
why LCo batteries were spec'ed instead of LIPo or LNMC cells. The
relatively minor power density advantage is hard to balance against
the known issues with LCO cells. The LCO cells CAN be safely used
with proper controls - but the risk is still there.

help in terms of public *perception* ? If the public
thinks it's a deathtrap then why would airlines buy
any ? Switch to Airbus instead.
Remember Value-Jet ? Remember the flaming CRASH ?
The *name* 'Value-Jet' became inviable - and they
had to change it to "Jet-Blue".
I don't think Boeing can try that trick.
Recall the planes, spend a year REALLY debugging
them ... then re-issue them as the '797' instead.
Tweak the cosmetics a bit too ... then it will
*seem* like a new plane and public paranoia will
be avoided. Yea, it'll be 99.5 percent the 787,
but *perception* is what's gonna count.
BTW ... it wasn't actually the batteries. Something
in the charge/charge-regulatation electronics. If
someone else made it, Boeing can blame 'em. If not
then it's a black mark against Boeing.
Given the volume of problems in such a short time,
hey, didn't Boeing TEST the damned planes ? Short
answer - no ... not enough. They were behind in
delivery and decided to test 'em with live human
guinea-pigs.
Ya didn't see the CEO or board members flying on

that's a lot! The fact people buy tickets based on the cheapest online

Public PERCEPTION matters. That perception is immune
to reason, to evidence, to statistics. It's a emotion
thing.
And Boeing didn't spin fast enough to prevent the

that monitors and controls the charge state. Could
be rather minor - and under-rated low-ohm resistor,
a cheapo Chinese cap or inductor ... or it could be
further up, in the software.
In the first case it means that EVERYTHING that uses
similar components, and/or was designed by the same
engineers, has to be taken apart and torture-tested.
In the second case ... COULD be a local firmware
glitch - assuming they're using "smart" modules -
or it COULD be in the system software. The former
is less of a big deal - such control programs tend
to be relatively short. If the system software
is nanny to this and more components however ....

This is one of those cases where capitalism works
against us. The competitors tend to rush these very
complex machines out the door, trying to stay ahead
of each other. A modern airliner is at least as
complex as a space shuttle ... and they always had
problems with those (usually with tri/quad redundancy
to save their asses).
IMHO, especially given the disaster possibilities,
airliner manufacturers should NOT be using the
public as their beta testers to "work out the
kinks". The planes should be READY before the
first passenger buys a ticket. There needs to
be more regs and govt oversight.
(does that sound ultraright-wing ? :-)

The point is, within any *given* mode of transportation, people don't
want to use dangerous vehicles if they have a choice, /ceteris paribus/.
If the 787 is dangerous and a 777 isn't, people will want to fly on

All the warnings were NOT there, and the ones they had were
misleading. The stall indicator shut off below a minimum airspeed and
came on when they correctly put the nose down and gained speed. The
stalled plane remained fairly level and controllable in pitch as it
fell at a very low forward airspeed, a condition the FCS apparently
didn't understand. Roll control was harder and kept them occupied.
They advanced the throttles to TakeOff/Go-Around power and kept the
nose slightly high, which SHOULD have been the proper procedure if
they'd had more airspeed. At night in a storm they were purely on IFR,
with no visual cues and airspeed indicators that had been and could
still be(?) reading low only because they had iced up.

hyper-nationalistic and sensitive about being an untraveled rube.
I haven't seen anything to suggest Europeans are "crucifying" [sic]
Boeing over the battery problem. You seem to be trying to downplay it.
It's a serious problem, and it has led to the *American* FAA grounding
all the planes. While ice in the pitot tubes is suspected of producing
the faulty airspeed readings, the main cause of the crash of the Air
France A330 was pilot error. They might conceivably have safely flown
the plane either back to Brazil or on to France. By contrast, if a
battery fire in a 787 ever spread, the plane most likely would crash.
The battery problem is serious and needs to be corrected, and not
pooh-poohed by insanely nationalistic Americans who stupidly read too
much into a Boeing-Airbus competition. Also...Americans need to get out
of their general provincialism.

that caused it to burn fuel faster than expected. The crew used a
flight management system that estimated how far they could go on the
remaining fuel, but that system did not take into account the effect of
increased drag, so they ran out even earlier than anticipated and had to
glide the aircraft toward an airport, which they didn't reach by 500 meters.
Get your facts straight next time.

Sixth NTSB update:
|
| January 29
|
| WASHINGTON - The National Transportation Safety Board today
| released the sixth update on its investigation into the
| Jan. 7 fire aboard a Japan Airlines Boeing 787 at Logan
| International Airport in Boston.
|
| The examination of the damaged battery continues. The work
| has transitioned from macroscopic to microscopic
| examinations and into chemical and elemental analysis of
| the areas of internal short circuiting and thermal damage.
|
| Examination and testing of the exemplar battery from the
| JAL airplane has begun at the Carderock Division of the
| Naval Surface Warfare Center laboratories. Detailed
| examinations will be looking for signs of in-service damage
| and manufacturing defects. The test program will include
| mechanical and electrical tests to determine the
| performance of the battery, and to uncover signs of any
| degradation in expected performance.
|
| As a party contributing to the investigation, Boeing is
| providing pertinent fleet information, which will help
| investigators understand the operating history of
| lithium-ion batteries on those airplanes.
|
| An investigative group continued to interpret data from the
| two digital flight data recorders on the aircraft, and is
| examining recorded signals to determine if they might yield
| additional information about the performance of the battery
| and the operation of the charging system.
|
| In addition to the activities in Washington, investigators
| are continuing their work in Seattle and Japan.
|
| Additional information on the NTSB's investigation of the
| Japan Airlines B-787 battery fire in Boston is available at
| http://go.usa.gov/4K4J.
|
| The NTSB will provide another factual update on Friday,

I finally found it on page 44 of the main body of the BEA inquest:

"............If the CAS measurements for
the three ADR are lower than 60 kt, the angle of attack values of the
three ADR are
invalid and the stall warning is then inoperative. This results from a
logic stating that
the airflow must be sufficient to ensure a valid measurement by the
angle of attack
sensors, especially to prevent spurious warnings."
The stall warning and pitch attitude graphs are on page 6 of appendix
3.

Boeing has far too much invested in the 787 to walk away; it
would be the end of the company. The FAA and the Feds in
general have no interest in seeing one of America's biggest

A friend of mine was a 300 series training officer for a major airline
and said if the pilot had a pulse and a brain there was no reason for
the plane to crash. The GPS was still functioning, giving them an
indication of ground speed and altitude. Ground speed and air speed
are not the same - obviously, but they could still figure out they
were flying too slow. Stormscope told them what kind of storm
conditions they were getting into as well - no excuse for it.

flying anywhere CLOSE to 60 kt. Minimum landing soeed is over twice
that speed EMPTY. And it goes up the heavier the plane is.
It is virtually impossible to "stall" a functioning A3X plane - it
will just descend like an elevator, under full control. The GPS will
show a rapid rate of descent even when the static port is totally
blocked.

And yet they did stall it, at extreme altitude in "coffin corner", and
then fell flat with an indicated forward airspeed below the 60kt
threshold until they pitched down, which triggered the stall warning
for the wrong reason. The altimeter tape showed them that they were
falling, but not why.
Now they know and that particular accident is extremely unlikely to

Honestly though, if there were ever any doubt about Airbus landing
gear from that incident, it may have been either helped or hurt later,
on September 21, 2005, by the A320 that had to go back to LAX and land
after its nose wheel was accidentally at a 90 degree turn. (it looked
scary when it was trying to land)

It *was* mainly pilot error, you stupid drooling fat fuck. By saying

"Its [sic] like it just ran out of fuel and fell out of the sky or
something", you suggested it was something else.
It was only partly pilot error. They relied on a "Flight Management
System" tool to estimate fuel consumption, but the program didn't take
drag into account and so gave an invalid figure.

Yeah..I saw that article.
This will NOT be any quick fix.
Anybody hear how much this has cost Boeing and the airlines so far?
It would be in the millions and counting.

No, because no one has died in that Boeing 787 plane yet, like with
another Airbus plane.
Another fatal crash landing killed a person or so, I think, here in
this video of an Airbus A319 (which came out only a little before this
incident).
