FAA Grounds 787 with Emergency Airworthiness Directive
The Federal Aviation Administration has ordered the U.S. fleet of Boeing 787 planes to be grounded, citing an incident in Japan earlier today in which one of the jet's batteries emitted smoke. The Japanese report came a week after a similar incident occurred in Boston. (www.npr.org) Más...Sort type: [Top] [Newest]
To me it seems that due to misplaced anxiety , both , Airbus and Boeing engineers and managers side tracked the basic rules of professional propriety taught in the respective class rooms ! And hence the problems in their star projects , A380 and B787 . Both committed professional blunders in the haste of out smarting each other . An utterly futile strategy . Both have their own well defined segments . I hope better sense will prevail on both and they will revert to age old principles of professionalism giving due thoughts to the sensitivity and the safety involved into the highly vulnerable product/service .
I am a bit confused about this statement:"The battery, used to start a small turbine engine that provides power when the plane is parked, is designed to not burn critical wiring or the plane’s structure, Mike Sinnett, the 787 chief project engineer, said in a press briefing last week."
Li-Ion run-away battery chain reactions can get very hot, emitting flames up to 1000°F (or more). I have no idea the structure of this particular cell or pack, but can imagine it has multiple cells. With the use of so much composite material, I find it hard to believe there is any capacity to contain such heat.

Yes you are very right I posted several times about those batterys. They are something to see go up too. See youtube about the model airplane battery fires even in flight. This is a known fact and has been for years in the model airplane community. Also full scale AC have been lost due to freight inflight fires.
The battery itself is SUPPOSED to be designed for this not to happen, hence the emergency AD.
I think there was a directive a year or two ago that had issues with the transport of Lithium-ion batteries because of overheating issues (my lap is hot right now from my li-ion battery). If that is so, why does the NTSB, FAA allow / and or Boeing for that matter equip a plane with li-ion technology batteries as standard equipment for a power source. No doubt those babies are getting overheated with the electronics suite on those planes. Hope this gets worked out without any tragedies. A nice plane for the future. But get those batteries out of there. TOO HOT..
I learned the hard way about brand new products. We booked a cruise a few years ago that was the maiden voyage for the particular ship. Despite all of the pre-cruise publicity, our week was terrible. Our departure was delayed 6 hours because the Coast Guard would not certify the ship's seaworthiness while several safety systems were unfinished. Once we were under way, the ship rolled uncomfortably from side to side because the port stabilizer would not deploy. The air conditioning didn't work for the first 3 days, so we had to leave our balcony door open for cool air. Some of the ovens didn't work, so very few hot items were available for days. The list of problems grew longer each day. For the most part, the passengers took it in stride. At the third port of call, one of the couples at our table had "Voyage of the Damned" t-shirts made for all of us. The cruise line had a dozen engineers join the ship. They worked tirelessly until almost everything was fixed. The cruise line issued vouchers for a 75% discount and a cabin upgrade on a future cruise. Although everything turned out well, we have decided not to schedule a trip on a ship until its 3rd or 4th month in service.
The 787 is a revolutionary aircraft, so some problems were bound to pop up (although I doubt anyone would have expected them to be this bad). Luckily, nobody has been killed or injured in any of the incidents. Thankfully, the aviation world has learned its lesson from the Comet and DC-10 accidents. Boeing will find a solution and the Dreamliner will eventually turn out to be the great plane that everyone expects it to be. Boeing will make it up to the airlines in some way. I just hope the airlines are fair in their treatment of passengers. I'm sure many of them bought tickets with the expectation of flying on the 787. At the very least, changes and cancellations should be permitted without the usual penalties.

Drat. I *knew* this would happen right before I'm scheduled to fly the 787 ORD>IAH next week. The whole point of the trip was to fly the 787. Now I guess it will be with a 763 or whatever. Grr-rrrr.
