I wonder how much of this is true. If it is true and Boeing Management believe the 787 should not be grounded or are in denial then there is seriously something wrong at the top of the chain. Also Ive heard that Boeing has gone back to SPEECA, and its looking likely SPEECA will not sign and strike...seriously Boeing Execs you just love making the hole bigger and bigger, and right now all the attention is on you and your not getting any good publicity out of this so what makes you think a strike will do you any good.<br /><br />http://www.post-gazette.com/stories/business/news/boeing-leadership-unhappy-with-faa-dreamliner-decision-671459/Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7553457216067299334.post-48188001048247421692013-01-20T20:05:56.741-05:002013-01-20T20:05:56.741-05:00Looks like they're narrowing it down.

We better pray the investigation blames a bad batch or an assembly mistake by Boeing. <br /><br />If not, does anyone know if it would be possible to put another battery in the 787 that Boeing already uses in other models as a temporary replacement? If not and the investigation blames battery design this would be catastrophic to the program since Boeing would need to design a new battery and then go through months of rigorous testing of that one.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7553457216067299334.post-73458717797793284292013-01-19T21:34:04.614-05:002013-01-19T21:34:04.614-05:00Based off what I am reading the batteries were ope...<br />Based off what I am reading the batteries were operating at twice the design limit. <br /><br />Two questions:<br /><br />1) Shouldn't the batteries be designed and tested to operate at a higher voltage than normal operations. <br /><br />2) If the investigation shows that the operating the battery caused the malfunction should be a relatively simple fix I.e. incorporate a voltage meter and a breaker so that if the voltage comes close to what should be over the operational design the breaker would trip and shut off power to the battery or close the loop until the voltage decreases and then power would be restored to the battery. Also I have been thinking that quite possibly the airlines weren't properly charging the batteries so that when a plane was at the gate the battery would charge and once airborne the battery would still charge. If the batteries are only needed for starting of the APU an in case of an emergency there should be an option for pilots to take the batteries off the electrical system one the APU is started and a the switch would turn the batteries on incase they were needed. <br /><br /><br /><br /><br />This is just my two sense from what I have been reading. Anyone else have any ideas?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7553457216067299334.post-18096643286582874652013-01-19T16:40:02.403-05:002013-01-19T16:40:02.403-05:00IANAE, but I think any fix might be more involved ...IANAE, but I think any fix might be more involved than just redesigned batteries.<br /><br />There are at least three aspects to this: <br />1) To find and fix the issue itself.<br />2) To mitigate the effects of the fire if the fix fails and it happens again. <br />3) An investigation as to why these issues were not picked up in flight test or earlier (could be done after return to flight).<br /><br />Mitigation could be ensuring that if the battery catches fire, the fire does not spread (as it did not in these cases), and that the flammable electrolyte do not escape into other areas.<br /><br />Current best case? Probably that the batteries were manufactured incorrectly (making it a factory test issue), and mitigation alterations are something simple like improved battery unit casings.<br /><br />Worst case? At a guess, that it is a significant problem with the battery charging circuits that are not easy to fix, causing the FAA to lose confidence in the subsystem. Goodness knows what would happen then: would non lithium-ion batteries of the correct capacity even fit?<br /><br />Let's hope the problem's found, reproduced, fixes developed and implemented soon, so the beauties can regain the air.David Cottonhttps://www.blogger.com/profile/17662508558674678268noreply@blogger.comtag:blogger.com,1999:blog-7553457216067299334.post-70296602469439429922013-01-19T11:17:42.226-05:002013-01-19T11:17:42.226-05:00At least they are reporting it is not the electric...At least they are reporting it is not the electrical system but the batteries, so it is not like they have to redo all the electrical systems, they just need to redesign the batteries and make new ones, test them, give them to the carriers and stick with the good design and implement this process ASAP.<br /><br />On a good note: "The Boeing 787 is the nicest plane I've ever flown" - Capt.
