*Passengers are convinced the 787 is a death-trap. That's ALL it takes to destroy it. 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). -- https://www.youtube.com/watch?v=1fh8-qJqMX4 |

NTSB 7th update
Synopsis: Navy research, no result. DoE rep has been added to the investigation. NTSB going to France to get Thales' take on the question. First update with *no next scheduled update*! Full text: | | NTSB issues seventh update on JAL Boeing 787 battery fire | investigation | | February 1 | | WASHINGTON - The National Transportation Safety Board today | released the seventh update on its investigation into the | Jan. 7 fire aboard a Japan Airlines Boeing 787 at Logan | International Airport in Boston. | | The auxiliary power unit battery, manufactured by GS Yuasa, | was the original battery delivered with the airplane on | December 20, 2012. It is comprised of eight individual | cells. All eight cells came from the same manufacturing lot | in July 2012. The battery was assembled in September 2012 | and installed on the aircraft on October 15, 2012. It was | first charged on October 19, 2012. | | Examination and testing of an exemplar battery got underway | earlier this week at the Carderock Division of the Naval | Surface Warfare Center laboratories in West Bethesda, MD. | The tests consisted of electrical measurements, mass | measurements, and infrared thermal imaging of each cell, | with no anomalies noted. The cells are currently undergoing | CT scanning to examine their internal condition. In | addition, on Thursday, a battery expert from the Department | of Energy joined the investigative team to lend his | expertise to the ongoing testing and validation work. | | NTSB investigators were made aware of reports of prior | battery replacements on aircraft in the 787 fleet, early in | the investigation. As reported Tuesday, Boeing, a party to | the investigation, is providing pertinent fleet information | which investigators will review to determine if there is | any relevance to the JAL investigation. | | 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. | | Next week, the NTSB battery testing team will initiate a | non-invasive "soft short" test of all cells of the exemplar | battery. This test will reveal the presence of any high | resistance, small or "soft" shorts within a cell. Also, an | NTSB investigator will travel to France with the battery | contactor from the JAL event battery, for examination at | the manufacturer. The battery contactor connects a wiring | bundle from the airplane to the battery. | | Investigators are continuing their work in Washington and | Japan and the team in Seattle continues to observe the | FAA-led review of the certification process for the 787 | battery system. The flow of information from these | observations helps to inform NTSB investigative activity in | the US and around the world. | http://www.ntsb.gov/news/2013/130201b.html --bks |

Boeing blows smoke:
| ... | We now have hundreds of people at Boeing, some of our best | and brightest, dedicated exclusively to solving this issue. | In addition, we've tapped into the pool of Technical | Fellows at Boeing, which offers deep knowledge across | diverse technical areas. These individuals achieve this | coveted designation after demonstrating expertise | recognized by leaders in Boeing, as well as across the | industry. | | We've also reached out to a handful of retired experts. | Seven retired executives and technology leaders make up our | Senior Advisory Group, which provides valuable | experience-based perspective and counsel to teams designing | and manufacturing. Together they have more than 230 years | of collective Boeing experience and have been awarded a | total of 46 industry awards and accolades. | ... http://boeingblogs.com/randy/archives/2013/02/when_the_going_gets_tough_boei.html Seven retired executives?

They must be joking. Your reading comprehension not too good, or your attention span REALLY short. You forgot the "and technology leaders" Is Boeing short of executives and "technology leaders"? They're paying CEO McNerney $22,000,000/year. At that price he should be able to figure out what's wrong with the battery all by himself. --bks |
