Just as an avalanche of events occurred this month related to the Boeing Dreamliner 787, with one issue after another rearing its ugly head, a seeming chain reaction of investigations has also resulted.
Boeing, the National Transportation Safety Board (NTSB), Federal Aviation Administration, Japan’s Transport Ministry and Civil Aviation Bureau launched investigations; and, the European Aviation Safety Agency (EASA) and the Directorate General of Civil Aviation (DGCA) in India and in Chile have also voiced concerns.
Aircraft safety officials in the U.S. and Japan took their examinations to GS Yuasa Corp. in Koyoto, Japan—manufacturer of batteries for the Boeing 787 Dreamliner.
Aerospace geeks everywhere were proud to see NASA step up to offer assistance. News soon surfaced, however, that GS Yuasa’s batteries are on the International Space Station (ISS). GS Yuasa President Bill Moll described the ISS battery replacement project as “one of the largest single deployments of lithium-ion cells in a space application.”
GS Yuasa Lithium Power Inc., under contract with Pratt & Whitney Rocketdyne, provided lithium-ion (Li-ion) battery cells for use on the International Space Station (ISS).
“Over the past 3 years, GS Yuasa’s technology and manufacturing capability have been thoroughly evaluated by NASA,” Curtis Aldrich, GS Yuasa’s director of business development, assured the public.
Just today, U.S. investigators with the NTSB issued a request for Boeing to provide “a full operating history of lithium-ion batteries used in its grounded 787 Dreamliners.” At the same time, however, the Transport Ministry in Japan closed its investigation of GS Yuasa after having found no evidence that it was the source of the problems. This geek wants to know what you think of this dichotomy (contradiction? Opposing views?)
