Report on 787 batteries assigns some blame for flaws
Flaws in manufacturing, insufficient testing and a poor understanding of an innovative battery all contributed to the grounding of Boeing’s 787 fleet last year after a fire in one jet at Boston’s airport, according to a report released Monday by federal regulator (www.nytimes.com) さらに...Sort type: [Top] [Newest]

Poor understanding of an innovative battery? Five years before it flew, those batteries were known to burn due to cell damage. Where the design engineers living under rocks?

It sounds like they were heading into unknown territory and made assumptions about end-point conditions that, in retrospect, did not match the actual conditions. Sort of like the design conditions for Galloping Gertie, the ill-fated Tacoma Narrows Bridge.
It depends on which article you read but the first one posted before this one does not say it should not have been certified just this article. It says that it was not tested enough or proplerly only in the other one. Anyway this is a repost.
At least this one contained a link to the report itself.
