Boeing did n’t develop the battery on its own . Much of the body of work was subcontract out to the firms Thales and Securaplane . Theinterim reportfrom the Airworthiness investigation squad found that while the company each do thousands of hours of testing on the barrage fire system ’s element , none of the caller could produce proof that they ’d performed “ complete life - cps trial run ” on the integral assembled barrage organization . In other Book , nobody put the whole the whole matter together and strain to make it fail .
That alone would be loose-fitting , but it ’s even worse because we ’re peach about an entirely raw type of battery technology that the FAA was disturbed about . The Dreamliner is the first airplane to utilize a lithium - ion rechargeable electric battery . The FAA did a study and resolve that this probably was n’t a serious musical theme to begin with . According tothe System Safety and Certification team ’s paper :
The FAA noted that other users of this technology , ranging from wireless telephone fabrication to the electric fomite industriousness , have note safety problems with lithium - ion battery , which included overcharging , over - discharging , and inflammability of cellular phone part .
Li - ion batteries are the same case used in smartphones , which as we jazz , ofttimes fail and sometimes even blow up . Boeing establish this risky intent change into the Dreamliner without equal examination . As the writer of the APEX storypoints out on her web log , the safety and certificate composition has “ a blizzard of documents , calculation , schematics and diagram from Boeing ” that would make you think that the tests were thoroughgoing . The NTSB investigating is n’t done , but it ’s looking more and more like Boeing did a jerry-built job and the FAA rubber stamp it .

We reached out to Boeing for comment and we ’ll update when they answer . [ NTSBviaAPEX ]
Update : We contacted Boeing for comment on the NTSB report and a spokesperson distinguish us :
Release of the National Transportation Safety Board ( NTSB ) interim report is a positive measure in the progress toward finish the investigation of the Jan. 7 event in Boston . The Boeing team has figure out tirelessly in support of the NTSB to help train an understanding of the event and will go along to do so .
The 787 was certified following a rigorous Boeing mental testing program and an encompassing authentication programme conducted by the FAA . We provided testing and analytic thinking in support of the requirements of the FAA special conditions associated with the use of Li ion battery . We are work collaboratively to address questions about our examination and compliance with credentials criterion , and we will not hesitate to make changes that result to improved testing processes and products .
