FAA took faulty Boeing test results, agency says

Battery risks assessed poorly, NTSB indicates

The nation’s top transportation safety official said Thursday that the Federal Aviation Administration accepted test results from Boeing in 2007 that failed to properly assess the risks of smoke or fire leaking from the batteries on Boeing’s new 787 jets.

Deborah Hersman, National Transportation Safety Board chairwoman, told reporters Boeing predicted that the batteries on its new 787 planes were likely to emit smoke less than once in every 10 million flight hours.
