The NTSB said that tests on lithium-ion batteries for 787 planes were inadequate, and has recommended new tests to determine whether batteries with new chemistries are safe for use on airliners. Boeing said in response that the tests the company conducted after the battery system was redesigned were consistent with the NTSB’s recommendations issued on Thursday. Late Thursday, the NTSB issued a statement that “as provided to us by Boeing,” the description of tests on the redesigned battery was “consistent with the N.T.S.B. recommendations.” The NTSB’s report indicates that the FAA relied too much on Boeing for technical expertise, and criticizes the process used by the FAA to certify the new jet in 2007.
