Lithium battery testing still not good enough, NTSB says

|By:, SA News Editor

The U.S. government failed to properly test the Boeing (BA +0.9%) 787 Dreamliner's lithium-ion batteries and relied too much on Boeing for technical expertise, a new report from the NTSB says in criticizing the process used by the FAA to certify the new jet in 2007.

The report directly conflicts with the FAA's own internal study released in March, which said the agency had "effective processes in place to identify and correct issues that emerged before and after certification."

Other aircraft, including the Boeing 777, recent versions of the company’s 737s and the Airbus A380 (EADSF, EADSY), have smaller lithium-ion batteries that were tested with the same flawed standards, the NTSB says.
