Washington approves Boeing plan to fix batteries in plagued Dreamliners


WASHINGTON — A Boeing plan to redesign the 787 Dreamliner’s fire-plagued lithium-ion batteries won approval from the U.S. Federal Aviation Administration, although officials gave no estimate for when the planes would be allowed to fly passengers again.

The 787 fleet worldwide has been grounded by the FAA and civil aviation authorities in other countries since Jan. 16, following a battery fire on a Dreamliner parked in Boston and a smoking battery that led to the emergency landing of other 787 in Japan.
