US approves resumption of Boeing 787 flights

Washington: Federal officials have accepted Boeing's revamped battery system for its beleaguered 787 Dreamliners and intend to lift a three-month-old order grounding the planes. The Federal Aviation Administration said in a statement on Saturday that it will next week send airlines instructions and publish a notice lifting the grounding order.

The lifting of the grounding order will be effective the day the notice is published. Lifting the grounding order gives Boeing the go-ahead to begin retrofitting planes with an enhanced lithium ion battery system.

The root cause of battery failures that led to a fire on one of the planes and smoke on another remains unknown. Flights could resume within a week.
