WASHINGTON (AP) -- Federal officials have accepted Boeing's revamped battery system for its beleaguered 787 Dreamliners and intend to lift a 3-month-old order grounding the planes.

The Federal Aviation Administration said in a statement Friday that next week it will 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.
