On Friday, the Federal Aviation Administration officially announced its approval of Boeing’s re-design for the 787 Dreamliner. Nearly four months after a series of alarming battery fires caused the FAA to the ground the aircraft, Boeing is eager to put its fuel-efficient fleet back in the air.

Modifications to the lithium-ion battery system include extra insulation around each of the battery’s eight cells to prevent short circuit fires from spreading, enhanced venting to move smoke from inside the battery to outside of the plane, and a strengthened box to further contain fires.

These changes, according to transportation secretary Ray LaHood, "will ensure the safety of the aircraft and its passengers."

While many airlines—including All Nippon Airways and Japan Airways—are also awaiting the 787’s release, any return to service will have to wait until the FAA accepts Boeing’s completed work.
