Boeing on Monday began installing reinforced lithium-ion batteries on five grounded 787 jets operated by launch customer All Nippon Airways, starting a process that should make the aircraft ready to fly again in about a week.
Teams of Boeing engineers are working at four airports in Japan, including Tokyo's Haneda and Narita hubs, where the 787s have been parked since regulators worldwide ordered all 50 planes out of the skies in mid-January after batteries on two of them overheated.
With 17 of the aircraft, ANA is the biggest operator of the carbon-composite aircraft. After ANA, local rival Japan Airlines has seven 787s, followed by United Airlines and Air India with six each.
