Boeing began installing reinforced lithium ion batteries on five grounded 787 jets owned by launch customer All Nippon Airways yesterday, starting a process that should make the first commercial Dreamliners ready to fly again in about a week.

Teams of Boeing engineers are working on the ANA jets at four airports inJapan, including Tokyo’s Haneda and Narita hubs, Ryosei Nomura, a spokesman for the carrier said.

The Dreamliners have been parked since regulators in the United States and elsewhere ordered all 50 planes out of the skies in mid-January after batteries on two of them overheated.

ANA is the world’s biggest operator of the carbon-composite aircraft with 17 of the planes. After ANA, the biggest 787 operator is local rival Japan Airlines Co with seven jets, followed by United Continental Holdings’ United Airlines and Air India AIN.UL with six each.

ANA plans about 100 to 200 round trip test flights in May of its repaired aircraft before carrying passengers again from June, sources knowledgeable about ANA’s operations told Reuters last week. The flights will check the safety of the aircraft, and allow ANA’s 180 Dreamliner pilots to get accustomed to flying it again and renew their licenses after more than a three-month break. ANA has not said how much the 787’s grounding has cost it to date, though it has said it lost about $900,000 in revenue per plane in the last two weeks of January. The grounding has cost Boeing an estimated $600 million.
