All Nippon Airways has confirmed it is going to resume Boeing Dreamliner flights in June after the Japan Civil Aviation Bureau issued a revised Technical Circular Directive for the plane.
ANA is the biggest operator of the aircraft on the earth, with a fleet of 17 Boeing 787s.
Ethiopia Airlines earlier became the primary carrier to come to the Dreamliner to service, with commercial flights beginning over the weekend.
Boeing was working with carriers to exchange potentially faulty batteries.
A series of incidents affecting the batteries saw the Dreamliner grounded in January, with Boeing engineers working “around the clock” to repair the issue over the last weeks.
Some 50 Dreamliners are presently in service world wide, which every having to be modified by a consultant Boeing team before it would return to the sky.
ANA is currently working with five Boeing support teams to retrofit new systems on its 787 aircraft.
This involves replacing existing batteries with new batteries, changing to new battery chargers and installing new battery containment boxes and venting system.
The improvements would require approximately one week per aircraft, with work on all seventeen aircraft scheduled to be completed by the top of May.
In addition to those modifications, ANA would be undertaking additional checks and tests to be sure the security of its aircraft and peace of mind of its passengers.
Osamu Shinobe, president, ANA said “Our priority is to make sure the security of our passengers.
“We are pleased that the Federal Aviation Authority and JCAB are satisfied with Boeing’s plans to handle the battery issues at the 787 aircraft and we’re working closely with Boeing and our own engineers to undertake these improvements.
“Only once we are fully satisfied with the security of our 787 fleet can we return the aircraft to service.”
