Japan airlines replaced Boeing 787 batteries many times
TOKYO (AP) - All Nippon Airways and Japan Airlines said they replaced lithium-ion batteries in their Boeing 787 Dreamliners on multiple occasions before a battery overheating incident led to the worldwide grounding of the jets.
ANA said on Wednesday it replaced batteries on its 787 aircraft some 10 times because they failed to charge properly or showed other problems, and informed Boeing about the swaps.
Japan Airlines said it had also replaced lithium-ion batteries on its 787 jets but could not immediately give details.
All 50 of the Boeing 787s in use around the world were grounded after an ANA flight on Jan 16 made an emergency landing in Japan when its main battery overheated.
