TOKYO (AP) -- U.S. transport safety regulators have asked Boeing Co. to provide a full operating history of the lithium-ion batteries used in its grounded 787 Dreamliners.

The National Transportation Safety Board said in a statement it made the request after recently becoming aware of battery incidents that occurred before a Jan. 7 battery fire in a 787 parked at Boston's Logan International Airport.

All Nippon Airways said Wednesday it had 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.

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.


TOKYO (AP) -- Japan's All Nippon Airways says it replaced lithium-ion batteries on its 787 Dreamliners 10 times before a battery overheating incident led to the worldwide grounding of the jets.

ANA spokeswoman Megumi Tezuka said Wednesday the airline was not required to report the battery swapping cases to Japan's Transport Ministry because they did not raise safety concerns and did not interfere with flights. Boeing was informed.

She said the batteries were replaced because they failed to charge properly or showed other problems.

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. Earlier, a battery in a Japan Airlines 787 caught fire while parked at Boston's Logan International Airport.
