Boeing battery cleared in Dreamliner problems
A Boeing 787 Dreamliner operated by All Nippon Airways (ANA) sits on the tarmac after an emergency landing at Takamatsu Airpirt in Takamatsu, west of Japan, on January 16, 2013. Japan’s two biggest airlines on January 16 grounded all their Dreamliners in the most serious blow yet to Boeing’s troubled next-generation model after an ANA flight was forced into an emergency landing.
The battery is not to blame for ongoing problems with Boeing's 787 Dreamliner, US and Japanese officials said Monday.
The investigation now shifts from battery-maker GS Yuaka to the manufacturer of a monitoring system, The Associated Press reported.

All 50 of Boeing's 787 Dreamliners are grounded worldwide following numerous incidents involving the aircraft earlier this month.
Battery fires, a cracked windshield, fuel leaks and computer problems were reported.
GS Yuasa stock jumped on the news it is no longer being investigated, gaining nearly 5 percent in Tokyo trading, CBS News reported.

The focus has now shifted to the electrical system that monitors battery voltage, charging and temperature.
"We are looking into affiliated parts makers," Japan transport ministry official Shigeru Takano told BBC News. "We are looking into possibilities."
While the ongoing investigation may prolong the Dreamliner's grounding, the shift away from a faulty battery raises the prospects of Boeing not having to do a major redesign, Keith Hayward, head of research at the Royal Aeronautical Society, told BBC News.
According to Agence France-Presse, US regulators have said they will not allow the 787 to fly again until they are sure its problems have been fully resolved.
