Japanese battery-making company says probe into Dreamliner problem may take months

Tokyo, Jan. 18 (ANI): A Japan-based company that makes batteries used on Boeing Co.'s new 787 planes have said it will take months to complete an investigation into what caused an emergency landing of an All Nippon Airways Co. Dreamliner

GS Yuasa Corp spokesman Hiroharu Nakano said that it needs to find out whether the emergency landing on Wednesday in Kagawa Prefecture was caused by an issue with its battery or the entire electrical system.

Nakano said that the plane's electrical system needs to be dismantled for the investigation.

According to the Japan Times, shares of Kyoto-based GS Yuasa fell as much as 7.5 percent, the most in almost three months, after a suspected battery fire on the ANA jet led to the grounding.

Nakano said that they will first look at the battery, but before that they have to check if the battery was the only problem or there's an entire electrical system issue.

The 787 is the first plane to make extensive use of lithium ion batteries, which have raised concerns in the past for their potential to catch fire, the report said.

The Federal Aviation Administration, FAA, has given the batteries extra scrutiny and issued a special rule for their use in the 787.

The plane has two batteries - the main one near the front and a second one in the rear.

According to the report, Boeing and the airlines will need to move quickly to determine whether the problem is a flaw in the batteries themselves, in the plane's wiring or in some other area that's fundamental to the plane's electrical system.

Boeing has booked orders for more than 800 of the planes from airlines around the world attracted by its increased fuel efficiency.

U.S. regulators have temporarily grounded the 787s after All Nippon and Japan Airlines Co. grounded the entire fleet of Dreamliners.

The regulators announced Jan. 11 they were conducting a review of the Dreamliner's design, manufacturing and assembly in the wake of a Jan. 7 fire aboard a Japan Airlines 787 in Boston, the report added. (ANI)
