Dreamliner: Japan and US probe battery maker, battery charger issafe or not All 50 Dreamliners in operation arecurrently groundedThis news comes from BBC and talk about battery problems. And it has a greatsignificance.US and Japanese authorities have begun a joint investigation into GS Yuasa, theJapanese battery maker for Boeings troubled 787 Dreamliner aircraft.
It comes after an All Nippon Airways (ANA) 787 had to make an emergency landingdue to a battery malfunction.However, another US regulator said on Sunday the battery did not overcharge in aseparate incident involving a Japan Airlines (JAL)-operated 787.Regulators have grounded all Dreamliners currently in operation.
ANA has announced 335 Dreamliner flight cancellations including up until nextSunday. This is set to affect 48,000 passengers, including almost 4,000 internationalpassengers.Widening probeYasuo Ishii, a Japanese transport ministry safety official, said: "Engineers from the[US Federal Aviation Administration], Boeing and our aviation bureau started a probethis morning that is mainly focusing on GS Yuasas production line."They are checking on whether there have been any issues in the production process.We still dont know what caused the battery problem, and so we are looking into allpossibilities."Japanese battery maker GS Yuasa has seen its shares fall 11% since 7 January whenan electrical fire broke out on a JAL 787 at Logan International Airport in Boston,although they rebounded 1% on Monday as it became apparent the fault may nothave been a pure battery problem.
Investigating that incident, the US National Transportation Safety Board (NTSB) saidthe battery did not overcharge.
"Examination of the flight recorder data from the JAL B-787 airplane indicates thatthe [auxiliary power unit] battery did not exceed its designed voltage of 32 volts,"the NTSB said in a statement on Sunday.It said it would now widen its probe to look at the battery charger and the auxiliarypower unit.GS Yuasa also produces batteries for motorbikes, industrial equipment and powersupply devices.Smoke damageLast week, the Federal Aviation Administration (FAA) said both batteries had leakedelectrolyte fluid, and there had been smoke damage to parts of the aircraft.The NTSB said a group of experts would meet in Arizona this week, where thebattery charger is manufactured by Securaplane Technologies, to test and examinethe part.The battery charger maker, a unit of Britains Meggitt, said it would fully support theUS investigation. United Technologies, which builds the aircrafts auxiliary power unit,said it would also cooperate.On Friday, Boeing said it would put deliveries of the 787 on hold until the FAAapproved its plan to ensure the safety of the batteries.It said it would, however, continue building the light -weight fuel-efficient plane.
Japan is the biggest buyer of the aircraft, with ANA and JAL operating 24 of the 50Dreamliners currently in operation.Boeing has orders for more than 800 Dreamliners.Pick up some high quality battery charger to power mobile devices is important, ifnot, maybe it would cause accident.
