Japan Airlines says Boeing 787 fuel leak due to unclosed valve

TOKYO, Jan 9 (KUNA) -- Japan Airlines Co. (JAL) said Wednesday the cause of the fuel leak in its Boeing 787 Dreamliner at a US airport bound for Tokyo on the previous day is a malfunctioning valve.
"The valve on a pipe connecting the fuel tank in the aircraft's body with the left wing was open, and this caused fuel to spill out," JAL said. The fuel leak forced flight JL 007 with 181 passengers and 11 crew members to postpone takeoff.
The Boeing 787 Dreamliner was towed back to the gate after about 150 liters of jet fuel leaked when the plane was taxiing toward the runway for takeoff. All passengers temporarily disembarked and the aircraft eventually left for Tokyo after almost four hours. None of the passengers and crew on board was injured. JAL said it plans to inspect the aircraft further after it arrives in Tokyo's Narita Airport later in the day. It was the second incident in two days involving JAL's brand-new Dreamliner at the same airport.
On Monday at Logan Airport, an electrical fire erupted on another JAL-operated Dreamliner arriving from Tokyo shortly after passengers and crew disembarked. The fire broke out in a battery in the plane's auxiliary power unit, which is used when the jet's engines are turned off. The Dreamliner jet is Boeing's latest model. JAL has ordered a total of 45 Boeing 787 Dreamliners, including seven it is already operating. (end) mk.asa KUNA 091317 Jan 13NNNN
