Japan Airlines said on Sunday that a Boeing 787 Dreamliner undergoing checks in Tokyo following a fuel leak at Boston Airport last week had leaked fuel during tests earlier in the day.An open valve on the aircraft caused fuel to leak from a nozzle on the left wing used to remove fuel, a company spokeswoman said. The jet is out of service after spilling about 40 gallons (roughly 150 litres) of fuel onto the airport taxiway in Boston due to a separate valve-related problem.In Boston, a different valve on the plane opened, causing fuel to flow from the centre tank to the left main tank. When that tank filled up, it overflowed into a surge tank and out through a vent. The spill happened as the plane was taxiing for takeoff on a flight to Tokyo on January 8. It made the flight about four hours later.The causes of both incidents are unknown, the JAL spokeswoman added. There is no timetable for the plane to return to service."We are aware of the event and are working with our customer," Boeing spokesman Marc Birtel said of the leak in Tokyo. Source: Reuters
