Japan Airlines’ Boeing 787, while maintenance at Narita International
Air;port, had a failure to leak about 100 liters of its fuel. The
incident took place around 1:40 pm on January 13 local time. According
to JAL, the aircraft is the one that showed fuel leakage at Boston Logan
International Airport on January 8 and while removing remaining fuel in
the left wing, JAL saw unexpected leak from jettison fuel nozzle of the
left wing.
The nozzle was most probably opened itself while maintenance work was performed; there was no display of warning that was supposed to be activated when the nozzle starts to work.
The fuel leak in Boston was caused by extra amount of fuel flowing to a fuel tank in the left wing as a unclosed valve that connect two fuel tanks of middle section of the fuselage and the left wing. The fuel leaked from another discharge section. Japan Airlines started its check up assuming a trouble of fuel supply system at both cases.■
