Japan Airlines explains 787 fuel leak in Boston

BOSTON (AP) - Japan Airlines is giving more details about a fuel leak on one of its Boeing 787s that delayed a flight from Boston to Tokyo.

A spokesman said on Wednesday one of four valves connecting the centre and left main fuel tanks was open. That led to fuel flowing between those tanks to a surge tank near the wing tip and then out a vent, spilling about 150 litres.

She says that valve was deactivated and the flight was cleared to depart later on Tuesday. A more detailed inspection was scheduled in Tokyo.

The leak on Tuesday was the second problem in two days for Japan Airlines at Boston Logan. A fire broke out in a battery pack in the belly of a different Boeing 787 on Monday, after passengers had exited.
