Airport crews have contained a fuel leak from a Japan Airlines Boeing 787 in the second incident in two days involving the same model aircraft operated by the airline.
Massachusetts Port Authority spokesman Richard Walsh said the leak occurred at Boston's Logan Airport yesterday.
About 150 litres of fuel spilled.
The plane was due to depart for Japan with 178 passengers and 11 crew on board.
An airline spokeswoman said the crew had reported a ‘‘mechanical issue’’. The noon flight was rescheduled for mid-afternoon departure.
On Monday, a fire broke out in a battery pack in the belly of a different Japan Airlines Boeing 787, filling the cabin with smoke minutes after passengers disembarked. Federal transportation agencies are investigating.
