Officials in Boston contain Dreamliner jet fuel leak

NEW YORK Officials at Boston's Logan International Airport say crews have contained a fuel leak from an outbound Japan Airlines flight to Tokyo, marking the second time in two days that JAL planes at Logan reported problems.

Massachusetts Port Authority spokesman Richard Walsh said the Boeing (BA) 787 was towed back to the gate Tuesday after about 40 gallons of fuel spilled. He said the plane had 178 passengers and 11 crew members on board. Walsh said the plane was evaluated and departed that afternoon.

A JAL spokeswoman said the crew had reported a "mechanical issue."

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 the fire.
