A Japan Airlines plane that
was scheduled to take off from Boston's Logan International Airport
Tuesday was stopped after fuel was reported coming from the plane.
The 787 was stopped on Runway 22, and towed back to the gate after about 40 gallons of fuel was discovered on the ground, Massport said.
Flight 7, with 178 passengers and 11 crew members, was scheduled to leave Boston at noon, bound for Tokyo.
The crew reported a "mechanical issue" before returning to the gate, a JAL spokeswoman said. The flight was en route to Japan shortly after 5 p.m.
"Vents are there in case of over fueling or if there's a transfer of fuel," said Ed Freni, Massport director of aviation. "If the engine were leaking, that's a different situation than fuel coming out of a designed area to vent."
On Monday, firefighters at Logan doused smoke aboard a Japan Airlines Boeing 787 after a mechanic working in the cockpit of the jet was confronted by smoke billowing from electrical systems in the belly of the plane. There were no passengers on the plane at the time.
It was not the first incident for the Dreamliner since its 2011 release. A United Airlines 787 flying from Houston to Newark, N.J., last month was diverted to New Orleans because of an electrical problem with a power distribution panel. No one was injured.
The Dreamliner is made of carbon fiber and uses electrical motors instead of hydraulic motors to save weight and energy.
"As a result, the electrical system has to be much more powerful and it runs at a higher voltage," MIT professor John Hansman said. "There has been a fire in this area in one of the 787 flight tests airplane several years ago during flight tests."
