A fire broke out on a Boeing 787 Dreamliner jet in Boston's Logan Airport after a non-stop flight from Tokyo, prompting safety concerns about the new plane.
No one was on board at the time.
The incident occurred Monday when an electrical fire broke out on board the Japan Airlines jet 30 minutes after 173 passengers and 11 crew members exited.
The Massachusetts Port Authority's fire chief, Bob Donahue, said the fire began in a battery pack for the auxiliary power unit, which runs its electrical systems.
No major injuries were reported, although one firefighter experienced skin irritation after contact with a chemical used to douse the fire, Donahue said.
The flight landed incident-free around 10:15 a.m., but a mechanic working in the cockpit was confronted minutes later by smoke billowing from electrical systems.
"We observed a heavy smoke condition throughout the entire cabin," Donahue said.
Fire crews using infrared equipment found flames in a small compartment in the plane's belly and had the fire put out in about 20 minutes, he said.
There was a flare-up later when a battery exploded, he added.
Japan Airlines said in a statement:
"Safety is the foundation of JAL's operations and while no passengers were injured in this incident, we deeply apologize for causing our customers concern and inconvenience."
"We are now working closely with NTSB and Boeing in determining the cause."
The National Transportation Safety Board said it's sending an investigator to Boston. The FAA also said it was investigating, according to The AP.
"We're aware of the situation and are working with our customer," Boeing said.
Boeing has sold more than 800 of the planes around the world with only six flying domestically. The plane, mostly made of carbon fiber, was first released in 2011.
The FAA last month ordered inspections of potential fuel-line leaks on all 787s.
On the same day the inspection was ordered, a United Airlines 787 flight from Houston to Newark, N.J., was diverted to New Orleans due to generator failure.
A similar fire broke out during the 787's testing phase in 2010.
