Boeing working with JAL on 787 fire at Boston airport
A battery explosion and subsequent fire damaged a parked and empty Japan Air Lines (JAL) Boeing 787 shortly after landing at Boston Logan International airport following a nearly 12h flight from Tokyo.
One battery in the aircraft's aft electrical equipment bay exploded on the aircraft and caused a secondary fire while it was parked at a gate on Logan's terminal E, says the airport operator Massport. Massport fire and rescue, and the Boston fire department extinguished the fire.
The 787 is one of the first aircraft to use lithium ion batteries, which is used to drive the main and auxiliary power units, fire control electronics, emergency lighting and the recorder's independent power supply, The Airbus A380 also uses lithium ion batteries, but only to supply power to the emergency lighting system.
But lithium ion batteries also are a source of safety concerns for aviation, in general. In 2007, the US Federal Aviation Administration outlined some of those concerns in a special airworthiness rule for the 787, noting that over-charging such batteries can cause them to explode and ignite secondary fires. But Boeing convinced the agency that lithium ion batteries can be operated safely in modern aircraft.
Boeing says it is aware of the incident and is working with JAL on the issue, the latest in a series of high-profile electrical system glitches plaguing 787 operators since early December.
