Investigators Home In on Source of 787 Fire

The U.S. National Transportation Safety Board confirmed today that the fire that broke out Monday in a Japan Airlines Boeing 787 at Boston Logan Airport emanated from the airplane’s aft electrical equipment bay, near the APU battery box. According to the NTSB, an investigator on scene found that the auxiliary power unit battery showed severe fire damage. Thermal damage to the surrounding structure and components didn’t spread beyond the area immediately near the APU battery rack (within about 20 inches), it added.
