On January 7, 2013, approximately 1021 japanese commonplace time, smoke used to be chanced on by means of cleansing group of workers within the aft cabin of a Japan airways (JAL) Boeing 787-8, JA829J, which was once parked at a gate at normal Edward Lawrence Logan overseas Airport (BOS), Boston, Massachusetts. in regards to the comparable time, a upkeep supervisor within the cockpit saw that the auxiliary energy unit (APU)—the sole resource of plane strength on the time—had immediately close down. presently in a while, a mechanic opened the aft digital apparatus (E/E) bay and located heavy smoke and hearth coming from front of the APU battery case.2 No passengers or crewmembers have been aboard the aircraft on the time, and not one of the upkeep or cleansing body of workers aboard the aircraft was once injured. airplane rescue and firefighting team of workers replied, and one firefighter acquired minor accidents. The plane had arrived from Narita overseas Airport, Narita, Japan, as an often scheduled passenger flight operated as JAL flight 008. The APU battery presents energy to begin an APU in the course of flooring and flight operations. Flight info recorder (FDR) facts confirmed that the APU was once began approximately 1004 whereas the aircraft used to be being taxied to the gate after arrival at BOS. The FDR info additionally confirmed that, approximately 36 seconds sooner than the APU close down at 1021:37, the voltage of the APU battery all started fluctuating, shedding from an entire cost of 32 volts to twenty-eight volts approximately 7 seconds sooner than the shutdown. The APU battery involves 8 lithium-ion cells which are hooked up in sequence and assembled in rows of 4 cells. every one battery mobilephone has a nominal voltage of 3.7 volts. The cells have a lithium cobalt oxide compound chemistry and include a flammable electrolyte liquid.
