On January 7, 2013, approximately 1021 japanese general time, smoke was once came upon by means of cleansing body 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 foreign 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 instantly close down. presently later on, a mechanic opened the aft digital apparatus (E/E) bay and located heavy smoke and fireplace 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 team of workers aboard the aircraft was once injured. airplane rescue and firefighting group of workers spoke back, and one firefighter acquired minor accidents. The plane had arrived from Narita overseas Airport, Narita, Japan, as a frequently scheduled passenger flight operated as JAL flight 008. The APU battery presents strength to begin an APU in the course of flooring and flight operations. Flight information recorder (FDR) info confirmed that the APU was once begun approximately 1004 whereas the plane used to be being taxied to the gate after arrival at BOS. The FDR info additionally confirmed that, approximately 36 seconds prior to the APU close down at 1021:37, the voltage of the APU battery started fluctuating, losing from an entire cost of 32 volts to twenty-eight volts approximately 7 seconds earlier than the shutdown. The APU battery includes 8 lithium-ion cells which are hooked up in sequence and assembled in rows of 4 cells. each one battery phone has a nominal voltage of 3.7 volts. The cells have a lithium cobalt oxide compound chemistry and include a flammable electrolyte liquid.
