Start Preamble

On January 7, 2013, about 1021 eastern standard time, smoke was discovered by cleaning personnel in the aft cabin of a Japan Airlines (JAL) Boeing 787-8, JA829J, which was parked at a gate at General Edward Lawrence Logan International Airport (BOS), Boston, Massachusetts. About the same time, a maintenance manager in the cockpit observed that the auxiliary power unit (APU)—the sole source of airplane power at the time—had automatically shut down. Shortly afterward, a mechanic opened the aft electronic equipment bay and found heavy smoke and fire coming from the front of the APU battery case. No passengers or crewmembers were aboard the airplane at the time, and none of the maintenance or cleaning personnel aboard the airplane was injured. Aircraft rescue and firefighting personnel responded, and one firefighter received minor injuries. The airplane had arrived from Narita International Airport, Narita, Japan, as a regularly scheduled passenger flight operated as JAL flight 008 and conducted under the provisions of 14 Code of Federal Regulations Part 129.

The investigative hearing is being held to discuss the Boeing 787 battery and battery charger system. Areas that will be discussed include the selection and certification requirements, the battery system design, development, verification and validation processes and the FAA finding of compliance. The goals of this hearing will be to gather additional information on the selection of the lithium ion (Li-ion) battery technology and how this new technology was evaluated, the role of the prime contractor and subcontractors, development of the battery system safety assessment, certification process structure and findings of compliance for the Boeing 787 Li-ion battery system.

Parties to the hearing include the Federal Aviation Administration, The Boeing Company, Thales Avionics and GS Yuasa.
