NTSB RELEASES INTERIM FACTUAL REPORT ON JAL 787 BATTERY FIRE
INVESTIGATION AND ANNOUNCES FORUM AND INVESTIGATIVE HEARING 
March 7, 2013 
WASHINGTON - Today, the National Transportation Safety Board
released an interim factual report and 499 pages of related
documents in its ongoing investigation of the Japan Airlines 787
battery fire in Boston. Additionally, NTSB Chairman Deborah A.P.
Hersman announced today that the NTSB will be holding both a
forum and a hearing in April to provide additional information
to advance the investigation. 
“With the grounding of the 787 fleet, concurrent international
incident investigations, redesign and re-certification
activities taking place simultaneously, it is essential to
provide the aviation community, policy makers and the public
with the factual information we are developing,” said Hersman.
“Releasing an interim report provides a window into the
significant investigative work that has been accomplished so
far.” 
The forum, which will be held in mid-April, will explore
lithium-ion battery technology and transportation safety. The
investigative hearing, to be held later in April, will focus on
the design and certification of the 787 battery system. 
“The information developed through the upcoming forum and the
hearing will help the NTSB and the entire transportation
community better understand the risks and benefits associated
with lithium batteries, and illuminate how manufacturers and
regulators evaluate the safety of new technology,” Hersman said. 
Both proceedings, which will be held at the NTSB Board Room and
Conference Center in Washington, will be webcast live and will
be open to the public. Additional details about each event,
including dates, times, agendas and participants, will be
released in the coming weeks. 
The 48-page interim factual report summarizes the NTSB’s initial
findings on the JAL battery fire investigation. The report
includes details on how the maintenance personal discovered the
fire and how the firefighters responded and extinguished it,
findings from the examination of the battery and test results of
related components, initial reports on the flight recorder data,
a description of the 787 electrical power system certification
plan, and a list of ongoing and planned investigative
activities. 
The other documents released today provide additional details on
various aspects of the investigation. All of these documents are
available in the NTSB’s JAL 787 public docket, which was opened
today: http://go.usa.gov/2Dck. 
As the investigation progresses, additional factual materials
will be added to the docket. The analysis of the factual
information already provided as well as that yet to be
developed, will be completed at a later date. 
Additional information related to the JAL 787 battery fire
investigation is available on a web page dedicated to that
incident: http://go.usa.gov/4K4J.
