January 8, 2014 - The investigative work into
the Jan. 7, 2013, fire aboard a Japan Airlines
Boeing 787 (JA829J) at Logan International
Airport in Boston, is estimated to be completed
by the end of March, the National Transportation
Safety Board said today.
The analytical and report writing phase of the
investigation will follow the completion of the
investigative activities. The final report is
expected to be presented to the Board at a
public meeting in Washington in the fall.
Members of the investigative team have been
conducting work in the United States, Japan,
France, and Taiwan. As the investigation has
progressed, the NTSB has been working closely
with Boeing, the Federal Aviation
Administration, the Japan Transport Safety
Bureau, the French BEA, and technical advisors
from Japan and France.
Some of the investigative activities include:
- Completed disassembly and documentation of the
individual cells of the incident battery.
- Completed examinations of exemplar batteries
and battery cells for baseline reference and
comparison to the incident battery. These
examinations were conducted at NTSB and
independent laboratories and included computed
tomography scans, non-destructive soft short
testing, and destructive evaluation and analysis
of the batteries and cells.
