NTSB to provide investigative update and photo opportunity of lab work related to Boeing 787 battery fire in Boston

January 23

WASHINGTON - Tomorrow, National Transportation Safety Board Chairman Deborah A.P. Hersman will provide an update on the NTSB's investigation of the Jan. 7 fire aboard a Japan Airlines (JAL) Boeing 787 at Logan International Airport in Boston.

Chairman Hersman will brief credentialed members of the news media on the progress of the investigation, after which she and senior staff will take questions. Those unable to attend in person can call in to a teleconference line.

Reporters will then be invited to view the materials laboratory where the battery is being examined. Photography will be allowed but no "stand-ups" or taped reporting from the lab will be permitted.

For planning purposes, RSVP is required for those planning to either attend in person or call in.

Location: NTSB Boardroom and Conference Center, 429 L'Enfant Plaza East, SW, Washington, DC

Date: Thursday, January 24, 2013

Time: 2:30 p.m.

Participants: Chairman Deborah A.P. Hersman; John DeLisi, Director of NTSB Office of Aviation Safety; and Dr. Joseph Kolly, Director, NTSB Office of Research and Engineering.

The following factual information has been developed about the battery: It consists of eight cells of 3.7 volts each. All eight cells had varying degrees of thermal damage. Six of eight cells have been CT scanned and have been disassembled to expose their electrodes. All electrode windings in the battery are in the process of being photo-documented and are undergoing microscopic examination. In the coming days, the remaining two cells will undergo the same examination. Additional information will be provided tomorrow.

NTSB Materials Engineer Matt Fox examines the casing from the battery involved in the JAL Boeing 787 fire incident in Boston.

In addition to the activities detailed above at the NTSB lab in Washington, members of the investigative team have been conducting work in Arizona, Seattle and Japan. Details of their activities will be provided at tomorrow's briefing.
