The battery underwent an X-ray CT scan at an independent test facility this weekend “to document the internal condition of the battery prior to disassembling it,” the agency said in an update on its inquiry into the fire.
Investigators also removed burned wire bundles, the battery charger and several electronic-control memory modules.
The two combined flight-data and cockpit voice recorders from the jet were taken to NTSB headquarters as well. The flight data is being analyzed by the investigative team.
