No answers yet on Boeing 787 fire: US investigators
WASHINGTON (AFP) - United States (US) government investigators said on Thursday they could not yet explain what caused a potentially catastrophic battery fire aboard a Boeing 787 that forced the grounding of Dreamliners around the world.
National Transportation Safety Board chairman Deborah Hersman said investigators were working "around the clock" to understand what led to the Jan 7 fire aboard a parked Japan Airlines 787, as well as a smoking battery that forced the emergency landing of an All Nippon Airways 787 on Jan 16.
But she said that the systems designed to contain such an event on the all-new Dreamliner "did not work as intended." "This is an unprecedented event. We are very concerned. We do not expect to see fire events on board aircraft," Ms Hersman told reporters.
"The expectation in aviation is to never experience a fire on board an aircraft. In two weeks' time we saw two cases of battery failures on a 787 and the grounding of the entire fleet by the FAA. The significance of these events cannot be understated."
