This occurred on 12 July 2013, at London Heathrow Airport
This Special Bulletin contains information on the progress of the investigation into a ground fire on an unoccupied Boeing 787-8, registration ET-AOP, at London Heathrow Airport on 12 July 2013.
It follows the publication of Special Bulletin S5/2013 on 18 July 2013. The AAIB are assisted in the investigation by Accredited Representatives from the National Transportation Safety Board (NTSB) (representing the State of Design and Manufacture), the Civil Aviation Authority of Ethiopia (representing the State of Registry and the Operator) and the Transportation Safety Board (TSB) of Canada (representing the State of component manufacture), with technical advisors from the Federal Aviation Administration (FAA), the operator and the aircraft and component manufacturers.
In Special Bulletin S5/2013, the AAIB reported the existence of extensive heat damage in the upper portion of the aircraft’s rear fuselage, particularly in an area coincident with the location of the Emergency Locator Transmitter (ELT). The absence of any other aircraft systems in this area containing stored energy capable of initiating a fire, together with evidence from forensic examination of the ELT, led the investigation to conclude that the fire originated within the ELT battery.
Five Safety Recommendations are made.
