Ethiopian 787 in LHR - ELT Battery on fire?
Neelam Mathews July 16, 2013 Investigators of Britain's Air Accident Investigations Branch (AAIB), and FAA are looking into whether a fire on the Ethiopian 787 at LHR l ast week was caused by the battery of an emergency locator transmitter built by Honeywell International. Powered by a non-rechargeable lithium-manganese battery, the ELT is located in the aft fuselage section. Airlines were told in 2009 by the FAA to replace a Honeywell transmitter that had failed in tests. Honeywell is believed to be checking whether the transmitter on the Ethiopian Airlines was the same model as the one named by FAA.
