U.K. authorities: Disable 787 transmitter

LONDON -- U.K. air accident investigators recommended Thursday that a Honeywell emergency transmitter be temporarily disabled on all Boeing 787 Dreamliners following a fire last week at Heathrow Airport.

The Air Accidents Investigation Branch also recommended a safety review of lithium-battery- powered emergency locator transmitter systems in other aircraft.

The investigators said it was not clear if the fire on the parked Ethiopian Airlines Dreamliner was caused by the transmitter's lithium-manganese dioxide batteries or a short near or around the transmitter, but recommended that the U.S. Federal Aviation Administration switch off the Honeywell transmitter in all Boeing 787s "until appropriate airworthiness actions" can be carried out. -- AP
