Boeing 787 Probe Said to Focus on Pinched Beacon Wire

Investigators are examining whether a wire smashed under a beacon battery cover caused a short-circuit that triggered a July 12 fire on a Boeing Co. 787 Dreamliner in London, a person familiar with the probe said.

U.K. and U.S. investigators are focused on the crushed wiring in the plane’s emergency locator transmitter while continuing to look into a number of possible causes for the blaze, said the person, who isn’t authorized to speak publicly.
