Boeing working on 787 battery design changes to cut fire risk: Report
Washington: Aerospace giant Boeing is working on a series of battery design changes, a report has said.
According to the Wall Street Journal, the new designs are aimed at minimizing fire risks on its grounded 787 passenger jet.
Last week, Boeing sought the permission of the US Federal Aviation Administration (FAA) to conduct test flights of its 787 Dreamliner passenger plane.
All 50 of Boeing's 787s were grounded last month because of an ongoing investigation into battery problems.
A battery on a Japan Airlines 787 caught fire, and a malfunction forced an All Nippon Airways flight to make an emergency landing.
Peter Conte, a spokesman for Boeing, said that the firm's application was "under evaluation" by the FAA.
