The Federal Aviation Administration (FAA) has signed off on the company’s plan to modify the lithium-ion batteries used in the high-tech jet to prevent overheating. Under the new plans, Boeing will apply new venting, containment and insulation features to the batteries, the Associated Press notes.
A U.S. Representative from Washington state, where Boeing is based, told the AP that the FAA could clear the Dreamliners for flight by the end of April, if the redesign fares well in series of laboratory tests and trial flights. Two test flights for the new design have already been approved.
Boeing would then have to install the new battery designs in the 50 Dreamliner jets that have already been delivered to airlines around the world.
All Dreamliners were grounded in January after a series of incidents led to emergency landings and a fire in the belly of a 787 on the ground at Boston’s Logan airport.
Shares of Boeing rose fractionally in pre-market trading on Wednesday.
