The U.S. Air Force today lifted a two-week-old flight ban that had grounded Lockheed Martin Corp.’s F-35 Joint Strike Fighter, following a power problem on a plane at Edwards Air Force Base in California.
An investigation found there was a defective valve in the plane’s Integrated Power Package, a turbo machine that provides power to start the engine, according to an Air Force statement.
