FAA investigating how titanium parts with falsified records wound up in Boeing and Airbus planes

Federal officials are investigating how parts made with titanium sold with falsified documentation wound up in Boeing and Airbus passenger jets. The Federal Aviation Administration confirmed its investigation on Friday. Boeing and Airbus say planes that contain the parts are safe to fly, but Boeing is removing affected parts from planes that haven’t been delivered yet to airlines. Spirit AeroSystems, which makes big aircraft parts for both Boeing and Airbus, reported the falsified documents to Boeing, which in turn notified the FAA. Boeing and Airbus declined to say how many planes were built with parts made from the undocumented titanium.
