Boeing 777X Wing & Tail Parts in Production in St. Louis Including Innovative Folding Wingtip

    Production of 777X wing edge and tail parts is underway in St. Louis. Boeing is building major composite parts of the forthcoming 777X jet at Boeing’s St. Louis Composite Center of Excellence. The composites include pieces of the 777X wing’s fixed leading edge, the panels for that leading edge, the movable trailing edge and the jet’s innovative folding wingtip. St. Louis will also build the movable parts of the 777X tail: the rudder and elevators. Boeing partnered with the U.S. Department of Energy’s Oak Ridge National Laboratory (ORNL) to create a tool used to build the folding wingtip. The wing trim and drill tool is now the world’s “largest solid 3-D printed item,” certified by Guinness World Records.
