First 737 MAX Wing Assembly

Assembly of the first 737 MAX in our Renton, Wash., facility kicks off with wing assembly for the first 737 MAX flight test airplane.

Wing skin panels and stringers were loaded into the new panel assembly line and initial parts of the first 737 MAX spars – internal support structures in wings – were loaded into automated spar assembly machines. When finished, the panels and spars will be transformed into completed wings.


Line Quality inspectors inspect 737 MAX wing skin panels and stringers in the new panel assembly line that uses automation to drill holes and install fasteners in the upper and lower wing panels. The skins and stringers were machined by Boeing Fabrication Skin and Spar in Auburn and Fredrickson, Wash.
