Spirit Aero Systems plays a pivotal role in the Boeing 737 program, holding the design and build responsibility for the aircraft’s complete fuselage, including both the forward and aft sections. This critical work involves creating the main body structure of the plane, ensuring its aerodynamic performance, structural integrity, and safety.

In addition to the fuselage, Spirit Aero Systems also takes on significant responsibilities in the wing and propulsion systems. Their work packages include various components and assemblies that are integral to the aircraft’s overall structure and functionality. These contributions range from intricate aerodynamic surfaces to key structural supports for the engines.

This collaboration between Spirit Aero Systems and Boeing underscores Spirit’s expertise in aerostructures and their essential role in the production and assembly of one of the world’s most popular commercial aircraft. Their deep integration into the 737 program highlights the importance of advanced manufacturing and engineering in modern aviation.
