We're a world leader in delivering complex, contoured structures with the latest and most innovative materials.

Spirit AeroSystems produces nacelle products such as thrust reversers, fan cowls and inlets for products ranging in size from business jets to large commercial aircraft.

One of Spirit’s most readily recognizable products is the under-wing component package that includes a nacelle/thrust-reverser and pylon configurations for every 737, 747, 757, 767, and 777 commercial airline product designed by Boeing. Spirit AeroSystems also holds the engineering and certification authority on all the commercial airplane under-wing components.


This experience with the design, fabrication and assembly of complex, multi-contoured, light-weight, acoustically treated nacelle and thrust-reverser components makes Spirit AeroSystems a prime source of product development for future commercial, defense, and general aviation engine interface structural packages.

Spirit’s pylon capabilities program provides include fairings, primary and secondary structures and systems on most regional and large commercial jets. Our pylon manufacturing and design techniques incorporate exacting interface tolerances, while supplying fully integrated electrical/environmental system components, for a turn-key assembly with a high strength-to-weight performance quotient.

The nacelle and pylon under-wing products supplied by Spirit AeroSystems feature state-of-the-art designs that are environmentally and regulatory compliant, safe, lightweight, durable and capable of delivering superior acoustic performance and enhanced engine performance via fuel-burn efficiency.We design, fabricate, assemble and deliver products using our skilled knowledge and personnel including engineering, materials testing, NC programming, planning and supply chain management.

We have extensive experience in providing on-time customer delivery from our world-class facilities where we manufacture composite and metal nacelle hardware, as well as metal pylon hardware. We design and manufacture with innovative material applications using the latest technology including complex machining, composites, and noise abatement.
