Generate lift and carry fuel and engine loads.
Wing boxes, ribs, spars, skins and wingtip devices carry different loads and have different supplier boundaries. A wing-structure reference does not establish supply of a complete 737 wing.
Program applicability is stated for each listing. 737NG, 737 MAX, and other aircraft examples are distinct configurations; listed products are not automatically interchangeable or approved for installation.
Supplies primary and secondary wing structures and leading- and trailing-edge assemblies. [1]
General wing capability; 737 applicability unverified [1]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
Provides wing design, industrialization and manufacturing for aircraft programs. [2]

Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
The product profile identifies composite main-wing production for the 787. [3]
Other aircraft — 787; no 737 main-wing applicability established [3]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
Manufactures the outer-wing trailing-edge falsework extension for the A330neo. [4]
Other aircraft — A330neo; no 737 applicability established [4]
Contact the manufacturer or aircraft OEM for the applicable approved program and configuration. This is an inquiry route, not an assertion of stock, price or installation eligibility.
A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.
Wingtip changes alter loads and require an aircraft-level integration assessment.
Compare bending, torsion, engine attachment and landing cases for the exact variant.
The location of mass affects flutter and inertia as well as total aircraft mass.
Obtain aeroelastic substantiation for the complete configuration.
Compare sealing, access and compatibility where the wing also forms a tank.
Review protection paths across skins, joints and composite interfaces.
Separate complete boxes, skins, ribs and fairings when comparing suppliers.
Evaluate access, repair limits and service documentation.
Specifications belong to the named product and configuration.
Public source establishes the product/work package, but does not publish comparable component mass, load limits or envelope. Request controlled drawings and configuration data through the aircraft program.
