Sonaca do Brasil

Sonaca do Brasil Ltda is a tier-one aerostructures manufacturer based in São José dos Campos. The company serves as a strategic production hub for its European parent group, specialising in the development and manufacture of complex metallic and composite assemblies. Within the aerospace value chain, the organisation functions as a direct supplier of integrated structural modules, specifically focused on wing and fuselage components for commercial and executive aviation. The firm maintains a deep industrial relationship with Embraer, providing critical sub-assemblies for several major aircraft programmes. Its portfolio includes the delivery of slats, flaps, and fuselage segments for the Embraer E-Jet E1 and E2 families, as well as structural parts for the Legacy and Praetor business jet series. Beyond domestic production, the facility contributes to the global supply chain for international airframers through the wider Sonaca network. Prospective partners should verify specific certification levels for special processes, including chemical milling and surface treatments, which vary by facility. Technical due diligence should focus on the site's capacity for high-rate production of moveable wing surfaces and its compliance with both ANAC and international EASA/FAA manufacturing standards. The organisation's reliance on specific tooling for Embraer programmes should be considered when evaluating its availability for external commercial contracts.
