MARY ANN SINDE

Mary Ann Sinde specializes in the precision manufacturing of mission-critical aircraft components and sealing systems for defense applications. Their core capabilities include the production of specialized tooling such as taper pins and tie rod assemblies, alongside high-integrity gaskets and sealing devices that ensure operational reliability in extreme environments. The contractor demonstrates deep technical expertise in aerospace-grade material fabrication, precision machining, and assembly of auxiliary equipment compliant with military specifications. Their ability to deliver small-batch, high-accuracy components—often for legacy or classified platforms—positions them as a trusted supplier for mission-essential parts requiring stringent quality control and rapid turnaround. The contractor maintains a consistent and exclusive relationship with the Department of Defense, supplying engineered components across multiple platforms, including avionics systems, propulsion interfaces, and structural assemblies. All awarded contracts are defense-focused, indicating a narrow but highly specialized niche supporting aircraft maintenance, overhaul, and modernization programs. Their work supports sustainment efforts for both current and aging military aerospace systems, demonstrating adaptability to evolving technical requirements within DoD supply chains. Primary industry focus lies in Other Aircraft Parts and Auxiliary Equipment Manufacturing (NAICS 336413), where they deliver custom tools and hardware integral to aircraft assembly and repair. Secondary involvement in Gasket, Packing, and Sealing Device Manufacturing (339991) underscores their capability in fluid and pressure containment systems critical to aerospace and defense applications. Though occasional awards fall under wholesale distribution (424490), these appear to reflect administrative or logistical channels rather than core manufacturing activity, with the contractor’s true value rooted in precision fabrication. As a Women-Owned Small Business and Woman-Owned Business certified entity based in Mobile, Alabama, Mary Ann Sinde operates as a nimble, agile supplier within the federal aerospace supply base. Their certifications enhance access to set-aside programs, while their geographic location supports proximity to key defense manufacturing and logistics hubs in the Gulf Coast region.
