Crystal C Llewellyn

Crystal C. Llewellyn serves as a procurement professional specializing in aerospace and advanced communications systems acquisitions, supporting critical national defense and aviation technology programs. She manages the full lifecycle of contract actions—from market research and solicitation development to award and administration—ensuring compliance with federal acquisition regulations and mission-critical performance standards. Her work directly enables the acquisition of high-performance aircraft components, avionics systems, and mission-critical instrumentation, aligning with strategic objectives in aviation modernization and defense readiness. Llewellyn maintains a broad network of industrial partners, engaging primarily with prime contractors in aerospace manufacturing and defense electronics sectors. She cultivates collaborative relationships with both large-tier suppliers and qualified small businesses, prioritizing technical capability, past performance, and regulatory compliance over sole-source reliance. Her contracting approach emphasizes competitive bidding, robust technical evaluations, and performance-based acquisition strategies to ensure optimal outcomes for mission-critical systems. Her procurement patterns reflect a strong preference for open competition, with 88% of acquisitions conducted without set-asides. Nevertheless, she consistently supports small business participation, allocating approximately 11% of opportunities to Total Small Business Set-Asides under FAR 19.5, with minimal but intentional use of HUBZone and Women-Owned Small Business set-asides. This balanced approach ensures market diversity while maintaining access to specialized technical capabilities. Llewellyn’s primary technical focus lies in NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing) and 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), complemented by significant activity in 334511 (aeronautical navigation and guidance systems) and 334220 (radio and wireless communications equipment). She routinely procures flight control systems, radar components, embedded avionics, and secure communication modules, demonstrating deep expertise in aerospace engineering domains and defense-grade electronic systems integration.
