Karen S Yarber

Karen S. Yarber serves as a Contracting Officer responsible for managing complex acquisitions within the aerospace and defense sector, with a primary focus on aircraft engine and engine parts manufacturing. She ensures full compliance with federal procurement regulations, overseeing the full lifecycle of contracts from solicitation through award and administration. Her work supports mission-critical capabilities for national defense and aviation systems, requiring deep technical understanding of propulsion systems, component reliability, and aerospace supply chain logistics. Yarber’s portfolio is characterized by high-stakes, technically intricate procurements that demand rigorous source selection and performance monitoring. While specific contractor names are not available, Yarber maintains relationships with a diverse range of industrial contractors, including prime manufacturers, specialized subsystem suppliers, and Tier-2/3 vendors with expertise in precision machining, turbine components, and avionics integration. Her contracting approach emphasizes performance-based outcomes, clear statement of work development, and stringent quality assurance protocols to ensure compliance with military and FAA standards. She routinely engages with vendors possessing AS9100 certification and other aerospace-specific quality management systems. Yarber’s procurement pattern reflects a strong preference for open competition, with 88.2% of her awards issued without set-aside restrictions. However, she consistently facilitates opportunities for small businesses, allocating 11.8% of her contract actions to Total Small Business Set-Asides under FAR 19.5. This demonstrates a balanced commitment to both operational efficiency and broad-based small business participation, without reliance on specialized socioeconomic programs such as 8(a), HUBZone, or SDVOSB. Her technical domain is exclusively focused on NAICS 336412, encompassing the design, development, testing, and production of aircraft engines and related engine components. She specializes in procuring high-performance turbine systems, fuel control units, exhaust assemblies, and maintenance-supporting spare parts, requiring deep familiarity with aerospace engineering standards, life-cycle sustainment, and defense logistics frameworks.
