Rosa Tyiska

Rosa Tyiska serves as a primary procurement lead within the ASC Supplier Operations OEM Division of the Defense Logistics Agency Aviation, where she manages critical acquisitions of high-reliability components essential to U.S. military aircraft systems. Her role centers on securing precision-engineered parts for propulsion, flight control, and avionics subsystems, ensuring mission readiness and supply chain resilience for both legacy and next-generation platforms. She handles complex, technical contracts requiring stringent compliance with military specifications and aerospace quality standards, often coordinating with engineering and logistics teams to align procurement with operational requirements and sustainment timelines. Rosa maintains strategic relationships with a broad base of industrial suppliers specializing in aerospace-grade manufacturing, including firms with AS9100 certification and DoD-qualified vendor status. While no single contractor dominates her portfolio, her contracting patterns reflect a preference for vendors with proven track records in producing mission-critical components under tight tolerances and rigorous inspection protocols. She engages with both large-tier OEMs and specialized niche manufacturers capable of meeting exacting military performance and traceability requirements. Rosa’s procurement activity is entirely non-set-aside, with 100% of her acquisitions conducted under full and open competition. This reflects the technical specificity and low supplier base for the high-reliability components she procures, where only a limited number of qualified vendors meet the stringent performance and certification thresholds required for aviation systems. While small business participation is not formally prioritized through socioeconomic set-asides, she remains open to qualified small businesses that demonstrate technical capability and compliance with defense manufacturing standards. Her primary focus lies in NAICS 334512 and 334519, encompassing automatic environmental control systems and precision measuring and controlling devices used in aircraft cabins and flight systems. She also procures industrial process control instrumentation (334513) and auxiliary aircraft components (336413), demonstrating deep expertise in thermal regulation, sensor integration, and avionics interface systems critical to aircraft safety and operational performance.
