Heidi Lacosse

Heidi Lacosse serves as a secondary procurement professional within the Defense Logistics Agency Aviation, supporting the acquisition of critical aviation components essential to the readiness and sustainment of U.S. military aircraft systems. While not the primary contracting officer, she plays a vital role in facilitating the end-to-end procurement lifecycle, including requirement validation, market research, and contract administration for high-reliability parts. Her work directly enables DLA Aviation’s mission to ensure uninterrupted supply of mission-critical subsystems, particularly in the face of technical obsolescence and complex supply chain challenges. She routinely handles acquisitions for electronic components, bearings, and auxiliary aircraft equipment requiring stringent military specifications and long-term logistics support. Her contractor relationships involve a broad network of industrial suppliers, including manufacturers of avionics, electromechanical systems, and precision-engineered bearings. While no single contractor dominates her portfolio, she consistently engages with both large-tier defense suppliers and specialized small businesses capable of meeting MIL-SPEC requirements. Her interactions reflect a collaborative, compliance-driven approach, emphasizing technical qualification, quality assurance, and supply chain traceability over transactional vendor relationships. Lacosse’s procurement activity reflects a strong preference for open competition, with over 80% of acquisitions conducted without set-aside restrictions. Nevertheless, she actively supports small business participation, with approximately 15% of awards directed to total small business set-asides under FAR 19.5, and a notable 3.5% allocated to service-disabled veteran-owned small businesses. Her pattern demonstrates a balanced commitment to socioeconomic goals without compromising operational urgency or technical integrity. Her technical focus centers on NAICS 334419 (other electronic component manufacturing) and 332991 (ball and roller bearing manufacturing), reflecting deep engagement with avionics, control systems, and mechanical subsystems critical to aircraft propulsion and flight control. She also frequently procures components under 336413 for auxiliary aircraft equipment, demonstrating expertise in sourcing high-integrity, low-volume parts for legacy and next-generation military aviation platforms.
