William F Leslie

William F. Leslie serves as a procurement professional responsible for managing complex acquisitions within the aerospace and defense support sectors. He plays a critical role in executing contracting strategies that align with national security and aviation infrastructure needs, overseeing the solicitation and award of contracts for specialized technical services and aircraft component manufacturing. His portfolio emphasizes mission-critical procurements requiring high levels of technical precision and regulatory compliance, often involving classified or controlled technical data. Leslie’s work supports the operational readiness of air transportation systems and related defense capabilities through timely and compliant contract execution. His contractor relationships span a diverse ecosystem of prime vendors, including manufacturers of aircraft auxiliary equipment, aviation support service providers, and technical consulting firms specializing in aerospace engineering and legal compliance. While no single contractor dominates his portfolio, he consistently engages with firms possessing FAA certifications, ITAR compliance, and ISO 9001 accreditation. His approach favors established contractors with proven track records in defense supply chains, while actively encouraging qualified small businesses to compete for set-aside opportunities. Leslie demonstrates a strong commitment to small business participation, with approximately 25% of his awards designated as total small business set-asides under FAR 19.5. He prioritizes opportunities for small businesses capable of delivering specialized technical services and niche manufacturing capabilities, though the majority of his acquisitions remain open to full and open competition. His socioeconomic contracting patterns reflect a balanced approach—promoting competition while ensuring mission-critical requirements are met by capable, certified vendors. His primary procurement focus lies in NAICS 336413 (other aircraft parts and auxiliary equipment manufacturing), 488190 (other support activities for air transportation), and 541690 (other scientific and technical consulting services), each representing roughly 28.6% of his activity. He also regularly procures legal counsel services under NAICS 922130 to support regulatory and compliance frameworks. His expertise centers on high-complexity, low-volume procurements requiring deep domain knowledge in aviation systems, technical consulting, and federal legal procurement standards.
