Mary H Walker

Mary H. Walker serves as a Contract Negotiator responsible for managing complex procurement actions within the aerospace and defense support sector. Her role centers on ensuring compliance with federal acquisition regulations while facilitating timely, cost-effective contract awards that align with national aviation and aerospace priorities. She specializes in negotiating technical and commercial terms for high-value, mission-critical acquisitions, primarily in aircraft propulsion and auxiliary equipment systems. Her work directly supports the agency’s operational readiness by securing reliable, high-performance components essential to national airworthiness and maintenance programs. Walker’s contracting patterns reflect a strong preference for open competition, with approximately 95.5% of her awards issued under non-set-aside conditions, indicating a focus on broad market access and technical capability over socioeconomic classifications. While small business participation is limited, she consistently awards contracts under the Total Small Business Set-Aside authority (FAR 19.5), demonstrating a measured but deliberate commitment to small business engagement where market conditions permit. Her procurement focus is highly specialized, with 83.3% of her acquisitions falling under NAICS 336412 (Aircraft Engine and Engine Parts Manufacturing), and the remainder split between NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and NAICS 561499 (All Other Business Support Services). She routinely negotiates contracts for turbine components, fuel systems, avionics integration, and technical support services critical to military and civilian aviation fleets. Her domain expertise lies in engineering-intensive supply chains requiring stringent quality controls, certification compliance, and lifecycle sustainment planning. Walker works with a network of Tier 1 aerospace manufacturers and niche suppliers possessing AS9100 certification and FAA/DoD approvals. Her negotiation style emphasizes technical transparency, performance-based outcomes, and long-term vendor reliability over price alone, fostering partnerships built on compliance, innovation, and mission alignment.
