NSN: 2840-01-308-4467NZ P/N: 4070107 Noun: Liner, Augmentor

The solicitation SPRTA1-26-R-0124, issued by the Defense Logistics Agency Aviation office at Tinker Air Force Base, Oklahoma, seeks procurement of a Linear Augmentor liner (NSN 2840-01-308-4467NZ, P/N 4070107) for the F-100 engine. The item is made of a Columbium Alloy, and the presolicitation was posted on December 8, 2025, with a response deadline of January 26, 2026. The acquisition is governed under NAICS code 336412, which corresponds to aircraft engine and engine parts manufacturing. This presolicitation focuses on a Source Approval Request (SAR) process rather than a traditional sealed bid or competitive negotiation, emphasizing stringent technical qualification, manufacturing documentation, and compliance standards over pricing details, with no contract value or pricing data disclosed. Potential sources must comply with detailed Manufacturing Qualification Requirements for propulsion-related Critical Safety Items (CSI) and Critical Application Items (CAI), including stringent engineering and procedural documentation, process control, and traceability. The submission package consists of numerous delineated elements (Elements A through M), covering corporate profiles, engineering data, manufacturing plans, licensing agreements, inspection data, sub-tier supplier certifications, and demonstration production documents. Proposals require comprehensive documentation of production processes, tooling certifications, and quality compliance to standards such as AS9100, ISO 9001, and NADCAP, with all manufacturing activities fully traceable and auditable. Packaging and preservation must meet applicable military standards to ensure delivery integrity. Inspection and acceptance responsibilities rest jointly with the contractor and government engineering activities, with final acceptance based on evaluation of submitted documentation and potential on-site audits. Submissions must be electronically delivered in approved formats (unencrypted PDFs on specified media or government transfer systems) according to procedures outlined on SAM.gov and DIBBS. Special contract requirements include license agreements confirming rights to proprietary data, letters of support from any proprietary sub-tier suppliers, and certifications for master tooling to ensure manufacturing asset control. The evaluation framework appears compliance-based and qualitative, likely employing a Lowest Price Technically Acceptable methodology, although explicit award criteria or weighting are not provided. The contract is functionally structured to ensure high reliability and manufacturability of propulsion-critical components integral to the F-100 engine fleet sustainment.
