Attachment 6 - C-5 NLG Outer Cylinder 1620-00-403-5249 Portfolio.pdf

This file is a portfolio document for a C-5 aircraft nose landing gear outer cylinder component identified by National Item Identification Number (NIIN) 1620-00-403-5249. The document serves as a technical and supply chain reference for the Landing Gear Collaborative Supply Chain Integration II initiative under the Draft RFP SPRHA1-26-R-1003, issued by the Defense Logistics Agency Aviation and the U.S. Air Force. This portfolio attachment provides detailed information about the outer cylinder component specifications, current supply chain status, and production capability data necessary for potential contractors to understand the requirements and logistics associated with this critical C-5 aircraft landing gear subassembly.

The portfolio is part of a larger pre-solicitation effort aimed at integrating and optimizing the supply chain for multiple landing gear components. As indicated in the related opportunity metadata, the Defense Logistics Agency and Air Force conducted one-on-one Q&A sessions in late March 2026 and released an updated Draft RFP with a response deadline of June 4, 2026. While only Attachments 2, 3, and 4 were revised from the previous March version, potential bidders should review this C-5 outer cylinder portfolio document to understand the specific technical, operational, and supply chain requirements that will likely be reflected in the final solicitation.
