The Air Force has issued a notice under FAR 9.2 establishing Qualification Requirements (QRs) for companies interested in manufacturing a specified item identified by NSN 2840-01-321-5571, part number 4076566, described as a Ring Segment. This notice serves as a source approval announcement rather than an indication of an imminent procurement or solicitation, meaning no purchase plans, drawings, or specifications are currently available. Interested companies must undergo a qualification process to be considered approved sources for this item. To obtain the Qualification Requirements documentation, written requests must be submitted directly to the Small Business Office at Tinker Air Force Base, with contact limited to written correspondence only via mail, fax, or email. Telephone requests are not accepted. This is strictly a sources sought notice, not a request for proposals or bids, and there is no specified issue or response date. The notice is intended to gauge and establish qualified manufacturers for potential future procurement of the specified ring segment.
