28 -- Combustion Assembly Inner Liner

The Air Force has established Qualification Requirements (QRs) under FAR 9.2 for manufacturers interested in producing specific items identified by their National Stock Numbers (NSNs), Part Numbers (PNs), and nouns. Companies wishing to become approved sources for these parts must undergo a source approval process, which is separate from any immediate procurement actions. This notice does not indicate an upcoming purchase but serves to identify the Air Force’s intent to qualify potential suppliers for items including a Combustion Assembly Inner Liner, Front Turbine Bearing Support, Shaftgear, Slide, and a Lubricating Oil Tank. Interested parties must submit written requests directly to the Small Business Office at Tinker Air Force Base to receive the detailed qualification requirements and may also request technical drawings through the source approval information booklet. This announcement is designated as a sources sought notice rather than a solicitation or request for proposal, which means no bids or proposals are being requested at this time. The process ensures that only qualified manufacturers capable of meeting stringent specifications and quality standards become eligible suppliers for these components. The notice includes contact details for further information but strictly mandates written communication and disallows telephone inquiries. By establishing this pre-qualification step, the Air Force aims to streamline future procurement while maintaining rigorous production standards for critical engine components.
