28 -- Turbine Shaft

The contract pertains to qualification requirements for the supply of specific aircraft engine components, namely a turbine shaft and a compressor rotor used in the J85 engine, with General Electric identified as the prime contractor. Only manufacturers who are original designers or have successfully completed all required testing as stipulated by the original design authority can be considered approved sources for these components, reflecting the criticality and complexity of the parts. Access to the detailed qualification requirements is controlled and can only be obtained through a formal written request to the Small Business Office at Tinker Air Force Base. Requests via telephone are not accepted, emphasizing the importance of adherence to the established protocol. This contract is categorized as a sources-sought notice rather than a request for proposal, indicating the intent is to identify capable manufacturers rather than directly procure the item. The solicitation references National Stock Numbers for both parts: the turbine shaft (NSN 2840-01-487-3005) and the compressor rotor (NSN 2840-01-490-5272), both with specified part numbers and applications associated with the J85 engine. The document does not specify an issue or response date, nor does it provide details on set-asides or place of performance, likely reflecting its preliminary nature in vendor identification and qualification processes.
