NAVSUP WSS Philadelphia intends to solicit on a sole-source basis with Sikorsky for repair of one drive shaft assembly (P/N 06371-05802-103; NSN 7RH 3040 016986249 H5), with delivery FOB origin. No drawings or data are available, and the Government does not own the data or rights needed to purchase the part from additional sources. Award is expected under an existing Basic Ordering Agreement, and the procurement is not a Total Small Business Set-Aside and will use FAR Part 15 rather than FAR Part 12 commercial-item procedures. Non-approved firms must submit a Source Approval Request, but the procurement will not be delayed for SAR approval; the notice is not a request for competitive proposals, though capability statements, proposals, or quotations will be considered to determine whether to compete. Electronic solicitation procedures will be used via NECO, with no telephone requests or hard copies, and interested organizations may email capabilities and qualifications to the listed Navy contact.
