NAVSUP WSS Philadelphia intends to procure 20 aircraft screws (NSN 1R-5305-016686437-H5, P/N SS5308V1-09) on a sole source basis from Sikorsky, for delivery FOB origin. The government does not own the data or rights needed to purchase this part from other sources, and no drawings are available. Firms not already approved to manufacture this material must submit a Source Approval Request, but the procurement will not be delayed for SAR approval. All responsible sources may submit a capability statement, proposal, or quotation for consideration. This acquisition will be conducted under FAR Part 15 procedures and is not a small business set-aside.
