The Navy intends to procure five hydraulic accumulators on a sole-source basis from Sikorsky, as it does not own the data or rights needed to purchase the parts from other sources. Since no drawings or data are available, any firm not already approved to manufacture this item must submit a Source Approval Request (SAR), but the procurement will not be delayed for SAR approval. This notice is not a request for competitive proposals, though responsible sources may submit a capability statement or quotation for consideration. The acquisition will follow FAR Part 15 procedures and is not set aside for small businesses. Interested organizations may email their capabilities and qualifications to the contracting point of contact.
