This is a spares procurement for a hydraulic motor used on the B-1 aircraft, with a required quantity of 15 each (minimum 4, maximum 23). The sole qualified source is Eaton Aerospace, LLC, and the government does not own the data rights, so interested firms should contact the OEM to explore manufacturing capability. The acquisition is not set aside for small business, surplus is not authorized, and the government intends to negotiate with only a limited number of sources under FAR 6.302. Required delivery is on or before April 20, 2028, and the solicitation will be issued electronically via SAM.gov. Foreign-owned firms are advised to contact the contracting officer regarding potential restrictions, and all responsible sources may submit a proposal for consideration.
