The Air Force is conducting market research via a Sources Sought notice to identify potential sources for the spares procurement of a starter valve for the B-1 aircraft, with an estimated requirement of 39 units (minimum 10, maximum 59). Interested parties must register as interested vendors; there is no solicitation available at this time. Potential sources must be capable of new manufacture, including parts procurement, inspection, testing, packaging, and shipping, and may also handle supply chain management and nonrecurring engineering costs. Performance would occur at Tinker AFB, Oklahoma. The government is interested in all business types, including small, 8(a), HUBZone, SDVOSB, and women-owned small businesses.
