The Air Force is conducting market research to identify potential sources for the spares procurement of a Frame, Access Hole Platform (NSN 1560-01-468-7510FW, P/N DAA3144A671-067) for the B-2 aircraft. Performance will be at Tinker AFB, Oklahoma, and the requirement is for the new manufacture of one unit with no repair requirement. This is a sources sought notice, not a solicitation, and no contract award will result from this market research; interested parties must register as interested vendors and provide requested business information. Potential sources must be able to supply all labor, materials, facilities, and equipment for manufacturing, and must complete a Source Approval Request (SAR) package to meet qualification requirements, with no guarantee of government-provided technical data. All business types are encouraged to participate, including small, small disadvantaged, 8(a), service-disabled veteran-owned, HUBZone, and women-owned small businesses.
