The Air Force is conducting market research to identify potential sources for the spares procurement of a combustion clamp (NSN 6615-01-276-8318, P/N 4030468-907), with an estimated requirement of 28 units. This is a sources sought notice only, not a solicitation, and no contract will be awarded based on this market research. Interested parties must register as interested vendors to participate. The government is interested in all business types, including small, disadvantaged, 8(a), service-disabled veteran-owned, HUBZone, and women-owned small businesses, and may consider breaking the requirement out by airframe. Performance of services would be at Tinker AFB, Oklahoma.
