The Air Force is conducting market research via a sources sought notice to identify potential sources for the new manufacture spares buy of tab trim for the KC-135 aircraft, part number 527-14957-2 / NSN 1560-01-542-3037, with an estimated maximum quantity of 71 each. This is a new spares buy with no repair requirement, and interested parties must register as interested vendors to be considered participants. Performance will be at Tinker AFB, Oklahoma, and potential sources must be capable of furnishing labor, materials, facilities, and equipment for manufacturing, inspection, testing, packaging, and shipping. The government may consider breaking out the requirement by airframe and is interested in responses from large and small businesses, including 8(a), SDVOSB, HUBZone, and WOSB concerns. No solicitation is currently available, and the government will use responses to determine whether the effort can be competitive or a small business set-aside.
