DLA Aviation is conducting market research via a sources sought notice for the manufacture of a bypass indicator (NSN 2915-01-313-4615) under NAICS 336412. There is no solicitation at this time, and the government will use responses to determine whether the requirement will be set aside for small businesses or procured through full and open competition. The estimated requirement is a five-year base period with no options, and the approved source is Pall Aeropower Corp. Interested parties must submit tailored capability statements, and those other than the approved source would need to submit a Source Approval Request (SAR) package for approval. DLA Aviation does not possess complete technical data, so potential sources must be capable of furnishing labor, materials, facilities, and equipment for new manufacture including component procurement, inspection, testing, packaging, and shipping.
