DLA Aviation is seeking market research on the capability to manufacture a source-controlled bleed air duct assembly, with an estimated five-year base period requirement. The applicable NAICS code is 336413, and the government may set aside the requirement for small businesses or pursue full and open competition, with possible multiple awards. The approved source is Arrowhead Products, and other interested contractors would need to submit a Source Approval Request since complete technical data is not available. Interested parties are invited to submit capability statements to the designated contracting contact, as this is not a solicitation or request for proposals.
