The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking to procure aircraft door replacement parts under a presolicitation notice. The procurement involves the acquisition of two units of a specific National Stock Number (NSN 7R-1560-017060932-RQ) item, which is critical for flight operations and requires government source approval prior to contract award. This sole-source procurement emphasizes the importance of the item, as complete technical data is not available, and only previously approved sources will be solicited. Interested vendors must submit capability statements and adhere to the requirements outlined in the NAVSUP Source Approval Information Brochure, with inquiries directed to Nadia Govorushko at nadia.govorushko@navy.mil.
