The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair of NIIN 016017102, a flight-critical part requiring engineering source approval. The procurement emphasizes the necessity for existing approved sources to maintain the quality of the part, as new sources must undergo a qualification process that is typically lengthy and must be completed prior to contract award. Interested parties must submit their proposals along with the required source approval documentation within 45 days of this presolicitation notice, with the understanding that the Government may proceed with award based on Fleet support needs if necessary. For further inquiries, interested vendors can contact Christian Markle at 215-697-6679 or via email at christian.markle@navy.mil.
