48--BODY,VALVE

The contract involves the procurement of 200 units of a specific valve body (NSN 7R-4810-015919739-GF, TDP VER 002) with delivery terms FOB origin. This item is classified as flight critical and requires strict engineering source approval by the design control activity to ensure quality maintenance. The acquisition or repair of the part must be from sources previously approved by the Government, as these sources possess unique design capabilities, specialized engineering skills, and critical manufacturing or repair knowledge. This proprietary data is essential for maintaining the quality of the part and is not economically available to the Government for open competition. If an alternate source wishes to qualify, it must undergo a qualification process approved by the relevant Government engineering authority, following procedures that typically do not allow award delays to accommodate new source approval. The Government intends to solicit and negotiate exclusively with the currently approved source(s) under FAR 6.302-1 and only considers proposals that include all necessary data or documentation for source approval as per NAVSUP Weapon Systems Support guidelines. Proposals missing required data will not be considered. Interested parties not already approved must submit detailed technical data consistent with their experience or history with similar items. Responses to this solicitation will be accepted through March 9, 2026, but the Government retains discretion over competition and may proceed with award to support fleet needs without delay. The contracting office handling this action is the Defense Logistics Agency Aviation in Philadelphia, with Ashley Walters as the primary contact for inquiries.
