The Government requires 208 EA of NSN 7R-1650-016221417-QF (TDP VER 001), delivered FOB origin. The part requires engineering source approval by the design control activity; approved sources retain necessary data rights, manufacturing/repair knowledge, or technical data not economically available to the Government. An alternate source must qualify under design-control-activity procedures approved by the cognizant Government engineering activity. The Government intends to solicit and negotiate with only one source under FAR 6.302-1, though responsible sources may identify interest and capability; this is not a request for competitive proposals. Drawings are not available, while Military/Federal specifications, standards, QPLs/QPDs, handbooks, and other standardized documents can be obtained through DODSSP/DAPS in Philadelphia, PA or ASSIST-Online.
