The requirement is for 265 units of NSN 3H-3110-009873734-NT under TDP version 019, delivered FOB origin. The part requires engineering source approval by the design control activity, and approved sources retain essential data rights, manufacturing/repair knowledge, or technical data, so alternate sources must qualify through Government-approved procedures. Interested parties may obtain military/federal specifications, standards, QPLs, QPDs, handbooks, and other standardized documents from DODSSP/DAPS; patterns, drawings, deviation lists, and purchase descriptions are not stocked there, and many documents are available via ASSIST-Online. The Government is not using FAR Part 12 commercial-item policies for this acquisition, but interested parties may identify commercial-item interest and capability to the contracting officer.
