This is a new spares requirement for quantity 3 units, delivery FOB origin, with no drawings available. The Government intends to negotiate with only one source and states this notice is not a request for competitive quotes, though interested parties may identify interest and capability or submit quotes for consideration prior to award. The part requires engineering source approval by the design control activity because the approved source(s) hold data rights, manufacturing/repair knowledge, or technical data not economically available to the Government and essential to maintaining quality. An alternate source must qualify under the design control activity’s procedures approved by the cognizant Government engineering activity, and award requires the offeror, product/service, or manufacturer to meet qualification requirements at time of award under FAR 52.209-1. The Government is not using FAR Part 12 commercial-item policies, but interested parties may identify commercial-item interest and capability to the contracting officer.
