This opportunity is for the acquisition of 82 units of a specific part (NSN 7R-1620-014752013-V2), with delivery required FOB Origin. The part is flight-critical and requires Government source approval, as only previously approved sources have been solicited due to unique design and data rights. Any new source must undergo a qualification process approved by the cognizant Government engineering activity, and award cannot be delayed for this approval. The Government intends to solicit and negotiate with only one source, but all responsible parties may submit capability statements or proposals. Proposals will be considered if received within 45 days of the synopsis publication (or 30 days under an existing BOA).
