Justification for Other Than Full & Open Competition

This is a Justification and Authorization (J&A) document for a Department of Navy sole-source acquisition through NAVSUP WSS–Mechanicsburg. The contracting activity seeks to procure a Hub and Cylinder Assembly (NSN 7HY 2010.0138001992, P/N 660509237) classified as spares under CLIN 23321031. The acquisition is being conducted without full and open competition under the authority of 10 USC 3204(A)(1), citing only one responsible source capable of satisfying the requirement.

The single source identified is GE Aviation Systems LLC, doing business as Dowty Propellers, Cage 93366, determined to be the only source of procurement capable of meeting the requirement. The technical advocate's market research examined multiple government databases including ITMP, FLIS, CDMD-DA, NSBDR, and ERP, finding no other sources or distributors for this item. The J&A notes that the government does not own the data or rights necessary to purchase or repair this part from alternative sources, and reversing engineer the part is deemed uneconomical. No previous J&A exists for this requirement (not previously awarded under SAT). The document has been approved at the FAR 6.304 level, with signatures from the Requirements Cognizance, Technical, Contracting Officer, Competition Advocacy, Legal Sufficiency, and Approval authority representatives dated between November 2023 and June 2025. No option percentage or specific delivery date is specified in the acquisition documentation.
