About this opportunity
The Defense Logistics Agency Aviation issued a Justification for Other Than Full and Open Competition (Form S53) on February 4, 2026, for the sole source acquisition of adapter splines (NSN 3040-01-551-3579) used in UH-60A, UH-60L, and UH-60V helicopters. The acquisition involves 774 units of these mechanical power transmission components procured on a firm fixed-price basis against a Basic Ordering Agreement. Sikorsky Aircraft Corporation (CAGE 78286) was selected as the sole source supplier based on statutory authority 10 U.S.C. 3204(a)(1), citing acquisition from the original manufacturer for a subsequent time and the unavailability of technical data to enable competitive acquisition, as the manufacturer declined to license data rights to the Government. The contract SPE4A122G0005 was awarded on September 17, 2025, with an anticipated value exceeding $750,000 but not exceeding $15,000,000, as reflected in the Competition Advocate approval level. Although a sources sought notice generated limited interest and no market survey was conducted, the Defense Logistics Agency identified future actions to promote competition, including preparation of a Federal Business Opportunities synopsis and incorporation of procurement notes for competitive consideration in subsequent solicitations.
