Attachment 3 - Brand Name Justification - Refueler Engine - Redacted.pdf

This is a Determination & Findings document for a sole source acquisition by the Air Force/673 Contracting Squadron/PKC for an R-11 Refueler Engine replacement.

The contracting activity seeks to procure an OEM-specified International DT466 diesel engine as a brand-name sole source item to repair an out-of-commission R11 Refueler Truck at Joint Base Elmendorf-Richardson. The 673 Logistics Readiness Squadron requires this specific engine brand to ensure direct plug-and-play installation, as the refueler chassis, engine mounts, electrical wiring, cooling system, and specialized fuel-pumping drive systems were engineered specifically for this engine model. The determination justifies the sole source action under RFO 11.204(a)(2)(ii) (Brand Name), establishing that the International DT466 brand name is essential to the Government's requirements and that market research confirms alternative manufacturers' products cannot meet the unit's minimum operational and integration needs without significant mission disruption, unacceptable vehicle downtime, and substantial retrofit and re-engineering costs that would outweigh potential cost savings. The Contracting Officer, BRENDON D. YELLOTT, SrA, USAF, signed the determination on September 16, 2026, with authority delegated under DAF Approval Authorities Matrix PM 26-C-11 and GSAR 538.7104-3(a).
