Redacted Justification and Approval.pdf

This is a Department of the Air Force Justification for Other Than Full and Open Competition (CUI) document for a Requirements Indefinite Delivery Contract (IDC) with GE Aviation Systems LLC, dba Dowty Propellers.

The Air Force Material Command (AFLCMC/WLNK Air Force Life Cycle Management Center, C-130 Division Contracting) seeks to award additional quantities of R-391 Propellers, subsystems, and components to GE Dowty under sole source justification (Purchase Request FD2060-23-30100). The requirement covers a three-year performance period consisting of a one-year Basic period and two one-year Options on a Firm Fixed Price basis. The contract will provide R-391 Propellers (NSN: 1610-99-751-8075) used exclusively on C-130J tactical airlifters, including production and delivery of propeller spares, floor-mounted kits for maintenance, and replacement parts. Two line items are specified: X001 (Propellers/Spares) and X003 (Propellers/Spares Replacement Parts, composed of multiple part numbers procured in varying quantities annually). Funding is from 3010 Procurement appropriations based on quoted prices from GE Dowty. The justification is based on 10 U.S.C. 3204(a)(1), establishing that only GE Dowty possesses the proprietary technical data, engineering design, manufacturing expertise, and certifications required to sustain C-130J operations. Alternatives would require extensive re-engineering, FAA recertification, Full Authority Digital Engine Control (FADEC) software changes, aircraft modifications, and duplication of costs estimated in the millions. Market research conducted from March 2022 through July 2024—including Small Business Administration searches, web surveys, a Sources Sought synopsis posted May 2022, and a combined synopsis/solicitation posted January 2025—yielded no viable alternative sources. No intellectual property data deliverables are required for this effort.
