Redacted_15192 - SSJ_Redacted.pdf

This is a Single Source Justification (Simplified Acquisition) form for a federal contract action. The contracting activity is OI_H/PZIMC at Hill Air Force Base, and the project involves the Balance Spindle Assembly Overhaul, identified by Purchase Request Number 15192. The estimated contract cost is redacted. The requirement involves overhauling Balance Spindle assemblies designated for Power Take Off (PTO) shafts, with each assembly requiring dynamic balancing to tight tolerances to prevent torsional vibration generation or amplification.

Collins Aerospace has been selected as the single source contractor based on proprietary design and technical data rights. Collins confirmed they have no authorized distributors or resellers for this overhaul work. The justification cites that the PTO shop at Hill AFB requires this overhaul to avoid inevitable work stoppage, and repair can only be performed through Collins Aerospace due to restricted technical data and proprietary design specifications outlined in Technical Orders TM/WI F-22-D-OO-004 and TO 16G5-5-4-3. The contracting officer determined on December 10, 2025, that only a single source is reasonably available under FAR 13.106-1(b)(1). Future market research will continue to identify alternative sources, but until Collins Aerospace agrees to sell rights to the government or a third party, all equipment must be acquired through Collins Aerospace.
