Mini Mutes Gear Assembly, Speed

This justification documents a sole‑source procurement for fifteen units of a proprietary Azimuth Drive Gearbox (NSN 3010‑01‑315‑5148, PN 137474‑101). The Defense Logistics Agency Weapons Support determined that only Daltron Advanced Technologies (division of Fisica Applied Technologies) possesses the necessary engineering data and manufacturing capability, and no other qualified sources were identified despite market research and an industry day. • The part is a unique, high‑reliability gear assembly required for defense aircraft; the data is proprietary and the contractor has not agreed to share it. • Market research included an industry day (August 2025) and a sources‑sought notice posted 20 April 2026; no responses were received. • The contract is a Firm‑Fixed‑Price award with a quantity of 15 units; no options or extensions are planned.
