Accessory Drive Gearbox

The Defense Logistics Agency (DLA) Aviation intends to issue a Letter Request for Proposal (RFP) for the accessory drive gearbox identified by NSN 2835‑01‑208‑0169. The solicitation is a sole‑source effort directed at the Original Equipment Manufacturer, Hamilton Sundstrand Corporation (CAGE 99167), as they are the only approved source for this part. The agency will consider interest from non‑OEM sources, requesting quantities, pricing, and lead times, and may adjust the acquisition strategy if it benefits the government. The solicitation is tied to an existing Umbrella Long‑Term Contract (SPE4AX‑22‑D‑9404) and will be awarded as an add‑on to that contract. • Sole‑source solicitation aimed at Hamilton Sundstrand Corp. for a specific aircraft gearbox (NSN 2835‑01‑208‑0169). • Responses from non‑OEM vendors are allowed but must be submitted by 10/19/2026 and include capability evidence, quantity, price, and lead‑time data. • The effort is a letter solicitation; the part is covered under an existing long‑term contract, so pricing and delivery will be added to that contract’s terms.
