This is a market research request to identify sources capable of overhauling the C-130 Cargo Winch for the USAF and USN. The work includes a full range of maintenance, engineering support, and obsolete parts resolution, and must be performed to strict military specifications. The Government notes it does not own the necessary technical data or rights for the overhaul, and that obtaining them has been deemed uneconomical. No specific budget, performance location, or non-bid timelines are detailed in this description.
