This acquisition will be negotiated non-competitively under FAR 13.106-1(b)(1), which permits procurement from a single source when no other supplies or services can meet the agency's needs. The contract will support the Aerospace Ground Equipment Flight of the 1st Maintenance Squadron. The Hatz diesel engine is required due to its obsolescence as a National Stock Number (NSN), with no direct replacement available. A search for an alternative part number or NSN 4920-01-614-3132 identified only Hydraulic International Inc. as a suitable supplier. This company specializes in providing tailored, mission-specific solutions often difficult to find among multiple vendors. This notice serves as a combined synopsis/solicitation under FAR Part 13 and FAR Part 12, with NAICS code 333618 and a Small Business Size Standard of 1,500 employees. It is not a request for competitive quotes. However, capable firms are invited to submit a capability statement by 2:00 PM Eastern Time on December 23, 2025, to Erika Allen at erika.allen.2@us.af.mil. Submissions should include relevant experience and past performance. The government may consider future competitive procurement based on the responses. This is a NOTICE OF INTENT; no solicitation is currently available. Interested parties that believe they can meet this requirement are encouraged to submit a capability statement within 5 days of this posting. The statement should provide an overview of relevant services and past performance related to similar products. The award will be made through other than full and open competition, as only one responsible source can fulfill the requirement. Again, no solicitation is available at this time, and phone inquiries will not be accepted. Late submissions will not be considered. ## Publications - December 16, 2025: Special notice, due December 23, 2025 at 2:00 PM EST.
