DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA AVIATION.DLA AV RICHMOND.DLA AVIATION · Response deadline: Mon, 26 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA) Aviation is procuring shackles—a common type of rigging hardware used for lifting, securing, and connecting loads. Shackles are U-shaped metal pieces with a pin or bolt across the opening, widely used in industrial, marine, and aerospace applications for their strength and reliability. In a defense aviation context, shackles typically support maintenance, ground handling, or cargo operations where secure fastening is critical.
This is a combined synopsis/solicitation, meaning the notice serves as both the announcement of the requirement and the actual solicitation document. Vendors should treat this as a binding opportunity to submit offers.

Who can bid
This is an unrestricted solicitation with no small-business set-aside, meaning businesses of any size may compete—including large manufacturers, small businesses, and nontraditional defense contractors. The NAICS code 336413 corresponds to "Other Aircraft Parts and Auxiliary Equipment Manufacturing," which covers a broad range of aerospace hardware including shackles and similar fastening components.
To bid, your firm should have:
- Capability to manufacture or supply shackles meeting DLA's technical and quality specifications
- Experience with defense or aerospace supply chains, including familiarity with military standards (MIL-SPEC) and quality systems
- Ability to deliver against DLA Aviation's ordering and distribution requirements
Small businesses without prior DLA experience are not barred from competing, but should be prepared to navigate DLA's procurement systems and any applicable technical qualifications.
How to put together a competitive bid
Understand the technical requirements. Shackles for defense use typically must meet specific military standards for material, load rating, finish, and traceability. See the solicitation for exact specifications, testing requirements, and inspection criteria.
Verify your NAICS alignment. While 336413 is broad, ensure your primary business activities and past performance align with aircraft parts manufacturing or distribution. Misalignment can raise questions during evaluation.
Price competitively for indefinite-delivery contexts. DLA often awards contracts with estimated quantities rather than firm orders, with pricing based on how competitive your rates are against historical benchmarks. Research DLA's historical shackles pricing through SAM.gov contract data if available.
Confirm your manufacturing and delivery capacity. DLA Aviation operates on rapid fulfillment timelines for critical aviation spares. Be realistic about lead times for raw materials, plating or coating processes, and any subcontracted testing.
Register and maintain required systems. Ensure your firm is registered in SAM.gov with active status, and that you can receive electronic orders and submit invoices through the appropriate DLA systems.
