What the government is buying

The Defense Logistics Agency (DLA) Aviation is procuring a turbine engine segment—a component used in aircraft turbine engines. The item falls under Federal Supply Classification (FSC) code 28, which covers engines, turbines, and components. This is a procurement for a specific aircraft part rather than a full engine or overhaul service.

Turbine segments are critical components in gas turbine engines, typically forming part of the hot-section assembly that must withstand extreme temperatures and rotational stresses. These parts require precision manufacturing to aerospace specifications and often involve specialized alloys or coatings. See the solicitation for exact technical requirements, quantities, and any approved sources or technical data packages.

Key facts

Who can bid

This solicitation is unrestricted—any qualified business, including small and large businesses, may compete. There is no small business set-aside indicated. The relevant NAICS code is 336412 (Aircraft Engine and Engine Parts Manufacturing), which carries a Small Business Administration size standard of 1,500 employees.

To compete, a firm typically needs:

• Experience manufacturing or supplying aerospace turbine components to military or commercial standards
• Approved quality systems (commonly AS9100/ISO 9001 and NADCAP for special processes)
• Ability to meet DLA's technical and traceability requirements for aviation parts
• Active SAM.gov registration and proper CAGE code

If you are a small business in this NAICS, you are not reserved an advantage but face no exclusion either. Consider whether your firm can meet any source approval, testing, or first-article inspection requirements that DLA typically imposes on critical aerospace items.

How to put together a competitive bid

Review technical drawings and requirements carefully. Turbine segments are not commodity items; dimensional tolerances, material specifications, and surface treatments are tightly controlled. See the solicitation for the exact technical data package, specification, and whether the government provides a technical data license.

Verify your manufacturing capability against the required specification. Common military specifications for turbine components include MIL-S-5002 (surface treatments) or engine-specific technical orders. If you lack direct experience with the exact part number, determine whether reverse engineering or subcontracting a portion of the work is permissible and practical.

Check for Qualified Products List (QPL) or Qualified Manufacturers List (QML) requirements. Many DLA FSC 28 items require pre-qualification. See the solicitation for any such requirement and whether an alternate source approval process is available.

Price strategically. Research historical procurement data on FPDS.gov or SAM.gov for this NSN or similar turbine segments. Factor in raw material lead times for nickel-based superalloys or specialized forgings, which can extend beyond standard delivery schedules.

Submit through DLA's electronic systems. The solicitation likely requires submission via DLA Internet Bid Board System (DIBBS) or as directed in the full notice. Ensure your SAM.gov registration is current and matches your offeror identity exactly.

Next steps

Read the full solicitation on SAM.gov using solicitation number SPE4A127T0164. Confirm all technical requirements, quantity, delivery schedule, and any packaging or marking specifications. Note the firm response deadline of October 26, 2026—with the notice posted October 18, 2026, you have limited time to evaluate and prepare your bid. Submit questions through the designated contract specialist early if any requirement is unclear.
