PISTON, LINEAR ACTUATING CYLINDER
DEPT OF DEFENSE.DEFENSE LOGISTICS AGENCY.DLA AVIATION.DLA AVIATION HUNTSVILLE.DLA AVIATION AT HUNTSVILLE, AL · Response deadline: Mon, 19 Oct 2026
What the government is buying
The Defense Logistics Agency (DLA) Aviation at Huntsville, Alabama is soliciting bids for a piston, linear actuating cylinder—a mechanical component used in hydraulic or pneumatic systems to convert fluid pressure into linear motion. These cylinders are essential parts in aircraft maintenance and support equipment, enabling controlled push-pull operations in landing gear, flight control surfaces, cargo systems, and other aviation applications.
DLA Aviation serves as the primary supply chain manager for the Department of Defense's aviation needs, procuring spare parts and components to support military aircraft readiness worldwide. The "piston, linear actuating cylinder" description suggests this is a replacement part for existing military aviation platforms rather than a developmental or prototype item.
This solicitation is unrestricted—no small business set-aside applies—meaning businesses of any size may compete.

Who can bid
Any business—small or large—may bid on this unrestricted solicitation. However, several baseline requirements typically apply for DLA Aviation contracts:
- SAM.gov registration must be active and current
- ISO 9001 or AS9100 quality certification is commonly required for aviation components; see the solicitation for specific quality system requirements
- Source of supply verification: DLA often requires proof that parts meet military specifications (MIL-SPEC) or are approved for specific aircraft platforms
- Manufacturer approval: If bidding as a distributor rather than manufacturer, authorization from the original equipment manufacturer (OEM) may be required
Because this involves an aviation-critical component, past performance with DLA, other defense agencies, or FAA-regulated markets would strengthen a bidder's position.
How to put together a competitive bid
Technical compliance first. DLA Aviation solicitations for spare parts typically reference a National Stock Number (NSN), technical drawing, or specification. See the solicitation for the exact part number, material specifications, dimensions, and performance requirements. Any deviation risks rejection.
Pricing strategy. Unrestricted DLA competitions often attract large established defense contractors. Research historical pricing for comparable NSNs through DLA's Internet Bid Board System (DIBBS) or FPDS-NG to benchmark your offer. Consider whether your firm can compete on price, delivery speed, or both.
Delivery schedule. DLA measures supplier performance rigorously through its Supplier Performance Risk System (SPRS). Proposing realistic but competitive lead times—and consistently meeting them—affects future award eligibility. See the solicitation for required delivery date and quantity.
Quality documentation. Prepare to submit material certifications, test reports, or inspection records with your bid or upon award. Aviation parts frequently require Certificate of Conformance or First Article Inspection (FAI).
