How to bid on aircraft replacement parts for the Department of Defense
What the agency is buying
The Department of Defense is seeking three units of a specific aircraft replacement part, NSN 6625-01-573-4589. This part is considered flight-critical. The delivery terms are FOB origin. This is a Request for Information (RFI), which means the agency is gathering information and may not lead to an immediate contract award, but it is an important step for potential vendors.
The government currently lacks sufficient technical data to purchase this part from new sources without prior approval. Only previously approved sources were directly solicited for this RFI.
Key dates and deadlines
This RFI was published on August 07, 2026. The deadline for responses is September 21, 2026, at 12:00 AM ET. All required information must be submitted by this deadline.
If you are not an approved source, the time required for source approval may mean an award cannot be delayed. However, submitting your approval information with your offer is crucial for consideration.
Who this opportunity suits
This opportunity is primarily for firms that are already approved sources for flight-critical aircraft parts, specifically those related to NSN 6625-01-573-4589. However, it also suits manufacturers who can produce this type of equipment and are willing to go through the source approval process with NAVSUP Weapon Systems Support (NAVSUP WSS).
Companies specializing in aircraft equipment and replacement parts, particularly those with experience in flight-critical components, will find this relevant.
How to respond
To access the opportunity, click on "View original source" on the portal. If the first click takes you to the homepage, click it again to go directly to the bid. You may need a free account on the portal to view all documents, though this is not always required.
If you are not an approved source, you must submit the detailed information outlined in one of the NAVSUP WSS Source Approval Information Brochures along with your proposal. If your source approval request is already being evaluated, include a copy of the cover letter from your previous submission. Offers that do not include all required data for source approval will not be considered.
Tips for a competitive response
Carefully review the NAVSUP WSS Source Approval Information Brochures to understand all requirements for new sources. Ensure every piece of requested data is included in your submission, as incomplete offers will not be considered. Even if approval may not be finalized by the award date, demonstrating your capability and initiating the approval process is essential.
Clearly articulate your company's experience in producing the same or similar flight-critical items. Provide comprehensive technical data to support your manufacturing capabilities. If you have never made this specific item, be prepared to submit the technical data required for new manufacturers as specified in the brochure.
