Purchase FILTER CARTRIDGE for U.S. Coast Guard Aircraft HC-27

HOMELAND SECURITY, DEPARTMENT OF.US COAST GUARD.AVIATION LOGISTICS CENTER (ALC)(00038) · Response deadline: Mon, 09 Nov 2026

What the government is buying

The U.S. Coast Guard Aviation Logistics Center is purchasing filter cartridges for HC-27 aircraft. The HC-27J Spartan is a medium-range surveillance aircraft used for search and rescue, maritime patrol, and law enforcement missions. Filter cartridges in this context typically refer to engine air intake filters or hydraulic/fuel system filtration components critical to aircraft operation and safety.

This procurement falls under NAICS code 336413 — Aircraft Manufacturing, though the work itself is procurement of a spare part rather than manufacturing. The classification code 2940 indicates Engine Air and Oil Filters, Filter Elements, and Air Intake Cleaner Filters, a Federal Supply Classification for filtration equipment.

Key facts

Who can bid

This solicitation is full and open competition with no set-aside, meaning all responsible sources may submit offers regardless of business size or socioeconomic status. Small businesses, large businesses, and non-traditional defense contractors may all compete.

Because the NAICS code 336413 carries a size standard based on employee count (typically 1,500 employees for this code), a small business interested in future Coast Guard aircraft part opportunities should verify its size status in the Small Business Administration's Size Standards Tool. However, for this specific procurement, size status does not affect eligibility to bid.

Given the specialized nature of aviation filter cartridges, potential bidders should assess whether they can supply parts meeting military aviation standards, which often require traceability, material certifications, and compliance with specific military or commercial specifications.

How to put together a competitive bid

Since no set-aside applies, price and technical compliance will likely drive award decisions. Consider these steps:

Verify technical requirements. See the solicitation for exact specifications, but expect requirements for materials of construction, dimensional tolerances, flow rates, and filtration efficiency. Aviation filters often require compliance with military specifications (MIL-PRF or MIL-DTL) or FAA-accepted parts standards.

Confirm supply chain integrity. The Coast Guard typically requires certificates of conformance, material certifications, and traceability documentation. If you are not the original manufacturer, ensure your supplier can provide complete pedigree documentation.

Evaluate past performance relevance. If you have supplied aerospace filtration products to DHS, DOD, or commercial aviation customers, highlight this experience. The Coast Guard values demonstrated reliability in aviation logistics.

Assess delivery and packaging. ALC operations depend on predictable part availability. See the solicitation for required delivery schedules, packaging specifications, and any shelf-life requirements.

Price competitively. With no small business preference, your price must compete against all responsible sources. Consider whether economies of scale in your supplier relationships can yield a cost advantage.
