How to Verify a Propeller Is NDAA-Compliant

"NDAA-compliant" appears on a lot of product pages. For a procurement or compliance team, the label alone isn't evidence — compliance is required at the component level, and it has specific, checkable requirements. Here is what a propeller has to satisfy, and what to ask a supplier before you put their part on a federal program.

The four requirements

  • Manufactured by a non-covered entity. The manufacturer must not appear on the FCC Covered List or be a subsidiary of a covered foreign entity — and that applies to the final assembler and all upstream suppliers.
  • No covered-entity components anywhere in the supply chain. Every sub-component, raw material, and intermediate product must be traceable to non-covered sources.
  • Full material traceability and provenance documentation. Lot numbers, material certificates, supplier declarations, and chain-of-custody records that prove compliance at every tier.
  • Manufactured in a compliant facility. The production facility must not be owned, operated, or controlled by a covered foreign entity.

A US label is not a US supply chain

The trap in component compliance is the sub-tier: a US-molded propeller using resin or reinforcement from a covered entity is not compliant. Verification has to go below the finished part — to where the polymer, fibers, and inserts came from — not stop at where it was molded or who sells it.

Questions to put to any propeller supplier

  • Where is the propeller molded, and who owns that facility?
  • Where do the resin and fiber reinforcement come from, and can you document it?
  • What traceability records ship with the part — lot numbers, material certs, supplier declarations, chain of custody?
  • Are any suppliers in the chain covered entities or subsidiaries of covered entities?

A supplier engineered for compliance should answer all four without hedging. If the answers stop at "made in the USA," keep asking.

How Anvil approaches this

Anvil Propulsion is building for these questions from day one: Nevada-based production with US-sourced materials and a domestic supply chain, and a Component Passport system in development so every propeller will ship with lot/serial traceability, material provenance records, and chain-of-custody documentation. Our compliance page lays out the full approach and its current status.

If you're replacing a specific foreign part, start from the propeller line — for example the 5×4.3×3 (HQProp 5X4.3X3 V1S replacement) or the 10×5×3 (Gemfan 1050 Cinelifter replacement)— or send us the part number on your BOM.
