Are iFlight Nazgul Propellers NDAA-Compliant?

iFlight is a Chinese drone company — its contact details place its headquarters in Huizhou, Guangdong, and it says it was founded in 2014 — and Nazgul propellers are iFlight's own brand, made in China. For US programs subject to NDAA covered-country flow-down requirements, which reach individual components, propellers included, that typically rules foreign-made parts like these out. Whether a specific part is permitted on a specific program depends on your contract's flow-downs, so confirm with your compliance team.

Why country of origin is the deciding factor

NDAA covered-country and flow-down requirements ban federal agencies from purchasing or operating UAS — and their components — from covered foreign entities, and they extend to federal grants, contracts, and cooperative agreements. Prime contractors flow the same requirements down to their suppliers, and compliance is required at the component level, not just the system level. Our NDAA covered-country explainer covers the mechanics.

The result: for a program under these flow-downs, the question isn't whether a propeller performs well — it's where it and its materials come from, and whether you can document that.

The practical problem: the prop comes with the airframe

Nazgul propellers ship on iFlight's own Nazgul, Chimera and Evoque platforms, so a program flying those aircraft is usually replacing the whole airframe, not just the prop. Where the prop is the line item — a Nazgul 5-inch or 7-inch tri-blade on a different frame — the question is the same as for any foreign tri-blade: which domestic part matches its diameter, pitch and blade count.

Where the line overlaps

Nazgul parts are not referenced in the Anvil line, so any match is nominal. The 5-inch and 7-inch pages list every size the line carries in those classes; send us the Nazgul part number and we'll tell you which, if any, is a drop-in candidate for your platform.
