I want to bring a gift to my buddy in Russia, and he's very much into aviation, so I found a defective aluminum Cessna propeller for him. It fits the luggage and the airline accepts it, but I'm worried if I can export it from the US. It's going to have a tag from tech inspection that it cannot be used on a certified aircraft due to some wear on a blade. Local FAA office doesn't take phone calls, probably due to the government shutdown. How is this regulated? Can I carry out it as a souvenir?
I have read in several places that high tech US production such as aircraft, engines, propellers and their blades are subject to export regulation, but the only definite thing I found so far is airworthiness certification of the FAA.
EDIT: My concerns are because of this: https://www.faa.gov/aircraft/air_cert/international/export_aw_approval/export_aw_process/ and this: https://www.faa.gov/aircraft/air_cert/international/export_aw_approval/media/8130-3QA.pdf
EDIT 2: CBP is able to answer this question, they have an item in their help phone line's automated menu about goods that are possible to be under export regulations, but they aren't working these days. https://www.cbp.gov/contact
