Title 19 › Chapter CHAPTER 4— - TARIFF ACT OF 1930 › Subtitle SUBTITLE III— - ADMINISTRATIVE PROVISIONS › Part Part VI— - Miscellaneous Provisions › § 1644a
Lets the Secretary of the Treasury pick which U.S. airports are official entry points for civil aircraft coming from other countries and make rules about those planes and the things they carry. The Secretary can send Customs officers to those ports, give other federal officers Customs duties if their boss agrees, and by rule make customs and vessel-entry laws apply to civil air travel when needed. If someone breaks those rules or public health rules that the Secretary makes apply to aircraft, the person must pay $5,000 for each violation. The aircraft can be seized and forfeited under customs law. The Secretary may reduce or cancel that penalty. If immigration or vessel-entry rules made to apply to aircraft are broken, the penalty is $5,000 and the Secretary or the Attorney General may reduce or cancel it. If a controlled drug covered by section 1584 is found on or unloaded from an aircraft, the owner or the person in command must pay the penalties in section 1584 for each offense unless they prove they did not know and, with the highest care, could not have known. If the owner, operator, or commander violated the rules, the aircraft can have a legal claim (a lien) for the penalty and may be seized. The Secretary of Agriculture can make plant and animal quarantine laws apply to civil air travel; violators face the penalties those laws provide. Decisions to reduce or cancel penalties are final. Seized aircraft are reported to the Attorney General, who must sue the aircraft or say he will not; aircraft are released when penalties are paid, court process takes them, the Attorney General declines to sue, or a bond is posted. Penalties can be collected by suing the person or the aircraft (a lawsuit against the aircraft itself). Admiralty-style procedures apply as far as possible, but a jury can be demanded for factual issues when the amount in dispute is more than $20. Agency heads may be given funds to get space at a public airport for inspections and related work after consulting the Secretary of Transportation.
