Summary

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.

(a)The definitions in section 40102(a) of title 49 apply to this section.
(b)(1)The Secretary of the Treasury may—
(A)designate ports of entry in the United States for civil aircraft arriving in the United States from a place outside the United States and property transported on that aircraft;
(B)detail to ports of entry officers and employees of the United States Customs Service the Secretary considers necessary;
(C)give an officer or employee of the United States Government stationed at a port of entry (with the consent of the head of the department, agency, or instrumentality of the Government with jurisdiction over the officer or employee) duties and powers of officers or employees of the Customs Service;
(D)by regulation, apply to civil air navigation the laws and regulations on carrying out the customs laws, to the extent and under conditions the Secretary considers necessary; and
(E)by regulation, apply to civil aircraft the laws and regulations on entry and clearance of vessels, to the extent and under conditions the Secretary considers necessary.
(2)A person violating a customs regulation prescribed under paragraph (1)(A)–(D) of this subsection or a public health or customs law or regulation made applicable to aircraft by a regulation under paragraph (1)(A)–(D) is liable to the Government for a civil penalty of $5,000 for each violation. An aircraft involved in the violation may be seized and forfeited under the customs laws. The Secretary of the Treasury may remit or mitigate a penalty and forfeiture under this paragraph.
(3)A person violating a regulation made applicable under paragraph (1)(E) of this subsection or an immigration regulation prescribed under paragraph (1)(E) is liable to the Government for a civil penalty of $5,000 for each violation. The Secretary of the Treasury or the Attorney General may remit or mitigate a penalty under this paragraph.
(4)In addition to any other penalty, when a controlled substance described in section 1584 of this title is found on, or to have been unloaded from, an aircraft to which this subsection applies, the owner of, or individual commanding, the aircraft is liable to the Government for the penalties provided in section 1584 of this title for each violation unless the owner or individual, by a preponderance of the evidence, demonstrates that the owner or individual did not know, and by exercising the highest degree of care and diligence, could not have known, that a controlled substance was on the aircraft.
(5)If a violation under this subsection is by the owner or operator of, or individual commanding, the aircraft, the aircraft is subject to a lien for the penalty.
(c)(1)The Secretary of Agriculture by regulation may apply laws and regulations on animal and plant quarantine (including laws and regulations on importing, exporting, transporting, and quarantining animals, plants, animal and plant products, insects, bacterial and fungus cultures, viruses, and serums) to civil air navigation to the extent and under conditions the Secretary considers necessary.
(2)A person violating a law or regulation made applicable under paragraph (1) of this subsection is liable for the penalties provided under that law or regulation.
(d)A decision to remit or mitigate a civil penalty under this section is final. When libel proceedings are pending during a proceeding to remit or mitigate a penalty, the appropriate Secretary shall notify the Attorney General of the remission or mitigation proceeding.
(e)(1)An aircraft subject to a lien under this section may be seized summarily by and placed in the custody of a person authorized by regulations of the appropriate Secretary or the Attorney General. A report of the case shall be sent to the Attorney General. The Attorney General shall bring promptly a civil action in rem to enforce the lien or notify the appropriate Secretary that the action will not be brought.
(2)An aircraft seized under this section shall be released from custody when—
(A)the civil penalty or amount not remitted or mitigated is paid;
(B)the aircraft is seized under process of a court in a civil action in rem to enforce the lien;
(C)the Attorney General gives notice that a civil action will not be brought under paragraph (1) of this subsection; or
(D)a bond is deposited with the appropriate Secretary or the Attorney General in an amount and with a surety the appropriate Secretary or the Attorney General prescribes, conditioned on payment of the penalty or amount not remitted or mitigated.
(f)A civil penalty under this section may be collected by bringing a civil action against the person subject to the penalty, a civil action in rem against an aircraft subject to a lien for a penalty, or both. The action shall conform as nearly as practicable to a civil action in admiralty, regardless of the place an aircraft in a civil action in rem is seized. However, a party may demand a trial by jury of an issue of fact if the value of the matter in controversy is more than $20. An issue of fact tried by jury may be reexamined only under common law rules.
(g)Necessary amounts may be appropriated to allow the head of a department, agency, or instrumentality of the Government to acquire space at a public airport (as defined in section 47102 of title 49) when the head decides the space is necessary to carry out inspections, clearance, collection of taxes or duties, or a similar responsibility of the head, related to transporting passengers or property in air commerce. The head must consult with the Secretary of Transportation before making a decision on space.
