Why 49 U.S.C. § 46506 Matters If You Are Under Investigation

If you are accused of assault, sexual abuse, theft, robbery, or another serious offense that allegedly occurred aboard a commercial or private aircraft, the federal government may have authority to prosecute you under 49 U.S.C. § 46506. This statute takes criminal laws that normally apply on federal land or in federal buildings and extends them to aircraft within the “special aircraft jurisdiction” of the United States. The consequences are very real: a federal conviction for assault aboard an aircraft carries the same sentencing ranges as an assault committed inside a federal courthouse, and a sexual abuse charge on a flight is prosecuted under the same chapter 109A provisions that apply on military installations.

Many people do not realize that federal jurisdiction can attach the moment the cabin doors close, even before the aircraft leaves the gate. Are you being investigated for a federal crime that happened on an airplane?  Contact the Denver federal criminal defense team at Evergreen Attorneys today at (303) 948-1489 for a confidential case evaluation.

What 49 U.S.C. § 46506 Does: Plain-English Definition

49 U.S.C. § 46506 is a jurisdictional bridge law. It does not create any new criminal offenses (crimes). Instead, it takes existing federal criminal laws, known as enclave offenses under Title 18 of the United States Code, and makes them enforceable on aircraft that fall within the “special aircraft jurisdiction” of the United States. More on that below.

Specifically, the statute provides that if a person commits a crime on a qualifying aircraft that would violate certain sections of the criminal code when committed within the special maritime and territorial jurisdiction (defined by 18 U.S.C. § 7), that person may be fined, imprisoned, or both under those provisions. The statute also incorporates a District of Columbia public order offense (D.C. Code § 22-1112) for certain disorderly conduct crimes aboard aircraft.

In practical terms, this means the federal government can charge a passenger or crew member with a federal felony or misdemeanor for conduct that took place entirely inside an aircraft cabin, provided the jurisdictional requirements are met.

Essentially, this law gives the federal government the ability to punish run-of-the-mill crimes like assault, disorderly conduct, drunken behavior, indecent exposure, and other violent acts which take place on a U.S.-based commercial flight.

How Special Aircraft Jurisdiction Works

The phrase “special aircraft jurisdiction of the United States” is defined in 49 U.S.C. § 46501(2) and further explained in the DOJ Justice Manual section on special aircraft jurisdiction of the United States. The jurisdiction covers:

• U.S. civil aircraft while in flight
• U.S. military aircraft at any time
• Aircraft of any nationality that depart from or arrive at a place in the United States, while outside the United States
• Certain foreign aircraft with a next scheduled destination or last point of departure in the United States

The “in flight” definition is broader than most people expect. An aircraft is considered “in flight” from the moment all external doors are closed after embarkation until one such door is opened for disembarkation. In the event of a forced landing, the aircraft remains “in flight” until competent authorities take responsibility. This means that federal jurisdiction under § 46506 can attach while the plane is still on the ground, taxiing to the runway with the cabin doors sealed.

Evergreen Attorneys won 9-0 in the U.S. Supreme Court in United States v. Hemani in June 2026, demonstrating the firm’s ability to litigate complex jurisdictional and constitutional questions at the highest level of federal practice.

Enclave Offenses Applied to Aircraft Under § 46506

The enclave offenses cross-referenced by 49 U.S.C. § 46506 carry the same penalties they would if committed on federal land. These include:

• Assault (18 U.S.C. § 113): Ranges from simple assault (misdemeanor) to assault with intent to commit murder (up to 20 years)
• Maiming (18 U.S.C. § 114): Up to 20 years of imprisonment
• Theft of property (18 U.S.C. § 661) and receiving stolen property (18 U.S.C. § 662)
• Murder (18 U.S.C. § 1111), manslaughter (18 U.S.C. § 1112), and attempted murder or manslaughter (18 U.S.C. § 1113)
• Sexual abuse offenses (18 U.S.C. chapter 109A): Including aggravated sexual abuse, which carries a mandatory minimum of 30 years under certain circumstances

Robbery under 18 U.S.C. § 2111 is also included. The statute additionally incorporates the D.C. public order offense for certain disorderly acts aboard aircraft.

Sentencing for these offenses follows both the statutory maximums of the underlying provision and the United States Sentencing Guidelines. A conviction for a violent offense aboard an aircraft may also trigger additional sentencing enhancements.

What Happens During an Investigation for Federal Crimes on Airplanes

Federal investigations arising from alleged crimes committed on aircraft in flight typically follow a distinct pattern. Airlines, flight crews, or airport law enforcement generate an initial incident report. That report may be referred to the FBI or another federal agency. From there, the U.S. Attorney’s Office evaluates whether the aircraft was within the special aircraft jurisdiction and whether the alleged conduct fits an underlying enclave offense.

The investigation may involve interviews of crew members and passengers, review of in-cabin surveillance footage and airline records, examination of the aircraft’s flight data and door logs, and coordination with foreign law enforcement if the aircraft or passengers have international connections. If the U.S. Attorney’s Office decides to prosecute, charges are filed in United States District Court, and the case proceeds through an initial appearance, a potential federal detention hearing, discovery, motions, and potentially trial.

Because jurisdiction under § 46506 depends on technical questions about the aircraft’s registration, route, and door status, these cases often present defensible issues that require careful analysis by experienced federal criminal defense attorneys.

Steps to Take If You Are Facing Federal Charges for Conduct on an Airplane

If you have been contacted by federal agents, arrested at an airport, or learned that you are the subject of an investigation for conduct aboard an aircraft, take the following steps:

1. Exercise your right to remain silent. Do not provide a statement to FBI agents, airline investigators, or airport police without an attorney present. Anything you say can be used to establish the elements of an enclave offense.
2. Retain a federal criminal defense attorney immediately. Aircraft jurisdiction cases involve specialized legal questions that general criminal defense attorneys may not handle regularly. Contact counsel before your initial appearance.
3. Preserve all evidence in your possession. Save boarding passes, receipts, text messages, and any communications related to the flight. Do not delete digital evidence.
4. Do not contact witnesses, crew members, or other passengers about the incident. Any contact could be characterized as obstruction or witness tampering.
5. Request and review the government’s evidence early. Your attorney should seek flight manifests, airline incident reports, surveillance footage, and door-closure records to evaluate whether the jurisdictional requirements of § 46506 are actually met.

How Evergreen Attorneys Can Help

Evergreen Attorneys is a federal criminal defense boutique that exclusively handles federal criminal defense cases. This includes cases that turn on specialized jurisdictional frameworks like the “special aircraft jurisdiction” of the United States. Founding Partner Zachary Newland has appeared as counsel of record in more than 130 federal cases since 2016.

For cases arising under 49 U.S.C. § 46506, the firm can analyze whether the special aircraft jurisdiction requirements are satisfied, evaluate the elements of the underlying 18 U.S.C. enclave offense, challenge the sufficiency of the government’s evidence regarding the aircraft’s status and the defendant’s conduct. Because these cases often involve federal criminal defense for international air travelers and cross-border jurisdictional questions, Evergreen Attorneys’ focus on federal practice provides a direct advantage over firms that handle federal cases as a sideline to state criminal work.

Frequently Asked Questions

What does 49 U.S.C. § 46506 mean for crimes committed aboard an airplane in flight?

49 U.S.C. § 46506 applies certain existing federal criminal laws to acts committed aboard an aircraft within the special aircraft jurisdiction of the United States. The statute does not create new offenses. Instead, it extends the reach of specific enclave offenses found in Title 18, including assault (18 U.S.C. § 113), maiming (18 U.S.C. § 114), theft (18 U.S.C. § 661), murder and manslaughter (18 U.S.C. §§ 1111, 1112, 1113), sexual abuse (18 U.S.C. chapter 109A), and robbery (18 U.S.C. § 2111), to conduct occurring on qualifying aircraft. If the special aircraft jurisdiction test is met, a person can be fined, imprisoned, or both under these provisions.

When is an airplane considered “in flight” for purposes of federal jurisdiction?

Under Department of Justice guidance on special aircraft jurisdiction, an aircraft is “in flight” from the moment all external doors are closed after embarkation until one such door is opened for disembarkation. In a forced landing scenario, the aircraft remains “in flight” until competent authorities assume responsibility. This definition means federal jurisdiction can attach while the aircraft is still on the ground with the doors sealed, during taxiing, departure, cruise, and arrival. The key factor is door status, not whether the aircraft is airborne.

What kinds of penalties apply for a conviction under 49 U.S.C. § 46506?

Penalties are governed by the underlying criminal statute that the conduct would violate within the special maritime and territorial jurisdiction. For example, assault under 18 U.S.C. § 113 ranges from a misdemeanor for simple assault to up to 20 years for assault with intent to commit murder. Sexual abuse offenses under chapter 109A can carry mandatory minimum sentences. Sentencing in federal court also considers the United States Sentencing Guidelines, the defendant’s criminal history, and case-specific factors. The D.C. public order offense incorporated by § 46506 carries its own, separate penalty structure.

Can the federal government prosecute crimes committed on foreign airplanes under this statute?

The special aircraft jurisdiction of the United States, as defined in 49 U.S.C. § 46501(2), extends to aircraft that depart from or are destined for a place in the United States, regardless of the aircraft’s nationality. This means that if a foreign-registered aircraft departs from or arrives at a U.S. airport, conduct aboard that aircraft may fall within federal jurisdiction. The specific jurisdictional test depends on the aircraft’s registration, route, and the timing of the alleged offense relative to the “in flight” period.

When should a person facing allegations of criminal conduct on an airplane contact federal defense counsel?

Contact a federal criminal defense attorney as soon as you become aware of any federal interest in your conduct aboard an aircraft. This includes receiving a call from an FBI agent, being detained at an airport after a flight, learning that airline security filed a report, or receiving any written communication from a U.S. Attorney’s Office. The jurisdictional and evidentiary issues in cases under 49 U.S.C. § 46506 are complex, and early involvement of counsel can shape how the investigation proceeds, whether charges are filed, and how defensible issues are preserved for federal defense resources and potential trial.
