Carriage of Narcotic Drugs

FAR 91.19 Carriage of Narcotic Drugs

FAR 91.19 prohibits operating a civil aircraft in the U.S. with knowledge that narcotics, marijuana, or depressant/stimulant drugs are aboard. Read the rule.

In Plain English

FAR 91.19 prohibits operating a civil aircraft within the United States if you know that narcotic drugs, marijuana, or depressant or stimulant drugs or substances (as defined by federal or state law) are being carried onboard.

The key elements are:

  • Civil aircraft only — the rule applies to civil operations within U.S. airspace.
  • Knowledge requirement — the violation hinges on the operator knowing the prohibited substances are aboard.
  • Substances covered — narcotics, marijuana, and depressants or stimulants as defined in federal or state statutes.

There is one important exception: the prohibition does not apply when the carriage is authorized by or under any federal or state statute, or by any federal or state agency (for example, lawful transport by law enforcement or a licensed medical shipment).

Why it matters: a violation can cost you your pilot certificate, expose you to criminal prosecution, and lead to aircraft seizure. Pilots flying charter, charity, or even friends should ask reasonable questions about cargo and baggage to avoid unknowingly running afoul of this rule.
