The role of the Transportation Security Administration (TSA) regarding private aviation is significantly different from its role in commercial air travel. In general, passengers flying on private, non-commercial aircraft (General Aviation) do not pass through standard TSA checkpoints or undergo the "shoes-off" screening found at commercial terminals. However, this does not mean private aviation is entirely unmonitored. Under the Twelve-Five Standard Security Program (TFSSP) and the Private Charter Standard Security Program, the TSA mandates that certain charter operators conduct their own security screenings of passengers and baggage. Furthermore, the TSA has the authority to conduct "random" inspections of private hangars and aircraft to ensure compliance with security regulations. For international flights, private aircraft are subject to rigorous U.S. Customs and Border Protection (CBP) inspections upon arrival, which involve physical searches of the cabin and luggage. While the individual "private pilot" and their friends are largely exempt from the daily TSA grind, the agency maintains a background "Security Directive" framework to monitor the sector for high-level threats.
