Title 49 › Subtitle SUBTITLE VII— AVIATION PROGRAMS › Part A— AIR COMMERCE AND SAFETY › Subpart iii— safety › Chapter 449— SECURITY › Subchapter I— REQUIREMENTS › § 44905
TSA must make rules that require airlines, airports, ticket agents, and their workers to quickly tell the TSA when they learn about a threat to civil aviation, unless the message came from the U.S. government. If TSA decides the threat cannot be handled so that passengers and crew are safe, TSA must cancel the flight or flights. The President must make rules about when to warn the public about threats. Those rules must name who decides whether to warn people, who makes sure warnings go out quickly (including a toll-free phone number), and who can cancel flights. The rules must say to consider how specific and credible the threat is, whether it can be stopped, protecting intelligence sources, whether canceling is better than alerting the public, whether travelers and crew can take steps to reduce risk after a warning, and other relevant factors. TSA must also make rules to warn flight and cabin crews when needed, limit who can see threat information (without stopping needed security work), and share the guidelines with the Departments of Transportation, State, Justice, and air carriers.
