Title 49 › Subtitle SUBTITLE VII— - AVIATION PROGRAMS › Part PART A— - AIR COMMERCE AND SAFETY › Subpart subpart iii— - safety › Chapter CHAPTER 449— - SECURITY › Subchapter SUBCHAPTER I— - REQUIREMENTS › § 44905
The TSA must make rules so airlines, airports, ticket agents, and their employees promptly tell the TSA when they get information about a threat to civil aviation (unless the notice came from the U.S. government). If the TSA decides a specific threat cannot be handled so passengers and crew are safe, the TSA must cancel that flight or series of flights. The President must make rules about when to warn the public and who decides that, how to give timely notice (including a toll-free number), and who can cancel flights. The rules must consider things like how specific and credible the threat is, whether it can be stopped, protecting intelligence sources, canceling flights instead of public warning, and whether people can reduce their risk after a warning. The TSA must also make rules to notify flight and cabin crews, may warn only certain travelers if the threat applies only to them, limit who can see threat information without blocking security duties, and share these rules with DOT, State, Justice, and air carriers.
