Sensitive Security Information

This final rule strengthens the existing rules protecting sensitive security information from unauthorized disclosure. Part 191 is expanded to apply to air carriers, airport operators, indirect air carriers, foreign air carriers, and individuals, and specifies in more detail what sensitive security information they must protect. Part 191 continues to describe what information is protected from disclosure by the FAA, and describes in more detail that information. This final rule also changes part 107, 108, 109, and 129 to correspond with changes it makes to part 1991. This action is necessary to counter the increased sophistication of those who pose a threat to civil aviation and their ability to develop techniques to subvert current security measures. The intended effect of this action is to prevent undue disclosure of information that could compromise public safety if it falls into the wrong hands, while being mindful of the public's legitimate right to know and interest in aviation information.
