The U.S. Senate has passed a legislation package addressing many of the 9/11 Commission’s aviation security recommendations that have not yet found their way into law. Notably, the proposed rules would give the Transportation Security Administration (TSA) one year to develop a threat assessment program for general aviation airports, as well as conduct a study on the feasibility of providing grants to these airports for security upgrades. In addition, the legislation calls for increased scrutiny of passenger lists of foreign-registered GA aircraft, for screening against terrorist watch lists. The TSA would also be mandated to develop within three years a program for the screening of all cargo carried aboard passenger aircraft. The House approved its version of the legislation in January. The two bodies will now work together to negotiate differences on the bill before sending it to the White House for approval.
