A story in Monday’s USA Today that reported the Transportation Security Administration (TSA) is working on “a massive expansion” of aviation security rules has the general aviation community on edge. Aviation groups are concerned that new security regulations could severely restrict the convenience and utility of GA aircraft. “The new security proposals must be workable and should strike the right balance between the need for security and for mobility,” NBAA v-p of communications Dan Hubbard was quoted as saying in the article. The TSA previously announced plans to require all operators of aircraft with a maximum certified takeoff weight of more than 12,500 pounds to adhere to its Twelve Five Standard Security Program, which is now limited to Part 135 operators. That proposal is now under review by the White House Office of Management and Budget. According to Michal Morgan, TSA head of GA security, government authorities are worried about terrorists transporting hazardous materials or themselves on private aircraft and/or flying them into a building.
