Aviation Security: Actions Needed to Address Challenges and Potential Vulnerabilities Related to Securing Inbound Air Cargo: GAO Report to Congressional Requesters, May 2012

GAO was asked to examine (1) TSA actions taken since October 2010 to enhance the security of inbound air cargo transported on both passenger aircraft and all-cargo carriers; and (2) any associated challenges TSA faces. GAO reviewed relevant requirements and documents, interviewed federal officials, and visited three airports based on cargo volume. The visits provided insights, but were not generalizable to the entire industry. This is a public version of a sensitive security report GAO issued in March 2012, which also addressed U.S. Customs and Border Protection’s and TSA's use of the No Fly List to secure inbound air cargo.
