In 2007,TSA began deploying advanced imaging technology to screen airline passengers for weapons, explosives, and other concealed objects. In 2009 and 2010, TSA used American Recovery and Reinvestment Act funds to purchase 251 Secure 1000SP advanced imaging technology units from Rapiscan Systems. By June 2013, TSA had removed the units from service because the company could not develop enhanced software to enable the units to comply with the privacy requirements of the FAA Modernization and Reform Act of 2012. Rapiscan Systems assumed all costs associated with their removal and storage. In May 2013, Representative Bennie Thompson requested that we review TSA’s management of its advanced imaging technology inventory. Specifically, Mr. Thompson requested that we review the removal and potential redistribution of the noncompliant units, and related costs.
