Transportation Security Administration: Oversight of Explosive Detection Systems Maintenance Contracts Can Be Strengthened

A letter report issued by the Government Accountability Office with an abstract that begins "Mandated to screen all checked baggage by using explosive detection systems at airports by December 31, 2003, the Transportation Security Administration (TSA) has deployed two types of screening equipment: explosive detection systems (EDS), which use computer-aided tomography X-rays to recognize explosives, and explosive trace detection (ETD) systems, which use chemical analysis to detect explosive residues. This report discusses (1) EDS and ETD maintenance costs, (2) factors that played a role in these costs, and (3) the extent to which TSA conducts oversight of maintenance contracts. GAO reviewed TSA's contract files and processes for reviewing contractor cost and performance data.
