With the passage of the Aviation and Transportation Security Act (ATSA) in November 2001, TSA assumed from the Federal Aviation Administration (FAA) the majority of the responsibility for civil aviation security, including the commercial aviation system. ATSA required that TSA screen 100 percent of checked baggage using explosive detection systems by December 31, 2002. As it became apparent that certain airports would not meet the December 2002 deadline, the Homeland Security Act of 2002 in effect extended the deadline to December 31, 2003, for noncompliant airports. Under ATSA, TSA is responsible for the procurement, installation, and maintenance of explosive detection systems used to screen checked baggage for explosives. Airport operators and air carriers continued to be responsible for processing and transporting passengers' checked baggage from the check-in counter to the airplane. Explosive detection systems include EDS and ETD machines (fig. 1). EDS uses computer-aided tomography X-rays adapted from the medical field to automatically recognize the characteristic signatures of threat explosives. By taking the equivalent of hundreds of X-ray pictures of a bag from different angles, EDS examines the objects inside of the baggage to identify characteristic signatures of threat explosives. TSA has certified, procured, and deployed EDS manufactured by three companies--L-3 Communications Security and Detection Systems (L-3); General Electric InVision, Inc. (GE InVision); and Reveal Imaging Technologies, Inc. (Reveal). In general, EDS is used for checked baggage screening. ETD machines work by detecting vapors and residues of explosives. Human operators collect samples by rubbing bags with swabs, which are then chemically analyzed in the ETD machine to identify any traces of explosive materials. ETD machines are used for both checked baggage and passenger carry-on baggage screening. TSA has certified, procured, and deployed ETD machines from three manufacturers, Thermo Electron Corporation, Smiths Detection, and General Electric Company. TSA's EDS and ETD maintenance contracts provide for preventative and corrective maintenance. Preventative maintenance includes scheduled activities, such as changing filters or cleaning brushes, to increase machine reliability and are performed monthly, quarterly, or yearly based on the contractors' maintenance schedules. Corrective maintenance includes actions performed to restore machines to operating condition after failure, such as repairing the conveyer belt mechanism after a bag jams the machine. TSA is responsible for EDS and ETD maintenance costs after warranties on the machines expire. From June 2002 through March 2005, Boeing was the prime contractor primarily for the installation and maintenance of EDS and ETD machines at over 400 U.S. airports. TSA officials stated that the Boeing contract was awarded at a time when TSA was a new agency with many demands and extremely tight schedules for meeting numerous congressional mandates related to passenger and checked baggage screening. The cost reimbursement contract entered into with Boeing had been competitively bid and contained renewable options through 2007. Boeing subcontracted for EDS maintenance through firm-fixed-price contracts with the original EDS manufacturers, GE InVision and L-3, which performed the maintenance on their respective EDS. Boeing subcontracted for ETD maintenance through a firm-fixed-price contract with Siemens. Consistent with language in the fiscal year 2005 House Appropriations Committee report and due to TSA's acknowledgment of Boeing's failure to control costs, TSA received DHS authorization to negotiate new EDS and ETD maintenance contracts in January 2005. In March 2005, TSA signed firm-fixed-price contracts for EDS and ETD maintenance. TSA awarded a competitively bid contract to Siemens to provide maintenance for ETD machines. According to TSA, it negotiated sole source contracts with L-3 and GE InVision for maintaining their respective EDS because they are the original equipment manufacturers and owners of the intellectual property rights of their respective EDS. In September 2005, TSA awarded a competitively bid firm-fixed-price contract to Reveal for both the procurement and maintenance of a reduced size EDS. TSA obligated almost $470 million from fiscal year 2002 through fiscal year 2005 for EDS and ETD maintenance, according to TSA budget documents. In fiscal year 2006, TSA estimates it will spend $199 million and has projected it will spend $234 million in fiscal year 2007. According to TSA officials, in fiscal year 2004, TSA requested and received approval to reprogram about $32 million from another account to EDS/ETD maintenance due to higher levels of maintenance costs than expected. Similarly, in fiscal year 2005, TSA requested and received approval to reprogram $25 million to fund the L-3 contract and to close out the Boeing contract. TSA was not able to provide us with data on the maintenance cost per machine before fiscal year 2005 because, according to TSA officials, TSA's previous contract with Boeing to maintain EDS and ETD machines was not structured to capture these data. Table 1 identifies the maintenance costs by type of EDS and ETD machine for fiscal years 2005 and 2006. TSA did not provide us with projections of EDS and ETD maintenance costs beyond 2007. TSA officials told us that future costs will be influenced by the number, type, quantity, and locations of machines necessary to support system configurations at airports, such as the extent to which EDS are integrated with airport baggage conveyor systems or are operated in stand-alone modes. Further, TSA officials told us that future EDS and ETD maintenance costs are dependent on decisions related to the deployment of new technologies and the refurbishment of existing equipment, among other things. The current contracts would have negotiated maintenance prices per machine through March 2009, if TSA decides to exercise option years in the contracts. We identified different factors that have played a role in costs to date and that will influence future maintenance costs for EDS and ETD machines. According to a September 2004 DHS OIG report, TSA did not follow sound contracting practices in administering the Boeing contract, which was primarily for the installation and maintenance of EDS and ETD machines. According to DHS OIG officials, TSA's failure to control costs under the Boeing contract, including the lack of sound contracting practices, contributed to increases in maintenance costs. Among other things, the DHS OIG report stated that TSA had paid provisional award fees totaling $44 million through December 2003 without any evaluation of Boeing's performance. In response to the DHS OIG, TSA agreed to recover any excessive award fees paid to Boeing, if TSA determined that such fees were not warranted. In commenting on our draft report in July 2006, DHS stated that TSA has conducted a contract reconciliation process to ensure that no fees would be paid on costs that exceeded the target due to poor contractor performance. Further, DHS stated that TSA and Boeing had reached an agreement in principle on this matter and that the documentation was in the approval process with closure anticipated in July 2006. In its report accompanying the DHS Appropriations Bill for fiscal year 2007, the House Appropriations Committee stated its need for a report from TSA on any actions it has taken to collect excessive award fees, how much of the fees have been received to date, and specific plans to obligate these collections and cited TSA's plans to use any cost recoveries to purchase and install additional EDS. These actions were based on the committee's long-standing concerns about the increasing costs for EDS and ETD maintenance. In addition to matters related to the Boeing contract, TSA officials stated that another factor contributing to cost increases were the larger than expected number of machines that came out of warranty and their related maintenance costs. According to TSA officials, they were not able to determine the cost impact of these additional machines because the Boeing contract was not structured to provide maintenance costs for individual machines. With regard to future EDS and ETD maintenance costs under firm-fixed- price contracts, maintenance costs per machine will increase primarily by an annual escalation factor in the contracts that takes into account the employment cost index and the consumer price index, if TSA decides to exercise contract options. In addition, future maintenance costs may be affected by a range of factors, including the number of machines deployed and out of warranty, conditions under which machines operate, contractor performance requirements, the emergence of new technologies or improved equipment, and alternative screening strategies. Lastly, life-cycle cost estimates were not developed for the Boeing, Siemens, L-3, and GE InVision contracts before the maintenance contracts were executed, and, as a result, TSA did not have a sound estimate of maintenance costs for all the years the machines are expected to be in operation. In August 2005, TSA hired a contractor to define parameters for a life-cycle cost model, among other things. This contract states that TSA and the contractor will work together to ensure that the full scope of work is planned, coordinated, and executed according to approved schedules. In commenting on our draft report in July 2006, DHS stated that the TSA contractor estimated completing a prototype life-cycle cost model by September 2006. Further, DHS stated that TSA's evaluation of the prototype would begin immediately upon delivery and that full implementation of an EDS life-cycle cost model would be completed within 12 months after the prototype had been approved. According to a TSA official, the life-cycle cost model would be useful in determining machine reliability and maintainability and to inform future contract negotiations, such as when to replace a machine versus continuing to repair it. We identified several actions TSA has taken to control EDS and ETD maintenance costs. First, TSA entered into firm-fixed-price contracts starting in March 2005 with maintenance contractors, which offer TSA certain advantages over cost reimbursement contracts because price certainty is guaranteed for up to 5 years if TSA exercises options to 2009. Also, TSA included several performance requirements in the Siemens, L-3, GE InVision, and Reveal contracts, including the collection of metrics related to machine reliability, maintainability, and availability and required specific cost data related to maintenance and repair. TSA officials told us that these data will assist them in monitoring the contractor performance as well as informing future contract negotiations for equipment and maintenance. These contracts also stipulate that maintenance contractors meet monthly with TSA to review all pertinent technical schedules and cost aspects of contracts. TSA also incorporated provisions in the L-3 and GE InVision contracts to specify that the agreed price for maintaining EDS would be paid only if the contractor performs within specified mean downtime (MDT) requirements. Contractors submit monthly invoices for 95 percent of the negotiated contract price for the month and then submit a MDT report to justify the additional 5 percent. Consequently, if the contractor fails to fulfill the MDT requirements, it is penalized 5 percent of the negotiated monthly maintenance price. As of February 2006, neither GE InVision nor L-3 had been penalized for missing their MDT requirements. The allowable MDT is lowered from 2005 to subsequent renewable years in the contract, as shown in table 2. With regard to TSA's oversight of EDS and ETD contractor performance, TSA's acquisition policies and GAO standards for internal controls call for documenting transactions and other significant events, such as monitoring contractor activities. The failure of TSA to develop internal controls and performance measures has been recognized by other GAO and DHS OIG reviews. TSA has policies and procedures for monitoring its contracts and has included contractor performance requirements in the current EDS and ETD maintenance contracts. However, TSA officials provided no evidence that they are reviewing maintenance cost data provided by the contractor because they are not required to document such activities. For example, even though TSA officials told us that they are reviewing required contractor data, including actual maintenance costs related to labor hours and costs associated with replacing and shipping machine parts, they did not have any documentation to support this. TSA officials told us that they have begun to capture these data to assist them in any future contract negotiations. Further, TSA officials provided no evidence that performance data for corrective and preventative maintenance required under contracts are being reviewed. TSA officials told us that they perform such reviews, but do not document their activities since there are no TSA policies or procedures requiring them to do so. Therefore, TSA could not provide assurance that contractors are complying with contract performance requirements. For example, although TSA documents monthly meetings with contractors to discuss performance data, TSA officials did not provide evidence that they independently determine the reliability and validity of data required by the contracts, such as mean time between failures and mean time to repair, which are important to making informed decisions about future purchases of EDS and ETD equipment and their associated maintenance costs. Further, TSA officials provided no evidence that they ensure that contractors are performing scheduled preventative maintenance. TSA officials told us that they review the contractor- submitted data to determine whether contractors are fulfilling their contractual obligations, but do not document their activities because there are no TSA policies or procedures to require such documentation. Additionally, for EDS contracts with possible financial penalties, TSA officials told us that they review contractor-submitted mean downtime data on a monthly basis to determine the reliability and validity of the data and to determine whether contractors are meeting contract provisions or should be penalized. However, TSA officials do not document these activities because there are no TSA policies or procedures requiring them to do so. As a result, without adequate documentation, there is no assurance as to whether or not contractors are meeting contract provisions or that TSA has ensured that it is making appropriate payments for services provided. The cost of maintaining checked baggage-screening equipment has increased as more EDS and ETD machines have been deployed and warranties expire. TSA's move in March 2005 to firm-fixed-price maintenance contracts for EDS and ETD maintenance was advantageous to the government in that it helps control present and future maintenance costs. Firm-fixed-price contracts also help ensure price certainty and therefore are more predictable. However, unresolved issues remain with the past contractor, specifically fees awarded to former contractor Boeing that may have been excessive due to a lack of timely evaluation of the contractor's performance. The House Appropriations Committee has expressed concern about these unresolved issues; specifically, what actions TSA has taken to recover these excessive fees, and the extent to which any collections might impact future TSA obligations. Closing out the Boeing contract is essential to resolving these issues. In responding to our draft report, DHS stated that the completion of an EDS life-cycle cost is over a year away. Absent such a life-cycle cost model, TSA may not be identifying cost efficiencies and making informed procurement decisions regarding the future purchase of EDS and ETD machines and maintenance contracts. Further, TSA must provide evidence of its reviews and analyses of contractor-submitted data and perform analyses of contractor data to determine the reliability and validity of the data and to provide assurance of compliance with contract performance requirements and internal control standards. Without stronger oversight, TSA will not have reasonable assurance that contractors are performing as required and that full payment is justified based on meeting mean downtime requirements. To help improve TSA's management of EDS and ETD maintenance costs and strengthen oversight of contract performance, we recommend that the Secretary of Homeland Security instruct the Assistant Secretary, Transportation Security Administration, to take the following three actions: establish a timeline to complete its evaluation and close out the Boeing contract and report to congressional appropriations committees on its actions, including any necessary analysis, to address the Department of Homeland Security Office of Inspector General's recommendation to recover any excessive fees awarded to Boeing Service Company; establish a timeline for completing life-cycle cost models for EDS, which TSA recently began; and revise policies and procedures to require documentation of the monitoring of EDS and ETD maintenance contracts to provide reasonable assurance that contractor maintenance cost data and performance data are recorded and reported in accordance with TSA contractual requirements and self-reported contractor mean downtime data are valid, reliable, and justify the full payment of the contract amount. We provided a draft of this report to DHS for its review and comment. On July 24, 2006, we received written comments on the draft report. DHS, in its written comments, concurred with our findings and recommendations, and agreed that efforts to implement these recommendations are essential to a successful explosive detection systems program. DHS stated that it has initiated efforts to improve TSA's management of EDS and ETD maintenance costs and strengthen oversight of contract performance. Regarding our recommendation that TSA establish a timeline to close out the Boeing contact and report to congressional committees on its actions to recover any excessive fees, DHS stated that TSA has conducted a contract reconciliation process to ensure that no fees would be paid on costs that exceeded the target due to poor contractor performance and that Boeing and TSA have reached an agreement in principle on this matter and the documentation is in the approval process with closure anticipated in July 2006. Regarding our recommendation to establish a timeline for completing the EDS life-cycle cost model, DHS stated that TSA expects to complete its prototype evaluation in September 2006 and that the EDS life-cycle cost model will be completed 12 months after the prototype has been approved. Regarding our recommendation to revise TSA policies and procedures to require documentation of its monitoring of EDS and ETD maintenance contracts, DHS stated that a TSA contractor is developing automated tools to perform multiple analyses of contractor- submitted data that DHS said would allow TSA to accurately and efficiently certify the contractors' performance against their contractual requirements and would allow TSA to independently validate and verify maintenance and cost data. The department's comments are reprinted in appendix II. We will send copies of this report to the Secretary of Homeland Security and the Assistant Secretary, Transportation Security Administration, and interested congressional committees. We will also make copies available to others upon request. In addition, the report will be available at no charge on GAO's Web site at http://www.gao.gov.

Rep. No. 109-241, at 52 (2005). TSA interprets the term explosive detection system to include both explosive detection systems (EDS) and explosive trace detection (ETD) machines. maintenance of explosive detection systems (EDS) and explosive trace detection (ETD) machines? What factors played a role in EDS and ETD maintenance costs and what factors could affect future costs? What has TSA done to control EDS and ETD maintenance costs? To what extent does TSA oversee the performance of EDS and ETD maintenance contractors? To determine TSA costs to maintain EDS and ETD machines we reviewed TSA contract files and budget documents for fiscal years 2003 through 2007, and interviewed TSA headquarters officials, Department of Homeland Security Office of the Inspector General (DHS OIG) officials, and EDS and ETD contractor representatives. For purposes of our review, we focused on the amounts obligated under contracts to maintain the machines. We did not review TSA's negotiations for maintenance services or the process for awarding contracts, nor did we assess other direct or indirect costs related to TSA or DHS employees engaged in contract administration or other related items. To determine what factors played a role in maintenance costs and what TSA has done to control costs, we: reviewed TSA contract files, acquisition and strategic plans, budget documents, TSA processes for reviewing contract cost and performance data, and a DHS OIG report;and interviewed TSA headquarters officials, DHS OIG officials, and EDS and ETD contractor representatives. To determine the extent of TSA contract oversight, we: reviewed TSA contract files and processes for reviewing contract performance data, interviewed TSA headquarters officials and EDS and ETD contractor representatives, and reviewed GAO standards for internal controls We performed our work from January 2006 through June 2006 in accordance with generally accepted government auditing standards. GAO, Standards for Internal Control in the Federal Government, GAO/AIMD-00-21.3.1 (Washington, D.C.: November 1999). According to TSA budget documents, TSA has obligated almost $470 million from fiscal year 2002 through fiscal year 2005 for EDS and ETD maintenance. In fiscal year 2006, TSA estimates it will spend $199 million and has projected it will spend $234 million in fiscal year 2007. TSA was unable to provide us data on maintenance cost per machine prior to fiscal year 2005 because, according to TSA officials, its previous contract with Boeing Service Company (Boeing) to maintain EDS and ETD machines was not structured to capture these data. TSA did not provide us with projections of EDS and ETD maintenance costs beyond fiscal year 2007, although TSA has negotiated maintenance prices per machine through fiscal year 2009. TSA was mandated to screen all checked baggage using explosive detection systems at airports by December 31, 2003.1 Explosive Detection Systems (EDS) use computer-aided tomography X-rays to recognize the characteristics of explosives. In general, EDS are used for checked baggage screening. Explosive Trace Detection (ETD) machines use chemical analysis to detect traces of explosive material vapors or residues. ETD machines are used for both passenger carry-on baggage and checked baggage screening. According to TSA budget documents, TSA will have deployed over 1,400 EDS and 6,600 ETD machines at baggage screening locations in over 400 airports nationwide by the end of fiscal year 2006. The Aviation and Transportation Security Act, Pub. L. No. 107-71 SS 110(b), 115 Stat. 597, 615 (2001) mandated, among other things, that all checked baggage at U.S. airports be screened using explosive detection systems by December 31, 2002. Section 425 of the subsequently enacted Homeland Security Act of 2002, Pub. L. No. 107-296, 116 Stat. 2135, 2185-86, in effect, extended this mandate to December 31, 2003. See 49 U.S.C. SS 44901(d). TSA is responsible for the EDS and ETD maintenance costs EDS and ETD maintenance includes preventative maintenance--scheduled activities to increase machine reliability that are performed monthly, quarterly, and yearly based on the contractors' maintenance schedules and corrective maintenance--actions performed to restore machines to operating condition after failure. A TSA official told us that typical EDS warranties are for one year and that ETD warranties are for 2 years. From June 2002 through March 2005, Boeing was the prime contractor for the installation and maintenance of EDS and ETD machines at over 400 U.S. airports. TSA officials stated that the Boeing contract was awarded at a time when TSA was a new agency with many demands and extremely tight schedules for meeting numerous congressional mandates related to passenger and checked baggage screening. Boeing had a cost reimbursement contractwith TSA, which was competitively bid and contained renewable options to 2007. Firm fixed price contracts provide for a price that is not subject to any adjustment on the basis of the contractor's cost experience in performing the contract. This contract type places upon the contractor maximum risk and full responsibility for all costs and resulting profit and loss. It provides maximum incentive for the contractor to control costs and perform effectively and imposes a minimum administrative burden upon the contracting parties. In March 2005, TSA signed firm fixed price contracts for EDS and ETD maintenance. TSA awarded a competitively bid contract to Siemens to provide maintenance for ETD machines. TSA negotiated sole source contracts with L-3 and GE InVision because they are the original equipment manufacturers and owners of the intellectual property of their respective EDS. TSA can exercise 4 1-year options on all three contracts through March 2009. In September 2005, TSA awarded a competitively bid firm fixed price contract to Reveal Imaging Technologies, Inc., (Reveal) for both the procurement and maintenance of a reduced-size EDS. According to TSA budget documents, TSA has obligated almost $470 million for EDS and ETD maintenance from fiscal years 2002 through 2005. EDS and ETD Machine Maintenance Budget Amounts, Fiscal Years 2002 through 2007 (In millions) maintenance grew from $14 million in fiscal year 2002 to an estimated $199 million in fiscal year 2006. In fiscal year 2007, TSA projects it will spend $234 million. Appropriated (as revised) 75 100 205 200 234 the maintenance cost per machine prior to fiscal year 2005 because, according to TSA officials, its previous contract with Boeing to maintain EDS and ETD machines was not structured to capture these data. According to TSA officials, in fiscal year 2004, TSA requested and received approval to reprogram about $32 million due to higher levels of maintenance costs than expected. In fiscal year 2005, TSA requested and received approval to reprogram $25 million to fund the L-3 contract ($16.6 million) and to closeout the Boeing contract ($8.4 million), which has yet to be closed. TSA officials did not provide us with projections of costs beyond 2007. However, current contracts have negotiated maintenance prices per machine through March 2009, if TSA decides to exercise option years in the contracts. Future EDS and ETD maintenance costs depend on decisions made as outlined in a February 2006 TSA strategic planning framework for screening checked baggage using EDS and ETD. Among other things, the plan discusses options for the deployment of new technologies and refurbishment of existing equipment. Different factors have played a role in costs to date and will influence future maintenance costs for EDS According to a September 2004 DHS OIG report, TSA did not follow sound contracting practices in administering the Boeing contract, which was primarily for the installation and maintenance of EDS and ETD machines. Among other things, the DHS OIG found that TSA had paid provisional award fees totaling $44 million through December 2003 without any evaluation of Boeing's performance. GAO has identified similar instances of agencies' failure to properly use incentives in making award fees. See GAO, Defense Acquisitions: DOD Has Paid Billions in Award and Incentive Fees Regardless of Acquisition Outcomes, GAO-06-66 (Washington, D.C.: December 2005). For EDS contracts, future labor and material costs could not be determined, so TSA negotiated an escalation factor to be used to determine pricing for the contract option years. For the ETD contracts, TSA determined after a review of cost data, that it would apply a 4 percent escalation factor to prices in the contract option years. The employment cost index is a measure of the change in the cost of labor, free from the influence of employment shifts among occupations and industries. The consumer price index is a measure of the average change in prices over time of goods and services purchased by households. machines deployed and out of warranty, conditions under which machines operate, mean downtime requirements, the emergence of new technologies or improved equipment, and alternative screening strategies. TSA's February 2006 strategic plan framework for screening checked baggage over the next 20 years discusses factors that may impact future maintenance costs. For example, the framework discusses the refurbishment of existing machines and the deployment of new technologies, but does not outline the number of machines or specific time frames for implementation. Additionally, the impact of these strategies on future maintenance costs is unknown.1 If no new equipment or maintenance providers emerge, TSA may pay a premium in future sole source contracts where intellectual property rights are involved. For example, because L-3 and GE InVision had intellectual property rights on their machines, their maintenance contracts were not bid competitively and therefore prices were not subject to the benefits of market forces. TSA issued its strategic plan framework for screening checked baggage using EDS and ETD machines in response to various congressional mandates, congressional committee directives, and GAO recommendations. Siemens, L-3, and GE contracts before the maintenance contracts were executed and, as a result, TSA did not have a complete picture of all maintenance costs. In August 2005, TSA hired a contractor to define parameters for a lifecycle cost model. A TSA official told us that the contractor began work on a lifecycle cost model for EDS in February 2006 and did not know when the model would be completed. for up to five years if TSA exercises options to 2009. TSA did not provide per-unit maintenance costs prior to March 2005 because the Boeing contract was not structured to capture these data.

TSA included several contractor performance requirements in the Siemens, L-3, GE InVision, and Reveal contracts. Metrics related to Reliability, Maintainability, and Availability (RMA) of the machines must be reported to TSA.1 Specific cost data related to maintenance and repair must be reported to TSA. Contractors are required to meet monthly with TSA to review all pertinent technical, schedule, and cost aspects of the contract, including an estimate of the work to be accomplished in the next month; performance measurement information; and any current and anticipated problems. Includes metric s such as m ean tim e between failur es (gener ally the total time a m achi ne is av ailable to perform its required missi on divided by the num ber of failur es over a given per iod of time) and oper ational availability (generally the percentage of time, duri ng operational hours, that a machine is available to perform its requir ed mission).

Contractors submit monthly invoices for 95 percent of the negotiated contract price for the month and then submit an MDT report to justify the additional 5 percent. Consequently, if the contractor fails to fulfill the MDT requirements, it is penalized 5 percent of the negotiated monthly maintenance price. As of February 2006, neither GE InVision nor L-3 have been penalized for missing their MDT. The allowable MDT is lowered from 2005 to subsequent renewable years in the contract, as shown in the table below.

Summary:
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. TSA obligated almost $470 million from fiscal years 2002 through 2005 for EDS and ETD maintenance, according to TSA budget documents. In fiscal year 2006, TSA estimates it will spend $199 million and has projected it will spend $234 million in fiscal year 2007. TSA was not able to provide GAO with data on the maintenance cost per machine before fiscal year 2005 because, according to TSA officials, its previous contract with Boeing to install and maintain EDS and ETD machines was not structured to capture these data. Several factors have played a role in EDS and ETD maintenance costs. According to a September 2004 Department of Homeland Security's Office of Inspector General report, TSA did not follow sound contracting practices in administering the contract with Boeing, and TSA paid provisional award fees totaling $44 million through December 2003 without any evaluation of Boeing's performance. TSA agreed to recover any excessive award fees paid to Boeing if TSA determined that such fees were not warranted. In responding to our draft report, DHS told us that TSA and Boeing had reached an agreement in principle on this matter and that documentation was in the approval process with closure anticipated in July 2006. Moreover, TSA did not develop life-cycle cost models before any of the maintenance contracts were executed and, as a result, TSA does not have a sound estimate of maintenance costs for all the years the machines are expected to be in operation. DHS also stated in its comments on our draft report that a TSA contractor expected to complete a prototype life-cycle cost model by September 2006 and that TSA anticipated that the EDS model would be completed 12 months after the prototype was approved. Without such an analysis, TSA may not be identifying cost efficiencies and making informed procurement decisions on future purchases of EDS and ETD machines and maintenance contracts. TSA has taken actions to control costs, such as entering into firm-fixed-price contracts for maintenance starting in March 2005, which have advantages to the government because price certainty is guaranteed. Further, TSA incorporated standard performance requirements in the contracts including metrics related to machine reliability and monthly performance reviews. For EDS contractors, TSA has specified that the full agreed price would be paid only if mean downtime (i.e., the number of hours a machine is out of service in a month divided by the number of times that machine is out of service per month) requirements are met. Although TSA has policies for monitoring contracts, TSA officials provided no evidence that they are reviewing required contractor-submitted performance data, such as mean downtime data. TSA officials told GAO that they perform such reviews, but do not document their activities because there are no TSA policies and procedures requiring them to do so. As a result, without adequate documentation, TSA does not have reasonable assurance that contractors are performing as required and that full payment is justified based on meeting mean downtime requirements.
