Pursuant to a congressional request, GAO reviewed the Federal Aviation Administration's (FAA) Mode Select (Mode S) air traffic control surveillance and communication program.
Recommendations for Executive Action
|Department of Transportation||1. The Secretary of Transportation should independently evaluate the economic, operational, and technical risks involved in continuing the Mode S contract. Based on the results of this evaluation, the Secretary should direct the Administrator, FAA, to take appropriate and timely action to ensure that additional government funds are not wasted.|
|Department of Transportation||2. The Secretary of Transportation should direct the Administrator, FAA, to cancel plans to replace remaining beacon radars with Mode S and to perform a thorough analysis of requirements, alternatives, benefits, and costs. If the analysis supports replacing remaining beacon systems with Mode S, no decision to acquire additional Mode S systems should be made until the system is demonstrated to work and provide anticipated benefits.|
|Department of Transportation||3. The Secretary of Transportation should report the FAA contract administration and major system procurement processes as containing material internal control weaknesses under the Federal Managers' Financial Integrity Act (FMFIA).|
