Recommendations Database

GAO’s recommendations database contains report recommendations that still need to be addressed. GAO’s priority recommendations are those that we believe warrant priority attention. We sent letters to the heads of key departments and agencies, urging them to continue focusing on these issues. Below you can search only priority recommendations, or search all recommendations.

Our recommendations help congressional and agency leaders prepare for appropriations and oversight activities, as well as help improve government operations. Moreover, when implemented, some of our priority recommendations can save large amounts of money, help Congress make decisions on major issues, and substantially improve or transform major government programs or agencies, among other benefits.

As of October 25, 2020, there are 4812 open recommendations, of which 473 are priority recommendations. Recommendations remain open until they are designated as Closed-implemented or Closed-not implemented.

Recommendation: The Secretaries of Defense and of Transportation should address ADS-B Out security concerns by approving one or more solutions that address ADS-B Out -related security risks or incorporating mitigations for security risks into the existing draft memorandum of agreement. These approved solutions should address operations, physical, cyber-attack, and electronic warfare security risks; and risks associated with divesting secondary-surveillance radars. The solution or mitigations should be approved as soon as possible in order to allow sufficient time for implementation.

Agency: Department of Defense
Status: Open

Comments: DOD partially concurred with this recommendation. As of August 2018, DOD and the FAA signed a memorandum of agreement that that establishes a framework for DOD and FAA to jointly address the provision to allow certain aircraft not to broadcast and airspace monitoring and defense security issues related to ADS-B, and identifies a path to fully address the recommendations in our report. The memorandum of agreement was a first step to address the security issues we highlighted in the report; however, FAA still needs to publish a National Procedural Guidance for accommodation of DOD needs for mixed-equipment operations and operational security concerns (expected December 2018).
