Lapse in Appropriations

Please note that a lapse in appropriations has caused GAO to shut down its operations. Therefore, GAO will not be able to publish reports or otherwise update this website until GAO resumes operations. In addition, the vast majority of GAO personnel are not permitted to work. Consequently, calls or emails to agency personnel may not be returned until GAO resumes operations. For details on how the bid protest process will be handled during the shutdown, please see the legal decisions page. For information related to the GAO Personnel Appeals Board (PAB), please see the PAB webpage.

Description

After a shutdown of the national airspace in 2023 due to an aging air traffic control (ATC) system outage, Federal Aviation Administration (FAA) conducted an operational risk assessment to evaluate the sustainability of all ATC systems. The assessment determined that of its 138 systems, 51 (37 percent) were unsustainable and 54 (39 percent) were potentially unsustainable.

These challenges are due to, among other things, availability of parts, growing airspace demand, and expanding mission needs. FAA anticipates continued growth and forecasts that air travel will increase, on average, by 6.2 percent annually.

GAO is making seven recommendations to FAA to help address these issues.
