GAO-17-241R: Published: Nov 17, 2016. Publicly Released: Nov 17, 2016.
The Federal Aviation Administration (FAA) is leading the implementation of the Next Generation Air Transportation System (NextGen), a long-term initiative to transform the current radar-based air transportation system into one that uses satellite navigation, automated aircraft position reporting, and digital communications. From fiscal year 2004 through fiscal year 2016, FAA has received approxima...
Aviation Safety: FAA's Risk-Based Oversight for Repair Stations Could Benefit from Additional Airline Data and Performance Metrics [Reissued on September 2, 2016]
GAO-16-679: Published: Jul 28, 2016. Publicly Released: Jul 28, 2016.
The extent to which U.S. airlines contract out aircraft maintenance to domestic and foreign repair stations (as opposed to performing maintenance in-house) has remained relatively steady from 2010 through 2014. GAO's analysis of Bureau of Transportation Statistics (BTS) data for that period (the most recent available) showed that 28 selected U.S. airlines' annual contracted maintenance spending ra...
Airport and Airway Trust Fund: Less Than Half of Noncommercial Jet Fuel Tax Receipts Are Transferred
GAO-16-746R: Published: Aug 8, 2016. Publicly Released: Aug 8, 2016.
The total number of potentially registerable vendors of jet fuel used in noncommercial aviation is unclear, but is likely greater than the number that have registered with the Internal Revenue Service (IRS) based on industry information. While registered vendors—called “ultimate vendors”—are eligible to receive credits or refunds for sales of such jet fuel, some ultimate vendors are not cl...
Federal Aviation Administration: Preliminary Observations of Potential Air Traffic Control Restructuring Transition Issues
GAO-16-386R: Published: Feb 10, 2016. Publicly Released: Feb 10, 2016.
Based on our literature review and preliminary discussions with experts, several transition issues would need to be addressed if the U.S. air traffic control (ATC) system were to be restructured, including transition issues related to determining the funding and finance structure of the new entity, transferring assets, separating the safety regulator from the ATC entity, mitigating potential impac...
Air Travel and Communicable Diseases: Comprehensive Federal Plan Needed for U.S. Aviation System's Preparedness
GAO-16-127: Published: Dec 16, 2015. Publicly Released: Dec 16, 2015.
All of the 14 airports and 3 airlines GAO reviewed have plans for responding to communicable disease threats from abroad, although the United States lacks a comprehensive national aviation-preparedness plan aimed at preventing and containing the spread of diseases through air travel. U.S. airports and airlines are not required to have individual preparedness plans, and no federal agency tracks whi...
Next Generation Air Transportation System: Improved Risk Analysis Could Strengthen FAA's Global Interoperability Efforts
GAO-15-608: Published: Jul 29, 2015. Publicly Released: Aug 28, 2015.
Aviation industry stakeholders GAO interviewed described various factors that may affect the interoperability of the Next Generation Air Transportation System (NextGen)—a complex, long-term initiative to modernize the U.S. air-traffic management (ATM) system—with other countries' ATM modernization efforts. Interoperability allows different ATM systems and procedures to accept and use each othe...

Aviation Safety: Status of Recommendations to Improve FAA's Certification and Approval Processes
GAO-14-142T: Published: Oct 30, 2013. Publicly Released: Oct 30, 2013.
In 2010, GAO reported that industry stakeholders and experts believed that the Federal Aviation Administration's (FAA) certification and approval processes contribute positively to the safety of the national airspace system. However, stakeholders and experts also noted that negative certification and approval experiences--such as duplication of approvals--although infrequent, can result in delays...

The Federal Aviation Administration (FAA) has made some progress in addressing key challenges as it begins the gradual transition to the Next Generation Air Transportation System (NextGen). It has filled key leadership positions and developed tools to manage interdependent NextGen programs. FAA is working to address other identified challenges, including incentivizing aircraft operators to equip w...
Intermodal Transportation: A Variety of Factors Influence Airport-Intercity Passenger Rail Connectivity
GAO-13-691: Published: Aug 2, 2013. Publicly Released: Aug 2, 2013.
Most major U.S. airports have some degree of physical proximity to intercity passenger rail stations, though only 2 airports are currently collocated with intercity rail stations. Specifically, 42 of the nation's 60 large and medium hub airports are located within 10 miles of Amtrak stations; 21 of the 42 airports are within 5 miles of Amtrak stations. At the 2 collocated airports, passengers can...
