Both the House Transportation and Infrastructure Committee and the Senate Committee on Commerce, Science, and Transportation acted favorably on bills to reauthorize the Federal Aviation Administration (FAA) and other aviation programs during the last week of June. The two bills, H.R. 2997 and S. 1405, have significant differences, many of them related to provisions in the House bill that would create a not-for-profit private corporation to take over responsibility for running the national air traffic control system. The Senate bill contains no similar provisions, and the path forward for the legislation will depend on whether the two houses can reach agreement on an issue that they were unable to bridge last year. Lack of agreement on air traffic control reforms in the 114^th Congress led to the passage of a one-year aviation extension (P.L. 114-190) that will expire at the end of FY2018.

Whereas S. 1405 would fund FAA programs through FY2021, H.R. 2997 would extend funding through FY2023 (see Table 1). Since the House committee bill provides that the proposed corporation would take over air traffic services starting in FY2021, it would eliminate all Airport and Airway Trust Fund (AATF) financing for FAA operations and funding authorization for FAA air traffic facilities and equipment beyond FY2020. AATF funding of facilities and equipment not directly tied to air traffic functions and general fund financing of aviation safety programs, however, would continue through FY2023 under the House bill.

Reforming Air Traffic Control

Under H.R. 2997, FAA facilities and equipment would be transferred without charge to the proposed corporation, which would be run by a board comprising industry stakeholders. The FAA would become principally a safety regulator, rather than managing air traffic control with its own employees.

The bill would authorize the proposed corporation to charge user fees to cover its costs. This has been a particular point of contention; although the bill would exempt noncommercial aircraft from user fees, general aviation and business aviation groups have opposed the user-fee model, fearing that fees could be charged more broadly in the future and that airlines would have too much influence over how the aviation system is run.

Proponents argue that the user fee model would charge airlines for the services they use, would resolve the loss of revenue from the current 7.5% ticket tax stemming from airlines' increased use of untaxed ancillary fees, and would provide the corporation with a reliable long-term funding source to support investments in new air traffic control technology. However, presumed modifications to existing taxes that provide revenue to the AATF fall within the jurisdiction of the House Committee on Ways and Means, which has yet to weigh in on the proposal. Some Members of Congress have objected that aviation user fees, like the taxes they would supplant, should be subject to some level of congressional oversight rather than being left solely to the corporation's board.

Other Key Issues

The bills differ in how they address a number of other key issues:

• While both the House and Senate committee bills pave the way for delivery services using small drones and facilitate small commercial drone operations in low-altitude airspace, both bills would continue to limit FAA's authority to regulate model aircraft and drones operated strictly for hobby or recreation. The Senate bill, however, would allow FAA to require model aircraft to register, a practice that was halted by a recent court decision.
• The Senate committee's bill would modify training standards for airline pilots, allowing FAA to consider alternatives to the existing 1,500-flight-hour requirement. Proponents argue that the increased flexibility could help regional airlines address pilot hiring needs, while opponents argue that doing so could erode safety improvements made following the February 2009 crash of a commuter flight near Buffalo, NY.
• The House committee bill would significantly increase discretionary funding for Essential Air Service (EAS), the program that subsidizes airline service to small communities, starting in FY2021, because FAA would no longer collect the overflight fees that currently provide baseline mandatory funding for EAS if the proposed air traffic privatization plan is implemented. The Senate committee bill authorizes appropriation for EAS at an annual level of $175 million for FY2018-2021, unchanged from the amount appropriated in FY2017.
• Both bills would ease restrictions on the ability of airports to impose passenger facility charges to fund airport improvements. However, the current limit of $4.50 per flight segment would remain.
• Both bills address complaints about crowding aboard airplanes. H.R. 2997 would require FAA to issue regulations establishing minimum dimensions for passenger seats, including seat pitch (the distance between rows), within one year of enactment. S. 1405 would require FAA to initiate a study of minimum seat pitch within 18 months of enactment, and also would require FAA to review whether changes in seat size and pitch affect the ability to evacuate an aircraft in an emergency.
