A August 2025 U.S. Government Accountability Office report warns that staffing shortages among National Weather Service meteorologists embedded at FAA air traffic control centers may pose risks to the safety and efficiency of the National Airspace System. These meteorologists provide critical real-time weather briefings to air traffic controllers to help route flights safely around severe weather, but a February 2025 amendment to the FAA-NWS interagency agreement reduced the required staffing level from 90 to 81 positions. The GAO urges urgent action from the Departments of Transportation and Commerce before the interagency agreement expires in September 2025.

A September 2024 U.S. Government Accountability Office report found that the FAA's air traffic control systems are critically outdated, with 37% rated unsustainable and 39% potentially unsustainable out of 138 total systems reviewed. The agency has been slow to modernize the most at-risk systems, with some upgrades not planned for completion until 2030–2035, and four critical systems lacking any modernization plans at all. The GAO made seven recommendations to improve FAA oversight and accelerate upgrades to protect the safety and efficiency of the national airspace.

Former King County International Airport (BFI) Noise Officer Sharyn Parker's prepared notes for a GAO interview outline significant concerns about FAA regulatory failures and Sea-Tac Airport's inadequate noise mitigation practices in the Seattle region. Parker argues that the FAA has consistently failed to require Sea-Tac to update noise exposure maps, enforce timely sound mitigation programs, or conduct meaningful public outreach — particularly for minority communities disproportionately affected by flight path changes like the Greener Skies/RNP initiative. The notes also highlight contradictions between Sea-Tac's deliberately low flight-operation projections in its Part 150 noise studies and the far higher growth figures used in its capital development plans.

A community member wrote to a GAO researcher studying NextGen aviation noise impacts near Seattle-Tacoma International Airport, urging that community complaints be paired with responses from the FAA and Port of Seattle to ensure credibility. Key concerns raised include an outdated noise exposure map that has not been updated despite significant growth in air traffic, and the FAA's alleged refusal to answer questions submitted as far back as April 2018. The letter argues that without official rebuttals or supporting documentation, community perceptions risk appearing unsubstantiated and could undermine the integrity of the GAO study.

A 2013 U.S. Government Accountability Office report found that the FAA made limited progress in modernizing the air transportation system through its NextGen initiative, with ongoing challenges reducing expected benefits. The report highlights the FAA's Greener Skies project at Seattle-Tacoma International Airport, initiated by Alaska Airlines, which aimed to shorten flight paths and route aircraft over water to save fuel, but excluded certain eastern flight procedures due to community concerns about aviation noise. The report notes that the full benefits of new flight procedures depend heavily on how often airlines and pilots actually use them.

A 1998 U.S. General Accounting Office report examined whether the FAA was required to enforce a policy mandating written declarations of local support before awarding noise mitigation grants to Seattle-Tacoma International Airport. The report found that while FAA policy called for such written declarations from affected cities and counties, neither federal law nor FAA regulations legally required them. FAA officials maintained they still met the broader statutory requirement of ensuring noise mitigation projects were consistent with local plans.
