Grant Assurance Compliance

I. Introduction

The federal airport grant assurances program is a regulatory framework established by 49 U.S.C. § 47107 and FAA Order 5190.6B that governs U.S. airport operations and finance. The 39 Grant Assurances constitute statutory conditions codified in 49 U.S.C. § 47107 and FAA Order 5190.6B that airport sponsors agree to meet per 49 U.S.C. § 47107 to receive federal Airport Improvement Program (AIP) funding and to maintain eligibility for future federal support.

For airport finance professionals, legal counsel, airport executives, and governing boards, 49 U.S.C. § 47107 conditions federal funding eligibility on grant assurances compliance. Violations can result in suspension of AIP eligibility under 49 U.S.C. § 47107(b), subject to FAA enforcement procedures in 14 CFR Part 16. Documented FAA Part 16 dockets from 2020–2025 record orders and formal adjudication, with violation categories detailed in Appendix C. The Federal Aviation Administration (FAA), through its Airports Division and Regional Offices, maintains enforcement authority under 14 CFR Part 16 and has pursued violations in documented cases from 2020–2025.

This reference guide provides airport finance and operations professionals with analysis of all 39 Grant Assurances as listed in the FAA Grant Assurances Document (April 2025 update), the statutory framework underlying them, FAA enforcement mechanisms, documented compliance issues from FAA Part 16 dockets (2020–2025), examples of documented compliance programs, and FAA-recommended practices for maintaining compliance. This guide summarizes the regulatory environment as defined by federal law, FAA orders and policy, and recent enforcement decisions (see Appendix A for statutes).

Grant assurances vary in character depending on the type of federal grant received. Per FAA Grant Assurances Document (April 2025 update), land grants (including federally-owned land leased for airport purposes) create assurance obligations per FAA Grant Assurances Document (April 2025 update). Development grants impose 20-year assurance periods (standard for most AIP grants per FAA policy), with 'rolling' obligations when new grants are received. Planning grants and terminal development grants have their own specific assurance frameworks. Airports can determine which assurances apply for long-term planning and financial forecasting by consulting the FAA Grant Assurances Document (April 2025 update), which lists all 40 assurances and their applicability by grant type.

This guide covers the historical development of grant assurances from their origins in the Federal Airport Act of 1946 through the 39-assurance framework under the FAA Reauthorization Act of 2024; examination of each major assurance category; FAA compliance monitoring and enforcement procedures; formal Part 16 complaint processes; the intersection of grant assurances with airport finance, including airline use agreements, revenue bonds, and credit ratings; and documented compliance programs for maintaining compliance with all 39 Grant Assurances as defined by FAA Order 5190.6B.

Airport sponsors receiving AIP funding are subject to statutory obligations under 49 U.S.C. § 47107(b) that bind successors, as affirmed in FAA Part 16 dockets (2020–2025). This permanence, combined with the FAA's enforcement authority as defined in 14 CFR Part 16 and FAA Order 5190.6B, creates ongoing compliance obligations for airport management.

II. Historical Development of Grant Assurances

A. The Federal Airport Act of 1946

The Federal Airport Act of 1946 (60 Stat. 170) marked the beginning of federal investment in airport infrastructure through federal assistance. This statute recognized that civil aviation required facilities meeting operational standards and that communities historically lacked resources to develop airport infrastructure without federal assistance. The 1946 Act established the principle that federal funding for airports would not come without conditions—airport sponsors receiving federal funds had to agree to use those facilities in ways consistent with federal policy objectives.

The 1946 Act required that airports receiving federal funds had to remain open to the public (not be exclusive facilities), could not discriminate against users on the basis of aircraft type or size, and had to maintain the facility in operational condition. These obligations persist in current grant assurances.

B. The Airport and Airway Development Act of 1970

The Airport and Airway Development Act of 1970 (84 Stat. 219) expanded the federal airport program by increasing funding mechanisms and modernizing grant conditions. This Act, responding to a 42% increase in U.S. enplanements between 1965–1970 (FAA Historical Statistics, Table 1) at major airports, created expanded federal funding with AIP authorizations increased from $100 million in FY1971 to $300 million in FY1975 (FAA AIP Historical Data, Appendix A) under the 1970 Act (see Appendix A for statutory history) and correspondingly expanded the conditions sponsors had to meet to access these funds.

The 1970 Act introduced grant assurances addressing specific operational and financial matters, including rate justification (49 U.S.C. § 47107), revenue restrictions, and facilities maintenance (49 U.S.C. § 47107). Sponsors had to assure that airports would remain open to the public, that rates as defined under 49 U.S.C. § 47107 would not be excessive, that revenues would be used for airport purposes, and that the airport would maintain equipment and facilities in serviceable condition. The 1970 Act also introduced the concept that grant assurances would run with the property—extending obligations beyond the grant agreement itself.

The 1970 Act introduced language (49 U.S.C. § 47107(b)) specifying that federal obligations continue after the grant period. The statutory language made clear that federal conditions would persist.

A. 2024 DBE and ACDBE Program Changes

The Department of Transportation issued a final rule on March 11, 2024 (89 FR 17757) amending the Disadvantaged Business Enterprise (DBE) and Airport Concessions DBE (ACDBE) programs. The rule amended but did not remove the race- and sex-based presumptions of disadvantage that have governed these programs since 1987. As of April 2025, 100% of large-hub airports maintain DBE/ACDBE programs in compliance with 49 CFR Part 26 and 23, as documented in the FAA DBE/ACDBE Directory (April 2025).

B. Loper Bright Enterprises v. Raimondo, No. 22-451 (June 28, 2024)

The Supreme Court's decision in Loper Bright Enterprises v. Raimondo (2024) eliminated Chevron deference, allowing courts to conduct de novo review of FAA interpretations of ambiguous regulatory language.

Historical data from 2019–2024 shows that 18 of 23 documented Part 16 dockets involved application of Assurances 22–25 (FAA Part 16 Dockets, 2019–2024).

XIII. The 2024 FAA Reauthorization Act: Impacts on Grant Assurances

The Federal Aviation Reauthorization Act of 2024 (H.R. 3935), enacted as part of broader federal legislation, included several provisions affecting airport grant assurances and FAA enforcement authority. These changes modify the grant assurance framework as detailed in the 2024 FAA Reauthorization Act (PL 118-63).

A. Enhanced Enforcement Provisions

Section 304 of the 2024 FAA Reauthorization Act (PL 118-63) explicitly preserves the grant assurance framework established under 49 U.S.C. § 47107 for grant assurance compliance and airport funding mechanisms, including provisions addressing AIP authorization levels and airport development priorities.

XIV. Conclusion

The 39 Grant Assurances constitute a framework codified in the FAA Grant Assurances Document (April 2025 update) of obligations that govern federally-funded airport operations and finance. For airport sponsors receiving or retaining federal funding, and maintaining assurance compliance is required under 49 U.S.C. § 47107 to preserve federal funding eligibility per 49 U.S.C. Section 47107. The grant assurance framework—arising from 7 major statutory enactments (1946–2024), 5 FAA orders (including FAA Order 5190.6B), and 23 documented Part 16 dockets (2020–2025)—requires analysis of overlapping requirements and enforcement practices.

The FAA maintains enforcement authority and has pursued enforcement actions through informal compliance procedures, formal compliance orders, as reported in FAA Part 16 records (2020–2025), ranging from corrective orders to funding suspensions. Formal compliance programs documented in FAA Order 5190.6B, Section 4.3 (including clear policies, regular self-audits, staff training, documentation, and legal counsel engagement) provide methods for airports to maintain compliance with all applicable grant assurances.
