The Aviation Funding Stability Act of 2025 gives the Federal Aviation Administration temporary access to the Airport and Airway Trust Fund (AATF) when Congress fails to enact FAA appropriations or a continuing resolution by the start of the fiscal year. The statute directs that funds be available for continuing FAA programs that were funded in the previous fiscal year.
This measure matters because it prioritizes continuity of aviation operations—air traffic control, airport grants, research, and facilities spending—during short-term funding lapses, while shifting near-term fiscal responsibility onto a user-funded trust rather than the general fund or emergency congressional action.
At a Glance
What It Does
The bill makes amounts in the Airport and Airway Trust Fund available to the FAA to continue programs that had funding in the prior fiscal year, including operations, facilities and equipment, research, and grants-in-aid. Funding under this authority is limited to a short window and capped at the prior year’s rate for operations.
Who It Affects
Directly affects the FAA, airports receiving AIP grants, and other beneficiaries of FAA programs; it also affects the AATF itself and parties who rely on it (airlines, general aviation, and airport capital projects). Congressional appropriators and Treasury/agency accounting offices will face practical implications.
Why It Matters
The bill creates a standing, statutory backstop for aviation financing in a lapse, reducing immediate operational disruption but setting a precedent for using a dedicated trust fund to substitute for annual appropriations—altering leverage in budget standoffs and the timing of aviation investments.

What This Bill Actually Does
If enacted, the Act authorizes the FAA Administrator to draw on the Airport and Airway Trust Fund whenever Congress does not pass a regular appropriations act or a continuing resolution for the FAA by the start of the fiscal year. The authority covers continuing programs, projects, and activities that received funding in the preceding fiscal year, and expressly includes costs associated with direct loans and loan guarantees.
The statute ties available programs to those listed in the prior year appropriations measure or the prior year continuing resolution.
Money used under this authority is limited in several ways. The bill caps funding at a ‘‘rate for operations’’ no greater than the rate provided in the prior fiscal year’s regular appropriation act (or the prior year continuing resolution if there was no enacted appropriation).
The availability window begins on the first day of the lapse and ends either when a regular appropriation or continuing resolution for the current year becomes law, or 30 days after the lapse begins—whichever comes first. If the provision is in effect at the end of a fiscal year, it continues to operate into the following fiscal year until the same end triggers occur.Administrative mechanics are built into the text: obligations and expenditures made under the AATF authority will be charged to the applicable appropriation or authorization once Congress subsequently enacts the regular appropriations or a continuing resolution.
The bill also amends the Internal Revenue Code (section 9502(d)(1)(A)) to list this Act alongside other laws that permit trust fund expenditures during lapses, so agencies and Treasury treat the authority as a statutory exception to a funding lapse.Finally, the Act contains a carve-out: it does not apply to any program or activity for which some other law (outside of authorization language) either already provides funding or expressly forbids an appropriation for the period in question. That preserves prior express statutory funding arrangements and limits clashes with other statutes.
The Five Things You Need to Know
The bill limits AATF-driven funding to the FAA for a lapse to a maximum of 30 days from the start of the lapse unless Congress enacts an appropriation or continuing resolution sooner.
Covered accounts are explicit: Operations; Facilities and Equipment; Research, Engineering, and Development; and Grants-in-Aid for Airports, plus costs of direct loans and loan guarantees.
Funding under the Act is constrained to the prior fiscal year’s rate for operations—the bill bars using a higher operational rate than what applied in the preceding year’s enacted appropriation or continuing resolution.
The Act amends Internal Revenue Code section 9502(d)(1)(A) to name this statute as a lawful trigger for trust fund expenditures during an appropriations lapse, aligning Treasury practice with the new authority.
Expenditures made under the AATF authority must later be charged to the applicable regular appropriation, fund, or authorization once Congress enacts the relevant appropriation or continuing resolution, creating a post-facto accounting reconciliation.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Gives the bill the name 'Aviation Funding Stability Act of 2025.' This is purely formal but indicates the policy focus and will appear in statutory citations if enacted.
General availability of AATF during lapse
Authorizes the Administrator to use Airport and Airway Trust Fund amounts that are not already appropriated to continue FAA programs and projects that were funded in the prior fiscal year. Practically, this ties eligibility for emergency funding to last year’s funding footprint rather than creating open-ended new authorities.
Rate-for-operations limit
Requires that any appropriations or authority provided under the Act must be at a rate for operations no greater than the rate provided in the previous fiscal year’s enacted appropriation (or prior continuing resolution if no appropriation was enacted). This clamps spending to prior-year operational levels and prevents upward adjustments during the lapse.
Duration and 30‑day cap
Specifies the availability period: beginning the first day of the lapse and ending either when a regular appropriation or continuing resolution becomes law or 30 days after the lapse begins. The 30-day hard stop creates a short-term bridge rather than indefinite funding until appropriation.
Terms and conditions carryover
Mandates that funds made available under this authority remain subject to the terms, conditions, and legal restrictions that applied to the preceding fiscal year’s appropriations or continuing resolution. Agencies cannot use AATF money on looser terms than last year’s law permitted.
Effect at fiscal-year boundary
States that if the Act is active at the end of a fiscal year, the funding rules continue into the next fiscal year. That prevents an abrupt cutoff on October 1 if a lapse spans a fiscal-year change, but it also extends the trust‑fund drawdown across fiscal years until an appropriation is passed or the 30‑day rule is triggered.
Chargeback to eventual appropriation
Directs that obligations and expenditures incurred under this authority will be charged to the applicable appropriation, fund, or authorization once Congress later enacts the regular appropriation or a continuing resolution. This requires post‑lapse accounting reconciliation between the FAA and Congress.
Internal Revenue Code amendment
Amends IRC section 9502(d)(1)(A) by adding this Act to the list of statutes that allow trust fund expenditures during lapses. That is an administrative fix to ensure Treasury and agencies treat the authority as a lawful exception when moving cash from the trust fund.
Termination/exception clause
Carves out any program, project, or activity already funded or explicitly barred by another provision of law from receiving funding under this Act during the lapse. This avoids creating conflicts with other statutory funding schemes or prohibitions.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Air travelers and shippers — They gain continuity in air traffic control and fewer disruptions during short funding lapses because FAA operations are funded without interruption.
- FAA personnel and contractors — Operational pay, staffing, and contract performance for mission‑critical services are protected during the statutory window, reducing immediate furlough risk.
- Airport grant recipients (AIP beneficiaries) — The inclusion of Grants‑in‑Aid for Airports in the covered accounts lets ongoing grant-supported projects continue for the statutory period, avoiding project stoppages.
- Commercial airlines and cargo carriers — Short-term continuity in ATC and facilities reduces the chance of delays and cancellations tied to a lapse, protecting scheduled operations and supply chains.
- State, local, and regional aviation authorities — Those that rely on FAA-funded programs and grants receive a brief, predictable funding bridge that limits administrative and operational uncertainty.
Who Bears the Cost
- Airport and Airway Trust Fund balance — The trust fund will absorb the cash outflows during lapses, reducing reserves otherwise available for late-year projects or multi‑year planning.
- Congressional appropriators — Using the trust fund as a backstop reduces short-term budget leverage Congress holds during shutdown standoffs and could complicate negotiations over FAA appropriations.
- Department of Transportation and FAA financial offices — Agencies must implement new accounting, chargeback procedures, and reconciliations when appropriations are later enacted, increasing administrative workload.
- Future airport projects and capital planning — If the trust fund is drawn down during repeated lapses, later-year AIP awards or discretionary projects could face funding pressure, timing shifts, or prioritization disputes.
- Treasury and tax administration — The IRC amendment requires coordination in fund flow rules and could create short-term administrative changes for how trust fund disbursements are processed and reported.
Key Issues
The Core Tension
The central dilemma is between two valid objectives: preserving uninterrupted aviation operations during short-term funding lapses and protecting Congress’s annual appropriations authority and the integrity of the Airport and Airway Trust Fund. The Act secures immediate operational stability at the cost of drawing down a dedicated user-funded reserve and shifting budgetary leverage away from appropriators—an outcome that has fiscal, administrative, and constitutional implications with no neat resolution.
The bill trades immediate operational continuity for pressure on a statutorily dedicated trust fund. Using AATF cash to substitute for annual appropriations runs straight into two practical problems: it reduces the fund’s available balance for other obligations and it establishes a precedent that could be invoked again, with cumulative fiscal effects.
Administratively, the requirement to charge expenditures to later appropriations forces post‑lapse reconciliation work and raises questions about how Congress will treat those charges when setting final year-end allocations.
Legally and politically, the Act blurs lines between Congress’s power of the purse and reliance on user‑fee financed trust funds. While the 30‑day cap limits the exposure, that cliff can create its own operational risk: agencies will face renewed pressure at day 31 if no appropriation is in place, and airlines/airports may still encounter planning uncertainty.
The law’s exceptions (programs already funded or expressly barred) reduce collisions with other statutes but introduce complexity about which activities qualify in practice, likely requiring formal guidance and OMB/Treasury coordination.
