This bill authorizes the FAA to run a pilot program at up to four large-hub public-use airports that lets local airport operators obtain a one-time waiver to fund repair or replacement of residential sound insulation previously installed with federal assistance. It pairs that waiver with a change to how allowable project costs are calculated so earlier federal payments aren’t counted against a new project’s eligibility.
The measure targets legacy insulation installed before 2002 that has deteriorated or caused damage, and limits assistance to residences in defined noise contours that meet technical noise-auditor and interior-noise test thresholds. It also allows airports to use federal grant-allowable funds to conduct owner-requested surveys to identify eligible properties.
At a Glance
What It Does
The bill adds a special rule to 49 U.S.C. 47109 and creates a new subsection 47110(j) directing the FAA to establish a pilot allowing a one-time waiver of subsection (b)(4) for qualifying repair/replacement projects and to treat prior federal payments as excluded when calculating allowable project costs. It authorizes up to four large-hub airports to participate and allows limited surveys as an allowable cost.
Who It Affects
Large-hub public-use airports that have a local program funding secondary noise with non-aeronautical revenue, homeowners whose residences previously received federally funded sound insulation, FAA grant administrators, and firms that perform noise audits and insulation work.
Why It Matters
The bill creates a narrow pathway to remediate aging, federally funded insulation without automatically counting earlier federal expenditures against a new project's eligibility — a technical fix that reopens some federal support while imposing eligibility controls to limit exposure.

What This Bill Actually Does
The bill instructs the FAA to stand up a pilot program at up to four large-hub public-use airports within 120 days of enactment. Participation is limited to local airport operators that already run a local secondary-noise funding program financed with non-aeronautical revenue; those airports can seek a one-time waiver of a statutory requirement (subsection (b)(4)) so they may pursue repair or replacement projects for residences that previously received federal sound-insulation assistance.
To qualify, the residence must lie within the Day-Night Average Sound Level (DNL) 65–75 dB contours on the most recent FAA noise exposure map or have been within those contours when the original treatment was installed. The bill adds objective tests: a qualified noise auditor must find that the original installation either damaged the structure or used low-quality materials that have deteriorated, and interior testing must show current noise levels exceed DNL 45 dB with the prospect that a new insulation package could lower interior noise by at least 5 dB.Applicants (typically the airport operator coordinating with the property owner) must show they exhausted warranties, insurance, and legal remedies for the original installation and must verify that the federally assisted insulation was installed before 2002.
The bill also amends cost accounting: when a qualifying repair/replacement project receives the waiver, the allowable project cost calculation must exclude amounts the government previously paid for the earlier installation, which avoids double-counting prior federal expenditures when measuring the project’s eligibility.Finally, the bill authorizes the Secretary to treat periodic surveys as an allowable airport project cost so airports can, at the request of property owners, re-survey previously insulated properties to identify candidates for repair or replacement under the pilot. Surveys are limited to owner-requested properties and intended only to locate residences meeting the statutory eligibility standards.
The Five Things You Need to Know
The FAA must establish a pilot at up to four large-hub public-use airports and do so within 120 days of enactment.
The bill creates a one-time waiver of subsection (b)(4) for qualifying repair/replacement sound-insulation projects and adds 49 U.S.C. 47109(i) to exclude prior federal payments when calculating allowable project cost.
Eligible residences must be within DNL 65–75 dB on the most recent noise exposure map (or were within those contours when the original treatment was installed) and the original insulation must have been installed before 2002.
A qualified noise auditor must find structural damage or material deterioration not caused by owner negligence, interior testing must show DNL >45 dB, and the proposed new insulation must be able to produce at least a 5 dB reduction.
Applicants must exhaust warranties, insurance, and legal remedies for the original installation; airports may use grant-allowable funds to conduct owner-requested surveys to identify eligible properties.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Gives the Act the short name “Sound Insulation Treatment Repair and Replacement Program Act.” This is purely formal but is the label under which the pilot authority and grant-accounting changes will be referenced in any implementing guidance and contracts.
Special accounting rule for allowable project cost
Amends 49 U.S.C. 47109 by adding subsection (i), which instructs that for projects granted the specific waiver, the allowable project cost must be calculated “without consideration of any costs that were previously paid by the Government.” Practically, that prevents prior federal expenditures on an earlier insulation project from reducing the eligible cost base for a new repair or replacement project — a bookkeeping rule that makes a second federal contribution administratively possible without treating it as duplicative in cost-share formulas.
Pilot design and participating airports
Directs the FAA to establish a pilot at up to four large-hub public-use airports and limits participation to local airport operators that have a local program funding secondary noise with non-aeronautical revenue. The provision ties eligibility for the statutory waiver to local financial commitments for secondary-noise mitigation and confines federal participation to a small, time-limited experiment rather than broad programmatic change.
Applicant and property eligibility criteria
Sets the technical eligibility gate: properties must lie within DNL 65–75 dB contours (current or at project installation), show prior federally assisted insulation installed before 2002, and satisfy auditor findings that the prior treatment caused physical damage or degraded due to low-quality materials. It also requires interior noise testing above DNL 45 dB and a demonstrable potential for a 5 dB improvement. The section mandates exhaustion of warranties, insurance, and legal remedies before federal assistance is available, allocating primary responsibility for pursuing other remedies to applicants and owners.
Survey authority and limits
Allows the Secretary to treat periodic owner-requested surveys as an allowable cost for airports that previously received federal assistance on the property. Surveys are scoped narrowly: airports may only survey properties where a property owner has expressed interest, and the surveys are intended to identify repair/replacement candidates rather than to create broad inventories. This provision creates a limited, grant-eligible path for outreach and diagnostics tied to the pilot.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Homeowners in affected noise contours whose earlier federally assisted insulation predates 2002 — eligible homeowners gain access to a targeted federal pathway for repair or replacement when deterioration or damage has rendered the original treatment ineffective.
- Large-hub airports with non-aeronautical secondary-noise funding programs — those airports can apply for the pilot waiver, leverage federal guidance on surveys, and potentially lower local community noise burdens without having prior federal payments automatically disqualify projects.
- Noise-abatement planners and local governments in participating metro areas — the pilot offers updated data from surveys and auditors to inform local mitigation priorities and strengthens cooperation between airports and communities.
- Contractors and certified noise auditors — new demand for inspection, testing, and remedial construction work will flow from eligible repair and replacement projects in pilot locations.
Who Bears the Cost
- Federal government / FAA — although the bill narrows eligibility, changing allowable-cost accounting and granting waivers opens the possibility of additional federal disbursements for projects that previously received federal support, and FAA will incur oversight and administrative costs implementing the pilot.
- Participating airports — they must have (or create) a local program funded with non-aeronautical revenue to qualify and will carry costs for outreach, surveys, and program coordination; they also must coordinate warranty/insurance/legal diligence before pursuing federal assistance.
- Property owners — owners must pursue warranties, insurance, and legal remedies first and pay for any up-front testing or repairs not covered by those avenues; they may also bear the burden of documentation and access for audits and surveys.
- Local procurement and compliance teams — meeting the bill’s auditor qualifications, test protocols, and documentation standards will add procurement, contracting, and compliance work for small airport teams and local governments.
Key Issues
The Core Tension
The central dilemma is between correcting an identifiable legacy problem — degraded or damaging sound insulation that the federal government originally funded — and avoiding a precedent that reopens federal responsibility (and cost exposure) for long-term maintenance or replacement of previously funded improvements; helping homeowners now may be justified, but doing so risks creating ongoing federal expectations for future repairs.
The bill solves a narrow administrative problem — how to permit additional federal help for residences that previously received federal insulation — but it leaves several operational questions unresolved. The statute does not define “qualified noise auditor,” which creates potential variability in who can certify damage or deterioration and how tests are conducted.
The DNL and interior-noise thresholds (DNL 65–75 exterior contour; interior DNL >45 with a 5 dB achievable reduction) embed technical trade-offs: small differences in measurement protocol or changes in contour mapping over time could move properties in or out of eligibility.
Limiting the pilot to up to four large-hub airports and to properties where owners express interest focuses resources but risks selection bias and equity gaps: many communities with aging insulation may never be covered. The exhaustion-of-remedies requirement protects against trivial claims but shifts investigative and legal costs to property owners and airports.
Finally, while 47109(i) excludes previous federal payments from allowable-cost calculations to enable a new federal contribution, that accounting change does not resolve larger policy questions about federal ongoing liability for maintenance and the risk of incentivizing lower-quality original installations if later remediation is treated as a federal option.
