H.R. 4383

Congressional Research Service summary, version: Introduced in House (Jul 14, 2025)

Sound Insulation Treatment Repair and Replacement Program Act

This bill establishes a pilot program to allow airports to repair and replace sound insulation in residential buildings using funds provided under the Airport Improvement Program (AIP). Currently, airports may use AIP funds for one-time sound insulation projects for residential buildings.

Under the bill, the Federal Aviation Administration must establish a pilot program to allow up to four airports to have a one-time waiver to use AIP funds for the repair and replacement of sound insulation in residential buildings if the airport previously received federal assistance or federally authorized airport assistance for the insulation.

For a property to qualify under the waiver, additional requirements include that

• the insulation previously installed was done prior to 2002 and has resulted in structural deterioration;

• interior and exterior sound decibel levels for the residence meet certain criteria;
