This bill authorizes the Administrator of the Federal Aviation Administration (FAA) to establish a pilot program at up to four large hub public-use airports to provide federal assistance for the repair and replacement of residential sound insulation . This program targets homes where sound insulation, previously installed with federal or federally authorized airport assistance, has deteriorated, broken, or caused physical damage and no longer functions as intended. To qualify, residences must fall within specific Day Night Level (DNL) 65 to 75 decibel noise contours and demonstrate current interior noise levels exceeding DNL 45 dB, with new insulation capable of achieving a 5 dB reduction. The original sound insulation must have been installed prior to 2002 , and a qualified noise auditor must determine its condition is not due to the property owner's negligence; applicants must also exhaust other remedies like warranties. The bill amends existing law to allow a one-time waiver of certain cost-sharing requirements for qualifying airports, enabling new federal assistance for these projects without considering previously paid government costs. It also authorizes the Secretary to consider costs for airports to conduct periodic surveys of properties that received repair or replacement, helping identify homes eligible for further assistance.
