Charlotte Woodward Organ Transplant Discrimination Prevention Act
This bill expressly prohibits organ transplant service providers that receive federal funds and state and local government programs from denying or restricting an individual's access to organ transplants on the basis of the individual's disability, except in limited circumstances.
Specifically, these entities may not take into account an individual's disability when providing transplant services, including with respect to eligibility, referrals for services, and placement on waiting lists. Entities must provide reasonable modifications to policies or appropriate auxiliary equipment and services unless doing so changes the fundamental nature of the program or activity involved. Any consideration of an individual's disability must be based on an individualized assessment and comply with the Americans with Disabilities Act of 1990 and other applicable laws.
The Office for Civil Rights of the Department of Health and Human Services (HHS) must consider for expedited resolution complaints alleging discrimination on the basis of disability with respect to organ transplant services. HHS must annually report to Congress on complaints received and recommendations to improve enforcement of the bill.
In addition, the bill prohibits discrimination on the basis of disability in the Organ Procurement and Transplantation Network's policies regarding allocating organs. This network is a public-private partnership linking professionals involved in the U.S. organ donation and transplantation system.

Rotorcraft Operations Transparency and Oversight Reform Act or the ROTOR Act
This bill addresses aviation safety by increasing requirements for aircraft tracking and communication using Automatic Dependent Surveillance-Broadcast (ADS-B) technology and expanding oversight.
As background, ADS-B for broadcasting (Out) and receiving (In) transmits information (e.g., location and weather information) between aircraft and air traffic control.
Under the bill, aircraft must generally operate with ADS-B In equipment to provide the aircraft with location information of other aircraft and traffic advisories. Current law does not require this equipment.
Current Federal Aviation Administration (FAA) regulations allow aircraft performing a sensitive government mission to be excepted from requirements for using ADS-B Out equipment. This bill limits which flights may be considered sensitive government missions (e.g., not training flights) and requires additional reporting and notifications for the exception.
The Government Accountability Office must review the use of the ADS-B Out exception and the Office of the Inspector General (OIG) of the Department of Transportation must annually audit FAA oversight of operations that use the exception.
Further, the bill repeals a 2025 law that exempts certain military helicopters from the ADS-B Out requirements for the Washington, DC, metropolitan area.
The bill also requires
• the OIG of the Army to audit the Army’s coordination with the FAA,
• the FAA to establish an office to coordinate airspace usage of military aircraft and review the safety of flight operations and routes around airports, and
• the FAA to enter into memoranda of understanding with military agencies for safety information sharing.
