US HB5155

Prohibits federal agencies from entering procurement contracts unless contractors agree in writing to provide the Department of Defense fair and reasonable access to all repair materials, including parts, tools, and diagnostic information used by manufacturers or authorized repair providers

Requires "fair and reasonable access" to mean terms equivalent to the most favorable prices and conditions offered to authorized repair providers, including discounts, rebates, and timely delivery

Allows agency heads to waive the requirement for contracts related to programs that began before enactment, provided they submit justification to congressional defense committees based on an independent technical risk assessment of cost, schedule, and performance impacts

Directs the Secretary of Defense to review existing contracts and identify modifications needed to remove intellectual property constraints that limit DoD's ability to conduct maintenance and access repair materials

Requires the Comptroller General to submit a report to congressional defense committees within 1 year on DoD's implementation and compliance with the new requirements
