FAA has 11,389 project schedules and no integrated master schedule for its accelerated ATC modernization.
GAO says the individual schedules are not integrated, so same-site installations are generally not optimized to reduce impacts on controller operations.
What happened
The Federal Aviation Administration's Brand New Air Traffic Control System initiative is intended to accelerate replacement of aging communication, surveillance, weather, and training systems. Phase one is planned for completion by December 2028, and Congress appropriated $12.5 billion in July 2025 to support the effort.
GAO reported on September 14 that FAA has not developed a comprehensive, well-documented lifecycle cost estimate or an integrated phase-one master schedule. Instead, FAA maintains 11,389 individual project schedules that are not integrated; GAO said installations at the same sites are therefore generally scheduled without optimizing the sequence to reduce controller impacts.
Why CMCoE cares
A modernization program this interdependent needs one view of sequencing, resource conflicts, site access, and operational impacts. Without it, speed at the project level can create collisions at the program level and increase the risk of disruption, delay, and cost growth.
Regulatory fine print
FAA does have individual project schedules, and GAO also documented progress such as replacing 2,560 of 5,170 old copper wires as of May 2026. The finding is that those schedules are not integrated into a master schedule; it is not a claim that the agency has no plans or has already caused a specific incident.
