Airport Improvement Program (AIP) grant assurances

The FAA has proposed updates to its Airport Improvement Program (AIP) grant assurances to reflect new requirements from the FAA Reauthorization Act of 2024 and recent executive orders. Key changes include removing older equity- and climate-related executive orders, adding new ones focused on free speech and ending DEI programs, and introducing a new assurance requiring airports to continue offering leaded aviation fuel (100LL) until a safe unleaded replacement is widely available. Public comments on these changes were accepted through May 9, 2025.

Notes

The FAA proposes updates to the Airport Improvement Program (AIP) grant assurances to reflect provisions in the FAA Reauthorization Act of 2024 and recently issued executive orders. Changes include removal of several Obama-era executive orders, addition of new Trump administration executive orders, and updates to grant assurance provisions on civil rights, airport layout plans, and access to leaded aviation fuel. The FAA is implementing these modifications immediately upon publication while accepting public comments for 14 days.
