HB 24-1235: Aviation Impact Reduction

• Creates a 50% income tax credit (up to $500 per aircraft) for aircraft owners who modify planes to use unleaded aviation gasoline instead of leaded fuel, available for tax years 2025-2029.

• Requires airports in densely populated areas with significant general aviation activity to adopt plans phasing out leaded aviation gasoline sales by January 1, 2030, and establish voluntary noise abatement plans to reduce aircraft noise impacts on communities.

• Expands the Colorado Aeronautical Board from 7 to 9 voting members, adding two seats for residents of communities affected by airport traffic and one non-voting seat for the Department of Public Health and Environment.

• Designates 10% of annual aviation grant funds (up to $1.5 million per year) for projects supporting the transition from leaded to unleaded aviation fuel, prioritizing airports in urban/suburban areas.

• Appropriates $44,609 to the Department of Revenue for 2024-25 to implement the tax credit and support system changes.
