## Summary

**Raises fuel taxes on non-commercial aviation to fund air-quality monitoring and transit improvements in disadvantaged communities.** This bill would sharply increase excise taxes on private and other non-commercial aircraft fuel, index part of the tax to inflation, and create a dedicated trust fund for local clean-air and transit projects. - Private and other non-commercial operators would face a much higher excise: about 36¢ plus $1.6 per gallon, with the $1.6 portion indexed to inflation beginning after 2026. Commercial aviation would pay a low rate of 4.3¢ per gallon and a narrow helicopter/tree-care exemption is tightened. - Creates the "Funding to Support Clean Communities Trust Fund" paid from specified aviation and kerosene tax receipts to finance air monitoring, sensors in low-income and disadvantaged areas, and expansion or upgrades to public transit and passenger rail within 20 miles of airports. At least 50% of annual funding must go to disadvantaged communities. - Provides a refundable credit for fuel used with reasonable cause in non-commercial cases like scientific research, evacuations, or medical emergencies. Refunds go to the purchaser without interest and apply only to fuel sold or used before Jan 1, 2028.

Manufacturers' kerosene tax would follow the same rule. From Jan…
