Rule Summary

EPA is amending the existing emission standards for oxides of nitrogen (NO_x) for new commercial aircraft engines. These standards are equivalent to the NO_x emission standards of the United Nations International Civil Aviation Organization (ICAO), and thereby will bring United States aircraft standards into alignment with the international standards. These standards will go into effect on December 19, 2005 and they will apply to new aircraft engines utilized on commercial aircraft that include small regional jets, single-aisle aircraft, twin-aisle aircraft, and 747s and larger aircraft.
