Control of Air Pollution From Aircraft and Aircraft Engines; Emissions Standards and Test Procedures

Abstract: This rulemaking would amend the existing United States regulations governing the exhaust emissions from new commercial aircraft gas turbine engines. This action would adopt standards equivalent to the NOx standards of the United Nations International Civil Aviation Organization (ICAO), and thereby bring the United States emission standards into alignment with the internationally adopted standards. The action would also adopt updated ICAO recommended practices such as amended test procedures and definitions. These NOx standards and recommended practices were adopted by ICAO's Committee on Aviation Environmental Protection (CAEP) in 2004 and 2010. The proposed rule would establish consistency between United States and international requirements.
