## Abstract

This document revises the emission standards for turbine engine powered airplanes to incorporate the current standards of the International Civil Aviation Organization (ICAO) for gaseous emissions of oxides of nitrogen (No<INF>X</INF>) and carbon monoxide (CO), and to adopt revised test procedures for gaseous emissions. This rule will bring the United States emissions standards into alignment with the standards of ICAO. Because, this rule is consistent with international standards, an emission certification test that meets U.S. requirements will meet ICAO requirements.
