On September 30, 2003, we published a Notice of Proposed Rulemaking (NPRM) for proposed amendments to existing emission standards for oxides of nitrogen (NO(sub x)) for newly certified commercial aircraft gas turbine engines with rated thrust greater than 26.7 kilonewtons (kN). These proposed standards are equivalent to the existing (effective in 2004) NO(sub x) 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 NPRM also proposed to amend the test procedures for gaseous exhaust emissions to correspond to recent amendments to the ICAO test procedures for these emissions. In addition, we also took comment on applying the proposed NO(sub x) standards to newly manufactured engines of already certified models (a production cut-off).
