The Engine Fuel Venting and Exhaust Emissions rule (14 CFR part 34) applies to civil airplanes that are powered by aircraft gas turbine engines of the classes specified in the rule. The engines must have U.S. standard airworthiness certificates or foreign airworthiness certificates that are equivalent to U.S. standard airworthiness certificates.
U.S. manufactured gas turbine engines or foreign manufactured gas turbine engines that are installed in U.S. manufactured Part 23 or Part 25 aircraft must show compliance to the 14 CFR part 34 fuel venting and exhaust emissions requirements.
Regulated emissions include engine exhaust smoke (SN), hydrocarbons (HC), carbon monoxide (CO), and oxides of nitrogen (NO x), for certain classes of engines.
Responsible FAA organization
The FAA Office of Environment and Energy, AEE-300, has responsibility for maintaining the fuel venting and exhaust emissions standards of 14 CFR part 34. In addition, AEE-300 provides policy and guidance relative to this rule and promotes international harmonization of emissions standards through ICAO.
Basis of fuel venting and exhaust emissions requirements
The Clean Air Act (CAA) of 1970 directs the Environmental Protection Agency to establish air pollution standards, including those applicable to aircraft exhaust. Under Sections 231 and 232 of the CAA, EPA consults with FAA to ensure that the development and application of requisite technology is possible. FAA issues regulations under 14 CFR Part 34 to ensure compliance with EPA regulations under 40 CFR Part 87.
