In a final rule, the U.S. Environmental Protection Agency (EPA) is replacing the existing smoke standard on civil subsonic jet airplanes with rated engine outputs exceeding 26.7 kilonewtons (6,002 pounds of thrust) with particle matter (PM) standards. These standards apply to in-production engines manufactured on or after Jan. 1, 2023, as well as type designs with initial type certification applications submitted on or after that same date.
