The FAA released a proposed new regulation, FAR Part 38, to establish fuel efficiency metric requirements for certain large subsonic jet and turboprop airplanes aimed at reducing greenhouse gasses. The rule would cover most civil subsonic jet airplanes with mtows greater than 12,566 pounds and turboprop airplanes with mtows great than 19,000 pounds. Essentially, Part 38 would apply to new large subsonic jets and turboprops for which a type certificate application is submitted on or after Jan. 11, 2021. Additionally, the standards would apply to airplanes for which an application for a modification in type design is submitted on or after Jan. 1, 2023. Finally, the rules would start to apply to in-production turbine aircraft that get their initial certificate of airworthiness after Jan. 1, 2028. In-service aircraft without type certificate modifications on or after Jan. 1, 2023, and no longer being manufactured are exempt. Comments on the proposal are due Aug. 15, 2022.
