The FAA has published a notice of proposed rulemaking (NPRM) that will require aircraft manufacturers to improve fuel efficiency targets for a wide range of turbine, turboprop, and piston aircraft—both those still on the drawing board as well as those currently type certificated and those to be manufactured as of January 1, 2028.
The NPRM states the purpose of the proposed rule is to set “fuel efficiency requirements for certification of certain airplanes. These certification requirements would implement the emissions standards adopted by the Environmental Protection Agency, allowing manufacturers to certificate their aircraft for fuel efficiency in the United States, and fulfilling the statutory obligations of the FAA under the Clean Air Act.”
