The U.S. rules apply to new type certificates and modified airplanes<\/p>\n\n\n\n
Some business jets and large turboprop airplanes are included in new FAA\u00a0final rules\u00a0that enact Environmental Protection Agency-prescribed fuel efficiency certification requirements. The rules take effect on April 16 and apply to certain subsonic jet airplanes with a maximum takeoff weight greater than 5,700 kilograms (22,500 pounds) and to certain turboprop airplanes with a mtow greater than 8,618 kilograms (19,000 pounds).<\/p>\n\n\n\n
Under this final rule, an airplane is subject to these certification requirements: (1) at new (original) type certification; (2) upon manufacture of any covered airplane after Jan. 1, 2028; or (3) when a modification to a covered airplane meets fuel efficiency change criteria specified in the regulations. Exempted are piston airplanes, airplanes used for firefighting, amphibious airplanes, non-pressurized airplanes, certain specialized operations airplanes, and out-of-production airplanes currently in service.<\/p>\n\n\n\n
The new FAR Part 38, Appendix A, rule contains the certification testing methods that OEMs or modifiers must perform to determine the fuel metric value that a specific airframe design must comply with to obtain fuel efficiency certification. See also Advisory Circular 38-1. According to the FAA, the airplanes covered by the new regulations are responsible for 9 percent of domestic transportation emissions and 2 percent of total U.S. carbon pollution.<\/p>\n\n\n\n
Sixty comments were submitted and 14 generally supported the rules as proposed. Nine, including ALPA, Boeing, Gulfstream, NBAA, GAMA, and Embraer supported the rule but offered suggested changes.<\/p>\n","protected":false},"excerpt":{"rendered":"
