DOT/FAA RIN: 2120-AK12 Publication ID: Fall 2013 
Title: Harmonization of Airworthiness Standards-Gust and Maneuver Load Requirements 
Abstract: This rulemaking would revise the manufacturing design requirements for transport category aircraft; specifically, the design criteria for calculating gust and maneuver loads, as well as engine failure loads. The revisions would allow for the determination of the appropriate gust loads during the design phase of the aircraft to account for the effects of new flight control systems, and the increased weights and sizes of modern aircraft and engines. These requirements would be consistent with current requirements already imposed on manufacturers seeking aircraft certification through EASA. These revisions are further supported by FAA´s Aviation Rulemaking Advisory Committee, which was tasked with reviewing and suggesting areas to eliminate differences between EASA and FAA transport category aircraft certification standards. Thus, this rulemaking would benefit manufacturers who would only need to consider one single set of certification requirements in designing transport category aircraft.

Additional Information: No costs are associated with this action because all manufacturers of transport category airplanes, certified under part 25, are expected to continue their current practice of compliances under both part 25 and EASA's CS-25. Since this rule simply adopts the same requirements as CS-25, FAA estimates that manufacturers would not incur additional costs resulting from this action. They may receive cost savings because they will not have to build and certificate transport category airplanes to two different certification standards.
Regulatory Flexibility Analysis Required: No  Government Levels Affected: Federal 
Small Entities Affected: No  Federalism: No 
Included in the Regulatory Plan: No 
International Impacts: This regulatory action will be likely to have international trade and investment effects, or otherwise be of international interest.
