Title: Harmonization of Airworthiness Standards--Miscellaneous Structures Requirements | |
Abstract: This rulemaking would eliminate regulatory differences between the transport category aircraft airworthiness standards of the FAA and European Aviation Safety Agency (EASA) by revising the structural test requirements necessary when analysis has not been found reliable; clarifying the quality control, inspection, and testing requirements for critical and non-critical castings; adding control system requirements that consider structural deflection and vibration loads; expanding the fuel tank structural and system requirements regarding emergency landing conditions and landing gear failure conditions; adding a requirement that engine mount failure due to overload must not cause hazardous fuel spillage; and revising the inertial forces requirements for cargo compartments by removing the exclusion of compartments located below or forward of all occupants in the airplane. This action is based on recommendations from the Aviation Rulemaking Advisory Committee (ARAC). The intended effect is for future certificated transport airplanes to meet one single set of requirements. | |

Additional Information: No costs are associated with this proposed rule because all manufacturers of transport category airplanes, certified under part 25, are expected to continue their current practice of compliance 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 rule. They may in fact receive cost-savings because they will not have to build and certificate transport category airplanes to two different authorities’ certification specifications, paperwork requirements, and rules. | |
