Department of Transportation Federal Aviation Administration • 14 CFR Part 25 • [Docket No. FAA-2024-2570; Special Conditions No. 25-875-SC] AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final special conditions. SUMMARY: These special conditions are issued for the Airbus Model A321neo ACF and A321neo XLR airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. This design feature is a single-occupant oblique seat with an airbag and 3-point or pretensioner restraint system positioned at a 49-degree angle from the cabin centerline. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. DATES: Effective February 5, 2025. FOR FURTHER INFORMATION CONTACT: Shannon Lennon, Cabin Safety Section, AIR-624, Technical Policy Branch, Policy and Standards Division, Aircraft Certification Service, Federal Aviation Administration, 2200 South 216th Street, Des Moines, WA 98198; telephone (206) 231-3209; email Shannon.Lennon@faa.gov. SUPPLEMENTARY INFORMATION: Background On April 6, 2022, Airbus SAS applied for an amendment to Type Certificate (TC) No. A28NM for the installation of a single-occupant oblique seat with an airbag and 3-point or pretensioner restraint system, positioned at a 49-degree angle from the cabin centerline in new Airbus Model A321neo ACF and A321neo XLR airplanes. Airbus Model A321neo ACF and A321neo XLR airplanes, which are derivatives of the Model A321 currently approved under TC No. A28NM, are twin-engine, transport category airplanes with a maximum passenger capacity of 244. The maximum takeoff weight of the Airbus Model A321neo ACF is approximately 213,848 pounds, while the Airbus Model A321neo XLR has a maximum takeoff weight of approximately 222,667 pounds. Type Certification Basis Under the provisions of 14 CFR 21.101, Airbus SAS must show that the Model A321neo ACF and A321neo XLR airplanes, as changed, continue to meet the applicable provisions of the regulations listed in TC No. A28NM or the applicable regulations in effect on the date of application for the change, except for earlier amendments as agreed upon by the FAA. If the Administrator finds that the applicable airworthiness regulations ( e.g.,14 CFR part 25) do not contain adequate or appropriate safety standards for Airbus Model A321neo ACF and A321neo XLR airplanes because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same novel or unusual design feature, or should any other model already included on the same type certificate be modified to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, Airbus Model A321neo ACF and A321neo XLR airplanes must comply with t…
