Department of Transportation Federal Aviation Administration • 14 CFR Part 25 • [Docket No. FAA-2022-0205; Special Conditions No. 25-844-SC] ( printed page 2126) AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final special conditions. SUMMARY: These special conditions are issued for the Airbus Model A319-133 and A321-200 series airplanes. These airplanes, as modified by Lufthansa Tecknik AG (Lufthansa), 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 the installation of an uninterruptible power supply (UPS) system based on supercapacitor technology. The current 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 January 12, 2024. FOR FURTHER INFORMATION CONTACT: Daniel Poblete, Electrical Systems, AIR-626A, Technical Policy Branch, Policy and Standards Division, Aircraft Certification Service, Federal Aviation Administration, 3960 Paramount Blvd., Suite 100, Lakewood, CA 90712-4137; telephone and fax (562) 627-5335; email daniel.d.poblete@faa.gov. SUPPLEMENTARY INFORMATION: Background On February 17, 2021, Lufthansa applied for a supplemental type certificate for the installation of a UPS system in the Model A319-133 and A321-200 series airplanes. The Airbus Model A319-133 and A321-200 series airplanes are twin-engine, transport category airplanes. The Airbus Model A319-133 airplane has a maximum passenger seating capacity of 160, and a maximum takeoff weight of 154,322 pounds. The Airbus Model A321-200 airplane has a maximum passenger seating capacity 230, and a maximum takeoff weight of 213,848 pounds. Type Certification Basis Under the provisions of title 14, Code of Federal Regulations (14 CFR) 21.101, Lufthansa must show that the Model A319-133 and A321-200 series airplanes, as changed, continue to meet the applicable provisions of the regulations listed in Type Certificate 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 the Airbus Model A319-133 and A321-200 series 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 applicant apply for a supplemental type certificate to modify any other model included on the same type certificate 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, the Airbus Model A319-133 and A321-200 series airplanes must comply with the fuel vent and exhaust emission requirements of 14 CFR part 34 and the noise certification requirements of 14 CFR part 36. The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with &sec…
