Department of Transportation Federal Aviation Administration • 14 CFR Part 33 • [Docket No. FAA-2023-0587; Special Conditions No. 33-030A-SC] AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final special conditions, amendment. SUMMARY: This action amends the applicability of special conditions that were issued for the Safran Electric & Power S.A. Model ENGINe US100A1 electric engines. These engines have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards applicable to aircraft engines. The design feature is the use of an electric motor, motor controller, and high-voltage systems as the primary source of propulsion for an aircraft. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. This action amends the applicability of Special Conditions No. 33-23-01-SC, dated December 27, 2024, which 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, to include the ENGINe US100 series electric engines. DATES: Effective January 27, 2026.

SUPPLEMENTARY INFORMATION: Background On November 27, 2020, Safran applied for FAA validation of their pending EASA type certificate application for the Model ENGINe US100A1 electric engine. The FAA published a Notice of Proposed Special Conditions for public comment in the Federal Register on March 20, 2024 (89 FR 19763). On December 27, 2024, the FAA issued Final Special Conditions No. 33-23-01-SC (89 FR 105432) for the US100A1 electric engine. Safran subsequently amended its EASA application to include the models US100B1 and US100B2. Similarly, on January 15, 2025, Safran amended their FAA application to include the B1 and B2 on the requested type certificate for the ENGINe US100 electric engines. This amendment to the special conditions updates the applicability of Special Conditions No. 33-23-01-SC from Safran Electric & Power S.A. “Model ENGINe US100A1 Electric Engines” to “ENGINe US100 Series Electric Engines”. The novel or unusual design of these additional models is adequately addressed by the requirements of Special Conditions No. 33-23-01-SC, and the requirements of these special conditions are substantively unchanged. However, the ( printed page 3361) FAA is amending the Special Conditions number for these final special conditions from Special Conditions No. 33-23-01-SC to Special Conditions No. 33-030A-SC. Type Certification Basis Under the provisions of 14 CFR 21.17(a)(1) Safran must show that ENGINe US100 series electric engines meet the applicable provisions of 14 CFR part 33 in effect on the date of application for a type certificate. If the Administrator finds that the applicable airworthiness regulations ( e.g., part 33) do not contain adequate or appropriate safety standards for the Safran ENGINe US100 series electric engines b…
