Department of Transportation Federal Aviation Administration • 14 CFR Part 25 • [Docket No. FAA-2017-1141; Special Conditions No. 25-710A-SC] AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Final special conditions, amendment. SUMMARY: These amended special conditions are issued for non-rechargeable lithium-ion battery installations on the Dassault Aviation (Dassault) Model Falcon 6X airplane. Non-rechargeable lithium-ion batteries are a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. 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: This action is effective on Dassault on March 9, 2022.

SUPPLEMENTARY INFORMATION: Background On July 1, 2012, Dassault applied for special conditions for non-rechargeable lithium-ion batteries installed in the Model Falcon 5X airplane. Special conditions were issued for that design on January 16, 2018 (83 FR 2032). However, Dassault has decided not to release an airplane under the model designation Falcon 5X, instead choosing to change that model designation to Falcon 6X. In February of 2018, due to engine supplier issues, Dassault extended the type certificate application date for its Model Falcon 5X airplane under new Model Falcon 6X. This amendment to the original special conditions reflects the model-name change. This airplane is a twin-engine business jet with seating for 19 passengers and a maximum takeoff weight of 77,460 pounds. The Dassault Model Falcon 6X airplane design remains unchanged from the Model Falcon 5X in all material respects other than different engines. The FAA is issuing these special conditions for non-rechargeable lithium-ion battery installations on the Dassault Model Falcon 6X airplane. The FAA's design standards in title 14, Code of Federal Regulations (14 CFR) part 25 are inadequate for addressing an airplane with non-rechargeable lithium-ion batteries. Type Certification Basis Under the provisions of 14 CFR 21.17, Dassault must show that the Model Falcon 6X airplane meets the applicable provisions of part 25, as amended by Amendments 25-1 through 25-146. If the Administrator finds that the applicable airworthiness regulations ( i.e.,14 CFR part 25) do not contain adequate or appropriate safety standards for the Dassault Model Falcon 6X airplane 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 airplane 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, these special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness re…
