Department of Transportation Federal Aviation Administration • 14 CFR Part 21 • [Docket No. FAA-2021-0638] ( printed page 17230) AGENCY: Federal Aviation Administration (FAA), DOT ACTION: Issuance of final airworthiness criteria. SUMMARY: The FAA announces the special class airworthiness criteria for the Joby Aero, Inc. (Joby) Model JAS4-1 powered-lift. This document sets forth the airworthiness criteria the FAA finds to be appropriate and applicable for the powered-lift design. DATES: These airworthiness criteria are effective April 8, 2024. FOR FURTHER INFORMATION CONTACT: James Clary, Emerging Technology Coordination Section, AIR-611, Policy and Standards Division, Aircraft Certification Service, Federal Aviation Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177; telephone 817-222-5138; email james.clary@faa.gov. SUPPLEMENTARY INFORMATION: Background The Joby Model JAS4-1 (Model JAS4-1) powered-lift has a maximum gross takeoff weight of 4,800 lbs. and is capable of carrying a pilot and four passengers. The aircraft uses six tilting electric engines with 5-blade propellers attached to a conventional wing and V-tail.[1] The aircraft structure and propellers are constructed of composite materials. As a powered-lift, the Model JAS4-1 has characteristics of both a rotorcraft and an airplane. The Model JAS4-1 is intended to be used for Title 14, Code of Federal Regulations (14 CFR) parts 91 and 135 operations, with a single pilot onboard, under visual flight rules (VFR). On November 2, 2018, Joby applied for a type certificate for the Model JAS4-1 powered-lift. Under 14 CFR 21.17(c), Joby's application for type certification is effective for three years. Section 21.17(d) provides that, where a type certificate has not been issued within that three-year time limit, the applicant may file for an extension and update the designated applicable regulations in the type certification basis. Because the project was not certificated within three years after the application date above, the FAA approved the applicant's request to extend the application for type certification. As a result, the date of the updated type certification basis is June 14, 2022. The FAA issued a notice of proposed airworthiness criteria for the Model JAS4-1 powered-lift, which published in the Federal Register on November 8, 2022 (87 FR 67399). The FAA issued a notice extending the comment period to December 22, 2022, which published in the Federal Register on December 7, 2022 (87 FR 74994). Discussion Because the FAA has not yet established powered-lift airworthiness standards in 14 CFR, the FAA type certificates powered-lift as special class aircraft. Under the procedures in § 21.17(b), the airworthiness requirements for special class aircraft, including the engines and propellers installed thereon, are the portions of the requirements in 14 CFR parts 23, 25, 27, 29, 31, 33, and 35 found by the FAA to be appropriate and applicable to the specific type design and any other airworthiness criteria found by the FAA to provide an equivalent level of safety to the existing standards. These final airworthiness criteri…
