The FAA this week provided valuable insight into how it intends to certify new eVTOL aircraft when it published the airworthiness criteria it is using for Joby’s JAS4-1 five-seat model. The proposed rule published in the Federal Register on November 8 marks the first time the U.S. air safety regulator has shown the specifics of the type certification requirements for the new class of electric aircraft. The agency is seeking comments on its FAA-2021-0638 proposals by Dec. 8, 2022.
The publication confirms that Joby’s aircraft is intended to be operated under both commercial Part 135 and private Part 91 rules with a single pilot on board and under visual flight rules. The California-based manufacturer applied for certification under 14 CFR 21.17 rules in November 2018 and because the process was not completed within the defined three-year period, the basis for type certification was subsequently updated in June 2022.
In a letter sent to shareholders on November 2 to report on the third quarter, Joby said that it now expects to complete the second stage of type certification by the end of 2022. However, the company also disclosed that it anticipates the start of commercial air taxi operations will slip from 2024 into 2025 as the FAA is now not expected to confirm its operational requirements for eVTOL aircraft until late 2024. Nonetheless, initial military operations for U.S. defense customers could still get underway in 2024.
