ZeroAvia has announced that the Federal Aviation Administration (FAA) has published the special conditions for the company’s electric engine as a Final Rule in the Federal Register. This represents a major step toward type certification of ZeroAvia’s electric propulsion system and its broader hydrogen-electric powertrain.
The special conditions advance ZeroAvia’s readiness to progress through the certification process following the FAA’s issuance of G1 and P1 issue papers last year. This milestone follows a series of regulatory achievements, including the UK Civil Aviation Authority (CAA) awarding the company Design Organization Approval in October last year.
Given the novelty of electric engines for aircraft, the special conditions contain additional safety standards that the FAA Administrator considers necessary to establish a level of safety equivalent to existing airworthiness standards. As the world’s only hydrogen-electric focused Design Organization Approval OEM, ZeroAvia has demonstrated the maturity, processes, and procedures necessary to provide regulators with confidence in its ability to comply with stringent requirements.
Val Miftakhov, Founder and CEO of ZeroAvia, stated:
“Having special conditions for our electric propulsion system published by the FAA is an enormous achievement that underscores the aerospace maturity of our organization and illuminates our path forward toward type certification. It’s rapid progress from both industry and regulators that bodes well for advancing the electric age of flight.”
ZeroAvia’s electric propulsion system (EPS) combines the company’s proprietary 600kW motor and inverter technology and is an integral part of its planned full hydrogen-electric powertrain for 10-20 seat commercial aircraft, designated the ZA600. For the full powertrain, the EPS will be powered by multiple ZeroAvia SuperStack Flex 200kW fuel cell modules. The company is now focused on advancing the regulatory maturity of this power generation system for use in the full powertrain, as well as a discrete product for UAV, eVTOL, and general aviation applications.
ZeroAvia has established unique, advanced testing capabilities, including a 700kW dynamometer electric engine test rig, a segregated hydrogen fuel cell and thermal management system test environment, a hydrogen management system facility, and a state-of-the-art data acquisition setup.
Val Miftakhov concluded: “The fundamentals have not changed – electric aircraft are better aircraft with zero emissions, less noise, and better operating economics, and hydrogen is key to unlocking practical range and endurance. What we are seeing now is real momentum in terms of airframe development and fuel production. It is the beginning of the transformation in earnest.”
