ZeroAvia today announced that the Federal Aviation Administration (FAA) has published the special conditions for the company’s electric engine as a Final Rule to the Federal Register.
“This represents a major step towards type certification of ZeroAvia’s electric propulsion system and wider hydrogen-electric powertrain,” said the company in a press release. “The special conditions advance ZeroAvia’s readiness to progress through the certification process following the FAA issuing G1 and P1 issue papers last year. It caps off a run of milestones with the respective regulators overseeing the company’s certification projects, including the UK CAA awarding the company Design Organization Approval in October last year.”
Given the novelty involved in electric engines for aircraft, the special conditions contain the additional safety standards that the FAA Administrator considers necessary to establish a level of safety equivalent to that established by existing airworthiness standards.”
ZeroAvia’s electric propulsion system (EPS) combines its proprietary 600kW motor and inverter technology and is an integral part of the company’s planned full hydrogen-electric powertrain for 10-20 seat commercial aircraft, the ZA600. For the full powertrain, the EPS will be powered by multiple ZeroAvia SuperStack Flex 200kW fuel cell modules, and the company is now focused on advancing regulatory maturity of this power generation system to serve in the full powertrain, but also as a discreet product for UAV, eVTOL and general aviation applications, said ZeroAvia. The system is already being supplied to the defence sector and in active discussions with prospective civil aviation-focused OEMs.
