7 April 2026ZeroAvia 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.
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. As the world’s only hydrogen-electric focused Design Organization Approval OEM, ZeroAvia has demonstrated it has the maturity, processes and procedures to provide confidence to regulators that it can comply with stringent requirements.
