ZeroAvia’s 600kW hydrogen-electric propulsion system has received a G-1 Issue Paper from the US Federal Aviation Administration (FAA), confirming the certification basis and outlining its path to full approval and commercialisation.
The Issue Paper defines the airworthiness regulations the system must meet and support ZeroAvia’s efforts to certify its full hydrogen-electric powertrain with the UK Civil Aviation Authority (CAA).
By establishing these regulatory requirements, ZeroAvia is now able to validate its design and move forward in the approval process.
CEO and Founder, Val Miftakhov said, “Certifying and selling our 600kW electric propulsion system helps ZeroAvia expand our addressable market and increase our impact in pursuit of a clean future of flight.”
The CEO added, “With nearly 3,000 orders for our full powertrains and components, achieving a first certification will be a monumental achievement for our team and for the aviation industry, unlocking clean, efficient and affordable air transport all over the world.”
The 600kW system has been designed as part of ZeroAvia’s wider ZA600 hydrogen-electric powertrain suitable for 20-seat commercial aircraft.
In 2023, the company tested a prototype of the ZA600 engine onboard a Dornier 228 aircraft at its UK base.

One of the orders Miftakhov referenced includes American Airlines’ 2024 conditional purchase agreement for 100 ZeroAvia engines.
The US airline made its first investment in ZeroAvia in 2022 and revealed in July 2024 that it would contribute to the firm’s Series C financing effort.
