FAA publishes special conditions for ZeroAvia ZA600 electric engine, advancing hydrogen‑electric certification

The FAA published special conditions for the electric‑engine component of ZeroAvia’s ZA600 hydrogen‑electric powertrain, a regulatory milestone ZeroAvia calls a “major step” toward certification. The move defines novel airworthiness requirements for the ZA600 and clears a key hurdle for hydrogen propulsion on regional aircraft.
