Fresh CEO reporting puts Eve’s schedule back in focus. Earlier flight-test evidence shows the propulsion integration work that must support certification.
December 2028 — company certification target 27 knots — stabilized speed in August partial-transition test 1,200 rpm — pusher activation in that test
Transition testing must establish how lift propulsion, forward thrust and flight controls work together as the wing takes more load.
Higher-speed envelope expansion, conforming test aircraft and regulator-accepted compliance evidence.
Eve chief executive Johann Bordais told Axios that the Eve 100 is targeting certification by December 2028, in reporting published on 14 October.
The date is a company objective. A schedule statement does not establish that the aircraft has completed its compliance campaign, or that an authority has committed to issuing an approval on that timetable.
Eve’s 3 August release provides a documented technical reference point. The company reported a partial transition flight in which its engineering prototype activated the rear pusher propeller in the air. It listed a stabilized speed of 27 knots and pusher operation up to 1,200 rpm. These are manufacturer-reported results from August, rather than new October flight measurements.
The flight marked the start of the transition phase. Eve said further loads and structural analysis would support envelope expansion, with datalink testing intended to support operations at speeds up to 50 knots.
PropulsionWatch analysis: activating the pusher demonstrates one integration step. Higher-speed testing must establish the changing aerodynamic loads and control response as forward thrust builds and the wing carries more of the aircraft’s weight. The useful evidence includes repeatable behavior through this regime and the aircraft’s response when a propulsion or control channel fails.
Development flights inform that work. Certification additionally requires the agreed compliance demonstrations and authority acceptance. Readers should track the transition-test envelope and the conforming-aircraft campaign alongside the stated target.
