H55 has taken two significant steps toward bringing its all-electric Bristell B23 Energic trainer to market, announcing a propulsion partnership with Safran and the delivery of certification-ready battery modules to BRM Aero.
The Swiss electric aviation specialist confirmed it has selected Safran Electrical & Power’s ENGINeUS motor for the aircraft, combining what the companies describe as two of the most advanced certified elements in light electric propulsion: H55’s energy storage system and Safran’s EASA-certified motor.
The agreement is aimed squarely at accelerating certification of electric propulsion systems for CS-23/Part 23 aircraft, a key bottleneck in the sector. By pairing proven components, the partners believe they can shorten the path to approval for two- to six-seat aircraft.

In parallel, H55 has delivered its first conforming, certifiable battery modules to BRM Aero, enabling the next phase of integration and aircraft-level validation for the B23 Energic.
The aircraft is being positioned as a practical solution for flight schools, targeting the fast-growing electric training market where lower operating costs and zero-emission capability are key drivers. Orders in both Europe and the US have already secured initial production capacity, with entry into service planned from 2027.
“Flight schools from Europe to North America already build their fleets around the Bristell B23, a platform certified under both EASA and FAA and available across several engine configurations,” said Martin Bristela, CEO and co-founder of BRM Aero.
“Adding certified electric propulsion from H55 and Safran to this foundation means operators can transition to zero-emission training with minimal disruption. Same cockpit, same support network, new powertrain. That is a practical path to electric flight.”
