Another milestone in electric motor tech for H55

H55, a pioneering leader in electric aviation, is pleased to announce a significant milestone in its pursuit of certifying its electric motor technology. The European Union Aviation Safety Agency (EASA) has agreed to H55's Compliance Check list (CCL) for its electric motor and motor controller, demonstrating the safety and performance of the entire electric propulsion management system (EPS).

This achievement follows closely on the heels of H55's previous success in gaining approval for its battery packs and energy management systems. These two significant achievements positions H55 as the first company to satisfy all certification requirements for the entire EPS which includes the motor, motor controller, battery modules and energy management systems.

These certifications are tailored for general aviation and commuter applications with the first set of systems being integrated into certified flight trainers which will soon enter the market.

Headquartered in Switzerland, H55 is at the forefront of electric aviation, specializing in electric propulsion, battery storage, and energy management solutions. With a commitment to safety, performance, and sustainability, the company is committed to enabling the aviation industry to reach et Zero emissions, offering cutting-edge technologies for a greener and more efficient future of air travel.

The newly established agreement with EASA marks another important achievement in H55's mission to revolutionize clean aviation. It is a crucial step in securing formal certification of H55's complete electric propulsion system and an important recognition by the certification authorities on the reliability and capabilities of the company's propulsion solutions.

Key Highlights of the Agreement:

Full alignment of the electric motor and motor controller Compliance Checklist with the EASA defined regulations

H55 is now fully authorized to complete the certification test program for its propulsion unit and for its overall EPS

The testing program encompasses rigorous evaluations proving the safety and performance aspects of the technology 

The CCL test program opens the door to the final regulatory approval phase

Commenting on this accomplishment H55's Co-Founder and Executive Chairman André Borschberg: "Certification has and continues to be one of the cornerstones of our strategy. This agreement represents a significant step forward on our company's development, as well as bringing electric aviation to the market and reducing the aviation industry's environmental footprint. I am especially excited about this development as we are closer to seeing the first set of certified electric airplanes soon taking to the skies."

H55's Chief Executive Officer, Martin Larose, goes on to say that "this agreement is yet another important recognition by EASA that our propulsion systems are safe and robust. This brings H55 a step closer to full commercialization of our technology which is being increasingly sought after in the market. We continue to remain appreciative for the close collaboration we have with EASA, and we look forward to our continued cooperation."

In addition to its certification activities in Europe with EASA, H55 is actively engaged with the Federal Aviation Agency (FAA) in the United States and Transport Canada in Canada. These regulatory bodies will closely follow the Compliance Check List testing program, aiming to leverage the results to expedite North American Type Certification.

H55 takes pride in being one of the first European electric aviation companies to successfully navigate this critical phase in the certification process. With agreement on the Compliance Check List, H55 advances to the final stage of securing a Type Certificate for its electric propulsion system, suitable for multiple fixed-wing general aviation and commuter aircraft.
