After already having accepted its compliance check list for its battery Packs and energy management systems, the European Union Aviation Safety Agency has now approved H55’s Compliance Check List for its electric propulsion motor and motor controller.

This achievement follows H55’s previous success in gaining approval for its battery packs and energy management systems. H55 believes it is 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 specializes in electric propulsion, battery storage, and energy management solutions.

Key highlights of the agreement include 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; and the CCL test program opens the door to the final regulatory approval phase.

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.

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.
