EASA has accepted H55’s battery pack compliance check list (CCL), an “important milestone” that allows H55 to finalise completion of its test programme.

A successful conclusion of the programme will see the completion of all certification requirements for propulsion battery packs for CS 23 fixed-wing applications by the end of 2024. The agreement with EASA is “the last key milestone” in the certification of H55’s battery technology, said the firm. It also forms a “critical step” towards formal certification of H55’s electric propulsion system.

Martin Larose CEO of H55 said: “This agreement is a recognition by EASA that our battery packs are safe and robust. It is also an acknowledgment to all the hard work being done by a highly skilled and competent team in demonstrating dependability and performance of our battery technology. 

Highlights include:

  • Full alignment on the Energy Storage System (battery packs and energy management)
  • Compliance Check List (CCL)
  • H55 is now able to complete the certification test programme for its Energy Storage System
  • The testing programme encompasses rigorous evaluations proving the safety and performance aspects of the technology
  • The CCL test programme opens the door to the final regulatory approval phase.

“H55 is fortunate and appreciates the close collaboration we have with EASA. We look forward to their continued support as we move into the final phases of certification as well as working together in the future as H55 unveils new products and solutions,” added Larose.

In parallel to its certification efforts in Europe, H55 is also moving ahead on its north American certification with the FAA in the US and in Canada with Transport Canada. Both regulatory bodies will be closely following the CCL testing programme with the objective of using the results from EASA to fast-track north American Type Certification, said H55.

André Borschberg co-founder and executive chairman of H55 said: “The pivotal role that certification plays in our company’s strategic vision. This advancement brings H55 closer to the ultimate goal of certification. With clear rules of compliance in place, we can now complete our testing. This significant milestone will accelerate the commercialisation of H55’s battery packs for electric propulsion solutions.”
