I have another question. I heard about the Challenger 300, a Bombardier plane that was certified in 2003, so over 15 years ago. Like the Boeing 737 MAX, it had a manual reversion mechanism in case of hydraulic loss. That aircraft was the subject of a concern paper, as you call it.
I would really like to know why such an aircraft would be approved in Canada in 2021 when it was the subject of a concern paper in 2003.
