Anyone have a link to the CAA extract that discusses prosthetics certification? I'm on my phone and can only find the vision chapter. I found a summary of it elsewhere and it suggests that the prosthetic arm is "inspected" to the same standards as the aircraft only if the pilot has two prosthetic arms. If the pilot only has one prosthetic arm the pilot demonstrates that he can fly the plane without it should it fail.
I'd like to read the actual document if I can find it. I'm hoping it says engineered instead of inspected.
