Quite: from my post #16: Old fart here recalling his early days and a quaint Air Registration Board (predecessor to CAA) regulation that splitting or installation of any primary control MUST be signed off with a duplicate inspection by another licensed engineer. This long-retired pilot and LAE thinks that a "rudder will no longer respond to pilot pedal inputs" would have terrified him. He certainly would not have flown with it.
Glad to see someone else raising this basic regulation (not a rule).
Exam answer from memory of 60 yrs ago: What is a duplicate inspection? Answer: A duplicate inspection is first made by a licensed engineer or qualified person and certified, and then made by a second licensed engineer and again certified. Basically it meant two heads on the block if something went wrong.
