Does not sound like that in this case. If, as they say, it was human error and a valve problem, what they mean is, the person in charge of setting the cable properly did not do so.
There is a person(s) below deck that are told the type of aircraft coming in to land, who then set the cable tension/response for that aircraft. Each plane has a different setting. The person below deck got the wrong aircraft info or had the right aircraft but set the cable improperly.
The “buck” stops with the command. Why do we shield this en competence? it is going to end abruptly
