so Rainboe, i ask you a simple yes or no question.
have you ever knowingly flown an aircraft with a no go item after considering it an non safety issue??
you are the only person who seems to have an agenda here.
engineers have only 1 goal in mind and that is to release an aircraft in a servicable condition.
whether the engineer signs for a daily check or an engine replacement for us it is the same... the aircraft is only released when we are sure that the work is performed correctly and aircraft fit to fly.
i congratulate you that you are able to perform a walk around check... well done. so here you go ,there is a spoiler mixer, can you please change it, rig the cables, test it and release the aircraft to service???
i get the feeling the answer is NO
