This is an extension of the UH-1 Drag Brace topic, but it seems appropriate to start a new thread about it.
In the other thread there was talk of ICC requirements and "company critical task lists", etc. GrayHorizons is right when he says that human factors are complex when it comes to maintenance slips. In my mind no amount of regulation or company policy will substitute for an experienced, conscientious professional pilot/mechanic team.
I want to point out that this is not mechanic bashing. Pilots should be judged just as critically. To me, it is about confidence. Here is what I mean:
As mechanics, you have to fly occasionally (test flights, rotor smoothing, etc). When you get in with a new pilot, in the back of your mind you wonder if you should trust this guy. But you have no choice so you go. As you work with him he either gains your confidence or he becomes the pilot that nobody wants to fly with. Most of the time that confidence is a gut feeling (unless he does something blatantly stupid.) You make your judgements about this new pilot by watching how he handles himself. Does he walk around the aircraft before he gets in? (No legal requirement for that.) Does he yank it off the pad or is he smooth and deliberate? These observations will build or destroy the confidence that you have in a pilot. A worthy pilot recognizes that at that moment he is responsible for the safety of his mechanic.
Pilots judge mechanics in the same way: Does he keep his tools neat or does he have to root through a pile of parts from three different aircraft to find what he's looking for? Is he methodical and confident in how he works or does his mind seem to be all over the place? Does he tell the pilot that everything is ready to go or does he say "I worked on this, this and this. Look them over and you're ready to go"? A worthy mechanic recognizes that at that moment he is responsible for safety of his pilot.
There is no room for pilot/mechanic rivalry and blame. Mistakes will be made on both sides from time to time because we are human. We need to work through that as professionals without blaming and finger pointing. Pilots and mechanics have very different jobs but each is required to earn the respect (and trust) of the other.
