Sorry, just going off on a slight tangent here.
Do you think that part of the problem is that most pilots aren't given a maintenance component in their training, and consequently are fiddling with stuff they don't know about, and haven't had thou shalt not touch and the reasons why (eg invalidate insurance etc) drummed into them?
There is a list of stuff pilots can and can't do in the regs, but even with the short list there are some things that can be royally screwed up if not done in the right way. But I have yet to find anyone who actually has a maintenance component worked into their flight training program. Or do maintenance guys think it's better that pilots don't look under the hood at all?
