Most engineers I know would think I'd lost the plot if I didn't do a complete pre-flight myself. Nothing to do with manuals,releases and various regulations around the world etc.
Just that any seasoned team of Engineers/Pilots would never under estimate the ability of a human being to f*** up on a regular and ongoing basis.
The old scenario of a ' wrench laying near an inlet/control run' is for real sometimes, and the bazillion minor and not so minor problems I've found doing a pre-flight, didn't become major because I found them...Then a engineer guy fixed em...
As you'd appreciate an engineer running out to stop you backing into something you didn't see, or forgot about...He/she appreciates you double checking their work.
Trust isn't anywhere in the picture....They don't want you to trust them.
They want you to double check?...
At least that's the feedback I get from some of the great ones I've worked with...
