Flight Idle,
Again that can be a dodgy course, say you think it is overtightened and XYZ chief tells you ignore the book and XYZ is wrong, you are carrying the can for your actions in not following the laid down procedures. I know, it seems wrong, but thats how it is, also look at the other thing, if the aircraft is needed how long does it take to pass this up the chain and assuming it does not get stopped on route, to get a reply from the manufacturer and a response back down that chain.
Civi Wise I can contact my Manufacturers rep who will contact the Company design team and I can have an answer emailed to me in a couple of days.
Though sadly the CAA of late have allowed parts of the maintainence manuals to be ignored, that in my eyes is a disaster waiting to happen, as a piecemeal approach leaves what to do and what to ignore up to the individual as opposed to you having to follow it all.
