My brother-in-law does fire/crop dusting with a turbine helicopter. My mentality of what an airplane annual should look like is profoundly different then what he considers 'normal maintenance' on what he uses for work. Every single part of one of those machines has a ridiculously short time to live. I've heard rumors that parts past their time to live would ship to less rigorous countries. Likely a bunch of EOL parts in the mix too.
