Try the C182T manual, July 2012 amendment. Kicks in at 5 years. Absolutely ridiculous... But does not have to be a big deal if done sensibly and just means new aircraft will have been under a more rigorous maintenance regime than the 30-40 year olds flying around. Although clearly there are some pretty good 'business opportunities' for the more zealous LAMES who see a need to pull out engines, pull off wings, rip out interiors etc so that these inspections can be done properly on 500 hour, 5 year old fully corrosion protected airplanes.
Just one extreme to the other...
