For what its worth and it may be worth investing in......... Cessna do a book and for the life of me I can't remember it's name, I will look at work as I have one.......
It's something like the 100 series progressive maintenance inspection book
This is based on their experiences from higher houred aircraft and gives you additional points to look at on your aircraft, will dig it out at work and let you know the title, it lists on hours and locations specific points it thinks should be addressed like as a rough off the top of my head example...... inspect the engine bearer to firewall mount (the bearer part) at 10,000 then every 5,000 hours for cracks etc.........
will get you the details tomorrow, memory allowed for
