The video has been out for a while that shows the visual inspection, and the .pdf has the inspection detailed.
http://www.cessna.com/NewReleases/FeaturedNews/NewReleaseNumber-1192421847028.htmlI performed all the items at the last annual on my 57 182. It wasn't difficult, but I do have an inspection camera that helped.
I did send out my engine mount when I had the engine out for major just before this, and there was one minor fatigue crack found in the lower mount and was repired with an enhanced brace. I have 0 corrosion in the airframe, and just under 3400 hours, so it can happen, and I'm glad I took the time to inspect.
Took about 3 hours to do the whole thing, but I'm sure it will vary depending on the mechanic doing the work.
Hope this helps.
