The last AD List I worked thru was on the '62 C-172 which we acquired to train a family member. That airplane has so much in common with 170's that it might be of interest in this thread. Notice that a lot of AD's are applicable to accessories that may not at first grab your attention...but are nonetheless of importance to 170 owners. The Brackett Air Filter AD (96-09-06, Checks the gasket integrity and is N/A if the later frame has a "lip" to prevent gasket slippage)... although now long-past history, is an example of an AD that should still be included in the list and signed-off as Complied or Not-Applicable...whichever applies. Just because it was signed off ten years ago... does not mean that someone didn't buy a filter assy from a salvage yard and install it when no one was checking old AD's, for example. (It's a Catch-22 example for parts bought from salvage.)
Anyway, it takes time to run an AD list and keep it updated each year, ... an oft-forgotten/dis-respected task of an IA that sometimes surprises owners when they get this years Annual Insp/Invoice that needs to pay the IA for his time. An owner can sometimes save real money if the owner keeps the AD list updated for the IA's Annual Insp, ... and it's always seen by a new inspector as evidence of an owner's diligence toward maintenance....(can help keep the costs down.)
It's always a good idea to print-out a copy of each AD and keep in the records for review and to support any past sign-offs. (The one applicable to AmeriKing ELTs (2017-16-01) was not previously reviewed by the former owner...is an example found during the prebuy/annual. In-fact, the ELT installation did not even meet the Mfr's or FAA installation instructions as it did not include a required cockpit-remote RCPI. When I located the installing AP/IA he had little recollection of his installation 20 years ago. Finding the obsolete part and correcting the installation became one of the challenges of the pre-buy/annual, ...otherwise a new ELT was in order.)

Here's the one used on the 172 which may be helpful (be sure to add 96-09-06 added after this file was created):
Now... if you go to the FAA website linked above... and if you search for ADs applicable to "Cessna 170"... you will find NONE LISTED. This is because the FAA website now recognizes that Cessna's Type Certificate is now owned by TEXTRON. You must search for TEXTRON 170.
Here's the listing that is returned:

Notice that not even the FAA website listing of potentially-applicable ADs is not complete. One needs to also consider added equipment and STCs and ohter modifications made to YOUR airframe/engine/propeller/avionic/etc and research each of those appliances. (They miss the ELT AD note, for example among many others.)
Hope this helps.
