AD's

There are probably different ways of complying with the AD requirement. My A&P took exception to the historical entries that just said "All AD's complied with" and left it at that. My A&P printed out a list similar to yours, but then signed off on each one and noted if it was "complied with" or "reoccurring". Those pages went into a binder that stays with the log books. His annual log book entry makes reference to that binder, rather than listing them in the log book every AD every year. Now I essentially have four log books: airframe, engine, propeller, AD's

I went through the AD list at Univair mentioned by Ronald. I made a list of all those that applied (or arguably might apply) to my aircraft. The "comply once and done" were all noted too... even though they were complied with years ago.

I made a list that fits on a full-page printable sticker that I can print out and cut down to logbook-page size. Some are complied and done, some are "check every year" and some are "check every X years" so I have little blank lines to note when each is due, or initial if it's being done that year. This makes things easy for me and for my mechanic, and puts all the AD worries in one place in case I ever have to find it... just look for the latest annual in the logbook!

These were the stickers from my first annual. Exmple only... your plane may vary!
 
 

The FAA still has a search function

drs.faa.gov/browse/ADFRAWD/doctypeDetails

You can search with the model 415C or with Univair then the model number. You also need to be aware of ADs for all other components and accessories, i.e. engine, prop, magnetos, ignition switch, etc.

This might be your best list.

Once upon a time, the FAA had a searchable database by make and model, but it appears that no longer exists.

Is there a published list of all the AD's on the 1946-C coop?
