Write down engine model and S/N, prop M/N, S/N, and any TSO equipment you can think of. Mag M/N, S/N, starter M/N, S/N, alternator?, ELT, ignition switch, etc. Find your engine by name or product. You'll have to look under both Lycoming and Textron. Scroll the AD's and note any that COULD apply to your engine. Then pop them open to check applicability and compliance time/method (if applicable). Do the same for prop if certified. For appliances its trickier. Try using manufacturer name, but be aware things like mags, carbs, and starters have changed owner names. You actually should check each name, ie. Slick/Unison, Marvel/Precision/Facet, Bendix/TCM, ACS/Gerdes. Big thing is engine and prop. You'll probably miss a few zingers like AD84-26-02, but I've yet to see a DAR pull that one out.
A log entry should be made for each AD that mentions your product. Entries need to contain the 5 items; date, ACtime (specify), description, signature, signers number. Examples:
1) 1/1/12, Total Time = 0.0. C/W AD84-26-02 (paper filters) by installation of new filter, P/Nxxx. Filter replacement due at 500.0 Total Time. Joe Blow xxxxxxxxx Builder.
2) 1/1/12, Total Time = 27.5 AD2-16-2012 (NOx injection) Not Applicable by S/N. Joe Blow xxxxxxxxxx (rep cert #).
3) 3/1/12 Tach Time = 420.0 C/W AD93-05-06 (ignition switches), par. a), and b) I/A/W ACS SB92-01. Next due at 920.0 Tach Time. Joe Blow xxxxxxx A&P.
You can also make or steal a list template and list your AD's in groups (Powerplant, Propeller, Appliance Repetitive) as long as it carries all 5 items.
