Narrative:

I was performing a 100 hour inspection which the owner wanted me to hurry up on. The owner then asked me to sign it off as an annual inspection. I very hurriedly looked up what airworthiness directives were due on it. Thinking I had found all the airworthiness directives that were both due and applicable; I complied with those airworthiness directives and signed off the aircraft as airworthy and ready for return to service. This past wkend the owner told me he discovered that I had missed a propeller airworthiness directive. Airworthiness directive 2003-12-05 mccauley propeller 1a103/tcm. I was vaguely aware of this airworthiness directive but did not believe it applied to this propeller because there is no 'B' or 'J' stamped on the propeller. Today; after very carefully rereading the airworthiness directive; I discovered that there does not have to be a 'B' or 'J' stamped on the propeller for it to be applicable.
