I hate to interrupt the pizzing match of Levy and Downey (and to be honest, I can't see Tom's remarks since he's on my blocked list) but actually in this instance a owner can sign off this AD on a routine oil change. He just has to be careful in the way he signs it off and make a reference to sign it off as "AD 80-04-03 R2, para B".
An owner is allowed by regulations to change the oil and "Cleaning or replacing fuel and
oil strainers or
filter elements". The inspection of visible particles in the oil doesn't require anything special.
I've come across several AD's during my time that could be logged and signed off by the owner operator.
And Ron, you play this silly game every time you get backed into a corner.
