The one caveat I can think of is if you use a certified engine to get the 25
hour fly off time vice 40 hour time I think you'd probably be held to the
AD.

Maybe this topic has been brought up here before, But do
homebuilt/experimental aircraft have to comply with Airworthiness
Directives set forth by the FAA? specifically, I have a lycoming O-290G
model engine in my airplane and since that engine was not designed for
aircraft use, I wonder If I have to comply with AD's on it. Also, other
accessories and/or avionics in my plane are not TSO'd so therefore I guess
there would not be any AD's on those either.

Its all a little confusing to me. Maybe someone can provide a quick answer
that makes it clear.

No certification, no ADs. Short and clear enough?
