One out of 313 active AD's [1], 12 with no effective dates that seems to signify a different class of AD's because their issue dates are all over the map. I'm okay with 313 patches that I apply and the computer executes it from then onwards. Above a certain limit of number of AD's that should be memorized by pilots at all times, instead of entered into maintenance tracking systems for example, I'd like to hear from pilots why safety-wise that doesn't trigger a type re-certification.

I know that is expensive and time-consuming, but I certainly don't expect for example, my most senior ops team members to recall off the top of their heads more than a handful of critical procedures to execute on-the-spot without referring to the runbooks. Why does it appear that AD's are expecting pilots to apply a seemingly unbounded number of these "patches" like computers without re-training?
