I didn't see it listed on this AD, but it sounds similar to one that a friend just addressed on his late model (2001) 304 CZ-17. He originally thought the AD was overkill, especially for something as new and well-taken care of as his, but when they got into performing the actions to comply, found very significant levels of corrosion and was happy they had discovered it.

He monitors this forum, so perhaps will chime in and relate his thoughts and experiences on this subject.
