CAAAD
This AD also is a follow-on to an EASA AD. To be honest, you should include the reference to possible OIL FIRE. You seem to take a rather ambiguous approach to regulations, apologizing for them? I take them at face value. They are written as a Last Ditch curative, hence the specificity of their language. Last Ditch because they are composed with the input of the Manufacturer, who generally has more knowledge and experience. (The FAA is required to ask for Public comment as well).
I read them at face value, as they are intended.
