It gives all operators a short time to complete the installation of the FAA beta lockout system. Interesting that Transport Canada has not already required it, considering it came out in 2005.
The AD doesn't mention installation of Beta lockout, well the one I downloaded doesn't.

I had heard that Beta Lockout with a 4 month compliance was in there, but the kits have a 4 month lead time, but it doesn't seem to be mentioned.
The MEL revisions are interesting. Effectively removes Autopilot from MEL as well as actually removing RADALT and the Beta Horn.
I'm not sure what the change to the autopilot MEL has to do with in flight operation in the Beta bange.
