Thanks Lawrence, I use assist all the time at work and at home...I have about 6 different copies of the 22D!
The prequalified section in D1.1 has the configurations, but not the specific allowances: root opening, root gap, root face, groove angle, backing strip/ring thickness, and so on. I think I'm just going to go ahead and adopt the 22 into my QMS. The only other reference I have is a very old Lockheed martin spec that has about 1/2 the info I really need.
