The SID(s) to which you refer don't exist yet. The Skymaster Owners and Pilots Association just submitted a 38 page brief to the FAA, addressing every point in detail...but no documents will be forthcoming from the FAA until next year.
You can get a copy of the SOAPA's statement by emailing
[email protected] , and Larry Bowdish will forward the 38 page report.
The idea behind an AAIP is that you write it. You can do just about anything you want, so long as all the necessary mx and inspections are done.
If you have an existing program and additional inspections become necessary, then you can always revise.
So far as what's mandatory and what's not...many manufacturers will attempt to create "mandatory" SB's and mandatory inspections. Until they petition the FAA to make it a regulatory requirement as an Airworthy Directive...they can call it "mandatory" all they like and it isn't. Simply because the manufacturer states it's "mandatory" doesn't make it so.
Many "mandatory" SB's and inspections are the manufacturers way of trying to protect themselves with some liability insulation. The FAA's position is that the manufacturer must submit documentation to the FAA for approval, and in the case of a manufacturer adding requirements after documentation has been approved, it's not mandatory unless they're willing to seek an AD.
The manufacturer in turn is seldom willing to seek an AD because that can have a negative impact on sales, as well as hurt the reputation of the manufacturer.
You've got a ways to go before you need to submit an AAIP, if you're just to the compliance statement.
