I can't believe there are people here that think these SID's aren't mandatory. They aren't an SB they are a directive and form part of the maintenance manaul. They are a manual revision. Therefore, if you maintain your aircraft as per the maintenance manual, the SID's are mandatory.
I don't see how you can get around that? I'd love to hear how these aren't mandatory?
As for the 'a good engineer will have been doing this stuff and it won't be a problem'.
I don't know too many engineers that have been removing wing struts to do eddy current inspections on bolts holes just to name 1 page of 200 in the 100 series SID's.
Any engineer worth his salt will have to think long and hard before he/she shrugs off this new manual revision during your next annual/100 hourly.
