I agree with Nooby, once you get an AME licence you are out of the system and left to your own devices (unless youre in a 145 organisation) . If your procedures drift off from the Rules or the MM its left to your peers to point it out.

I will always believe it is another way to reduce the minimum requirements for aircraft maintenance and supports a lot of operators who shouldnt be in business in the first place.
There should be one standard for helicopter maintenance.
