In the US, to be a standard maintenance procedure it better be in the
current maintenance manual. Short of that, it needs to be in a,
Service Bulletin, Advisory Directive or some type of written process
from the manufacture in order to be acceptable to the FAA. Performing
any maintenance without something acceptable to the FAA and you are
setting yourself up for loss of license and possible legal liability.

That is unfortunately is what is starting to happen here. In the past when
one signed on one's licence you took the responsibility for what you did.
Nowadays when one signs on a company approval as you say if it is not in
the book somewhere it can't be done. I guess with old fashioned machines
that was not a problem but now they are too complicated for one person to
use his judgement :-)
I'm talking about machines where the M&O manual was less an inch thick as
opposed to some today where they take up six feet of shelf space!
