Not to mention - in the U.S., anyway - alternative methods of compliance,
which are FAA-approved alternatives to the original FAA-issued Airworthiness
Directive and which typically come into being when people (read: [typically]
owners, repair shops, users and others with an economic interest in the
aircraft affected) feel sufficiently strongly that they convince the FAA the
original FAA-mandated fix (AD) can be accomplished in an alternative
(typically less draconian/expensive) manner (AMOC).

Ah, perfection; thou art indeed a virtue!
