Mandatory References We
have built a solid
infrastructure
of
maintenance references. We’re now on the downhill side heading for the hangar. But, wait! Which parts do you consider mandatory? Go ahead, guess. (You don’t have to use the word “current.”)
I’ll quote direct from FAA Order 8620.2, Applicability
and Manufacturer’s Data:
“…However, unless any method, technique, or practice prescribed by an OEM in any of its documents is specifically mandated by a regulatory document, such as Airworthiness Directive (AD), or specific regulatory language such as that in § 43.15(b); those methods, techniques, or practices are not mandatory.”
The Order goes on to define TCDS information and notes. So to sum it up, unless your reference is in the form of specific regulatory language (FAR), an Airworthiness Directive (AD), or part of an FAA-approved airworthiness limitations section, none of our previous references are mandatory nor enforceable by the FAA.
There you have it. The proverbial “By the Book 101.” We began at the bottom and circled right back to our acceptable reference roots. It’s not rocket science. (That would be FAA Part 400 through 460.) So the next time you’re asked which book you’re following, turn around and give their chain a yank by inquiring which book they think it should be.
