Couple of problems with a "Mechanical Checklist" unless this is something you are cooking up for operation under part 91 of the Regulations. You posted in the "Majors" section, so it is assumed you are wanting to develop a Supplemental Type Certificate to add a part to a aircraft Certified under Parts 25 and 43 of the Regulations.

Assuming it is a placarded thing with a switch or a guide bar when the airplane is certified, it is part of the airplane and has to be there, in working order.

How easy is it to modify? Believe me, airlines have hundreds of guys who's entire reason for being is to argue whether a checklist should say "Set," "Verified" or "Checked." The first knee jerk reaction to any problem is to put it on a checklist, until the checklist gets so long that it becomes the problem.

The tried and true solution of a paper copy, the current revision date with the FAA's signed authorization (or equivalent electronic version) is hard to beat.

MODS: If this "Mechanical Checklist" isn't for Part 25 aircraft operating under FAR 121, can we move it to a part of APC forums most appropriate for its existence.
