Regarding the "signing off the missing static wick so we can fly to an mx base to get it fixed" example, forgive me for my ignorance of part 121 maintenance practices but... couldn't they just get a ferry permit from the FAA?
Don't know how it is at other airlines, a missing static wick is not an MEL it's a CDL and pilots cannot flight crew placard a CDL. A mechanic has to sign off a CDL.
Until a few years ago, pilots at Eagle couldn't do flight crew placards even though flight crew placarding was a normal thing at other regional airlines.
Even if it's going to a ferry a mechanic has to sign off a ferry permit.
