I sincerely hope that you are merely misinformed and willing to search
for further information/education on this subject.

In another post, I have supplied MEL references for all to read.
Aside from a couple of Part 121 MELs that I have had a part in

I now await documented references from those that maintain that
the FAA has issued MELs to operators of Cessna 172 aircraft.
