Or one could leave the inop ADF in the aircraft, file FPL with it in the equip list, and if someone were to come along at some period of time afterwards one could claim that ithe ADF failed after the approach was executed …

Yes Timothy, that was really what I wanted to hear with this thread. How many people are doing these NDB approaches via GPS without any ADF in the aircraft?
Loads of aircraft presumably. If you do so you are in breach of the law. Each pilot needs to decide if they are comfortable with that. The risk of prosecution is very low and the chance that an accident is caused by so doing is almost non-existent. But that doesn’t change the reality that you are supposed to have one on board.
If you make an approach in low-IFR to an airport with only an NDB approach, that is the most likely case for a ramp check to ask to see your ADF.
