You betcha. This whole 406 ELT inspection issue has been a nightmare since they first came out. I don't think I have ever heard anybody talk about this subject at an IA seminar. IMO the FAA needs to update 91.207 so we don't need to guess or go searching for this info.

I would show the AIM reference to your DAR if there are any questions. If he has further questions he should take it up the FAA. In all reality DARs are authorized to perform airworthiness certification of aircraft, that's all. He really can't deny you the C of A based on future maintenance and inspection requirements. If you have installed a new, approved ELT in an acceptable manner (including the registration with NOAA) that is all a DAR can ask for. If he wants to do a self test performed that would be OK.
