I've talked to multiple DERs who have adamantly held that rivets responsible for holding nutplates in place DON'T qualify as fasteners (their only job is to hold the nutplate against torqueing during assembly), therefore standard edge distance requirements (say, 2*D in the AC 43.13 or the Bell SRM) don't apply. It's accepted as common wisdom among engineers around here, and the logic makes sense.
However, I can't find a single document or manual that spells this out. As is custom in aviation, everything we do must be backed up. Can anyone out there show me where it's written that nutplate rivets are exceptions to edge distance rules? Or, if this isn't true, can anyone show me where it's spelled out that the opposite is true?
TL;DR Does 2D edge distance apply to the rivets on nutplates?
Thanks in advance for your help!
