Grumman,

There may be some rules of thumb out there. Most of these rules are ways to avoid detailed structural analysis. I would expect this to not be avoided in aviation.

Is it possible and practical to turn that nut? This is an assembly quality issue, although that cotter pin will keep it assembled.

The two holes are close together. Can you do a stress analysis on that part between the holes?

What is the problem? The fasteners are on different surfaces.

Why don’t you ask the aircraft manufacturer? Any company standard is PROPRIETARY and should not be posted publically.
