Any FAA or other regulations prohibiting taxiing between parked aircraft? So the other day I was getting checked out at a local FBO, after returning to the ramp, instructor told me to taxi between two parked (tied-down aircraft). It was a tight squeeze but I taxied at about 1 MPH and I looked at left wing while instructor kept an eye on right wing. I really didn't think anything of it. Note, access to the other side of the line was blocked off by some vehicles so we couldn't taxi in from the back, hence cutting between two parked aircraft. However, we could have shut down on the front and pushed the aircraft back into its parking spot. 

However, about 5 minutes later, a car drove up to us as we were securing the aircraft. It was the owner of one of the aircraft that we taxied next to. He spoke to the instructor, I didn't hear exactly what he said, but it was something about not taxing so close to his aircraft. Personally, I have no problem, pushing the airplane back into its spot, but it got me thinking about what regulation if any is implicated here.

I looked, and didn't find anything. So my question is whether there are any FAA, airport or other regulations or rules that prevent a small aircraft from taxiing between two parked aircraft on the ramp? I don't think there is any legal authority prohibiting taxiing between aircraft, or how many feet you must keep from a parked aircraft. 

This reminds me of the aviation joke:

Aircraft Squawk - Left main almost needs to be replaced.

A&amp;P Response - Almost replaced left main. 

In this case:

Aircraft owner - You almost hit my airplane.

Me - You're welcome.
There isn't any such regulation.  That part of the airport is a "non movement area" (if you want a reference).  Of course, you want to be a good neighbor, and not toss rocks, etc.  I usually push my airplane into parking, and pull it out before engine start.  But that is just me.
