I've noticed one or two planes at my airport continuously park on the Taxiway and stay for sometimes an hour+. I keep looking and can't seem to find any regulations on this topic. (Only finding stuff about taxiway construction) Can someone find me something released by the FAA regarding this issue. Are they to be fined or just told "move it".
If it's an airport with a Control Tower, access to the taxiway is controlled by ATC.
If it is an airport without a control tower, then concerns about aircraft parking on a taxiway would probably best be addressed with the entity that owns the airport (City, County, State, Port Authority, etc.).
The airport manager would likely be a good initial point of contact to whom you could voice your concerns.
Under the conditions and circumstances specified in 14 CFR 91.13 (b), that regulation may apply.
14 CFR 91.13 (b) states:
(b) Aircraft operations other than for the purpose of air navigation. No person may operate an aircraft, other than for the purpose of air navigation, on any part of the surface of an airport used by aircraft for air commerce (including areas used by those aircraft for receiving or discharging persons or cargo), in a careless or reckless manner so as to endanger the life or property of another.
