The fairings include panels for maintenance access to some parts of the aforementioned systems. Some panels which are likely to be opened frequently are hinged at the front, and have quick-release fasteners at the back. These are never as large as 4' X 8'. Removable panels of that size are secured by many fasteners, which in my experience are usually of the Dzus type, or similar, necessitating the use of a screwdriver (sometimes with a proprietary head).
Not necessarily.
B777 Air Con access panel is hinged and is substantially bigger than 8' x 4'.
It ain't hinged at the front neither.
