# Which FAA or EASA regulation does prevent a high wing to cross the passenger compartment?

I'm looking for reference subpart and eventually chapter in either FAA or EASA regulation where it is stated that for passenger aircraft with high wing passenger compartment can not be interrupted by fuselage-passing wing, so the wing must be placed above the fuselage (with additional fairing thus increasing drag and weight - eg. ATR-42).

I know this is quite obvious but I need a regulation reference for a report.
