Look at the "
Easy Access Rules for Air Operations"
Under Annex IV (Part-CAT), Subpart C, Aircraft Performance and Operating Limitations (Helicopters), Chapter 4: Performance Class 3
CAT.POL.H.400
(d) Operations shall not be conducted:(1) out of sight of the surface;
(2) at night;
(3) when the ceiling is less than 600 ft; or
(4) when the visibility is less than 800 m.
Considering all single engines are PC3 by definition, this prevents them from being used for commercial air transport operations under IFR.
