EASA clipping CPL(A)'s wings?

[+200 No Flags]

While browsing through EASA's FCL NPA, I ran across this:

SECTION 2
Specific requirements for the aeroplane category – CPL(A)
FCL.305.A CPL(A) Privileges
in commercial air transport
(a) The holder of a CPL(A) shall only act as pilotincommand in commercial air transport on a singlepilot aeroplane provided that:

(1) When carrying passengers under VFR outside a radius of 50 NM (90 Km) from an aerodrome
of departure, he/she has a minimum of 500 hours of flight time on aeroplanes or holds a
valid instrument rating; or

(2) When operating on a multiengine type under IFR, he/she has a minimum of 700 hours of
flight time on aeroplanes, including 400 hours as pilotincommand.
These hours shall include 100 hours under IFR and 40 hours in multiengine operations. The 400 hours as pilotincommand may be substituted by hours operating as copilot
within an established multipilot crew system prescribed in the Operations Manual, on the basis of two hours of flight time as copilot for one hour of flight time as pilotincommand.

(b) The holder of a CPL(A) shall only act under IFR as a singlepilot
when he/she complies with (a)(2)

and with the applicable requirements prescribed in Subpart OPS of PartMS 2 .

(c) The holder of a CPL(A) shall only act as pilotincommand in commercial air transport in multipilot operations provided that he/she has completed the command course prescribed in Subpart OPS of PartMS 3.

I do not remember ever reading this in the JAR-FCL. Was this ever the case under JAR?

Also, does anyone know what point (b) means? Reference is made to point (a)(2), but this deals with multi-engine aircraft whereas point (b) seems more of a general IFR nature. Where can this Subpart OPS be found by the way?

Thanks.
