Single Engine IFR charter.
Further to my earlier comment Cirrus aircraft are not approved for S/E IFR charter.
As I recall three turbo prop types can be approved by the regulator for IFR charter. They are the TBM, the C208 and the PC12. All individual approvals I understand. The aspect of S/E charter also has another twist in that the piston engine must be within a 12 year limit. That means that while an aircraft engine can have say a TBO of 2000 hours it may have only reached 1000 hours by the 12 year limit. OK, the aircraft can continue to fly up to and beyond 'on condition' but only on non pax charter ops. The 12 year limit also applies to twin pistons.
Some people have been pushing for the Cirrus brand to be approved for IFR charter based on having an emergency parachute but I have not heard of a CASA approval to date.
