gaunty,
There are 4 Australian TCDS that are applicable to Metros :
the SA226-TC is certified in normal and transport category;
SA227-AC, SA227-BC in normal and SFAR41;
SA226-T, SA227-AT, SA227-TT in normal;
SA227-CC, -DC in commuter.
Even the respective models some of them have additional specific modifications which changes the certifed category.
So you dont know really unless you can see the flight manual.
As previously stated, CAO 40.1.0 appendix 3 requires engine out training.
AIP states that simulated engine failures below 1500ft at night are not permitted.
