Jabiru twin
It looks like the Jabiru TWIN has passed all the hoops and is now a certified aircraft in South Africa.
I understand single engine performance is as required for twins but have not seen official figures ( and that is for fixed propeller !).
Re jab engines, time to put some things to rest. The second generation ( ie the first hydraulic lifter ) had issues, oddly enough only seen in flying schools at sea level. After long investigation found due to crank case resonance from the lifters that when added to thermal cycling gave premature wear to thru bolts.
Solved in the third generation ( and also in second generation engines upgraded to third generation specs ).
The reliability of the third generation seems on a large number of hours accumulated significantly better than Rotax.
Fourth generation engines have just started production ( early 2017)
