It's interesting to note the strong criticism of Jabiru coming from people who appear to happily roar around in their 2 stroke Rotax powered aircraft. I have experienced several engine failures with these power plants (Pegasus Q trike Rotax 462, Avid Flyer Rotax 582 and a Lightwing Rotax 582 - seized). I have also flown around Australia in a Jabiru SP6 in company with two other Jabirus and apart from some ice induced rough running, no problems. I've now had two aircraft with Jabiru engines - no issues so far. It's true that you shouldn't stake your life on any mechanical device but we do. What we powered aircraft owner/operators need to do is be diligent when it comes to the operation and maintenance of ANY brand of aircraft engine. Arm ourselves with as much knowledge pertaining to the engine/aircraft we operate.
