Reading the comments from France above, and in other Forums, there seems to be a problem with Jab Engines going "bang", and a slowness or inability to correct the problem(s).
While I do not want to get into a Ford-Holden type argument between Jab-Rotax, I just wonder how many more Jab engines would be sold if their reliability was improved.
Where I got my pilots certificate they had both Jab and Rotax powered trainers. As I wanted to get my own aircraft I asked questions regarding the respective engines. The answer was along the lines of all Jab's they had owned had major problems,while the Rotax's had not.
I got a Rotax powered aircraft after stopping an order for a 230 following a couple of 160's I knew had major engine problems on quite newish engines.
Personally I think Jad's are the best value for money aircraft in Australia and generally like the way they handle having flown three different types, HOWEVER I will be very reluctent to ever purchase one until their engines show a better history of reliability.
Wounder how many people do not purchase, or will not repurchase, Jab powered aircraft due to engine reliability?
