I'm an ex-Jabiru powered aircraft owner and have flown Jabiru powered aircraft for hundreds of hours. I was consistently impressed by the engine and was happy to cross the Channel behind it on several occasions.
I am aware that it has been developed over the years to address shortcomings, but this CASA document is going too far. Its going to be massively damaging to Jabiru and is working against them to get them to improve their prodcut rather than with them. How are they going to be able to afford the development work to eradicate the faults if they can't sell any more engines because everyone has been scared off? Don't forget that the engines they'll be selling now already incorporate many of the improvements. Its the older engines that allegedly have the design flaws.
Hopefully someone from the LAA will be along soon and provide stats for Jabiru vs Rotax 912 failures. I'll be surprised if the Jab is as bad as the nay-sayers would have it.
