Too late! CASA Only needs to delay and Jabiru is toast and with it any other possible Australian engine start ups.
The mere threat of rule making will destroy sales.
This of course begs the question, asked already by others, of exactly what statistical data CASA is using to justify its position. I would assume a rock solid statistical case that demonstrates beyond doubt that the Jabiru engines are unacceptably unreliable.
I assume this is based on ATSB data...."oh wait! Do they investigate Jabiru incidents?"."...or is this the same as Pel Air? Reach the conclusion then construct the data that justifies it?
