Meanwhile, while all you lot are reinventing the lean of peak argument, CASA has taken upon itself the role of judge, jury and executioner once again with no concrete evidence of anything at all except a feeling in its water that Jabiru engines are somehow so "unsafe" that their use, sale and production must be stopped immediately, for make no mistake, that is the likely outcome.
Furthermore, they are trying to set a precedent that would allow them to repeat this action anytime and anywhere they like with zero accountability. At least the SAAA has picked up on this precedent setting danger.
What CASA is doing is retreating from the standard of evidence based regulation in favour of voodoo economics.
To put that another way, you don't get to say "your engine is unsafe". Exactly which model and mod status is unsafe? What are the failure modes and why? Where is the statistical evidence that proves each of these hypothesis? What has the manufacturer proposed to remedy the proven defects? Is their proposal adequate or not? If not, why?
CASA's blanket ukase has to be stopped or it will be used again and again on engines and ultimately aircraft.
To put that yet another way, don't Vans aircraft have a rotten safety record? Aren't they extremely unforgiving in case of an engine failure? If Jabirus can be banned, why not Vans aircraft?
Having said all that, it appears Jabiru brought this on itself and I have no love for either it or CASA, but I'll be buggered if Rotax and all the others are going to get tarred with the same brush!!
