Hate to say it but I think CASA got this one just about right
Sage words Oracle but I ask; got it right on what evidence? Got it right for which engine ... all of them including the latest version it seems? Sorry Oracle, I disagree, casa as usual got it wrong and overreacted. A disgusting restriction on an Australian manufacturer who has succeeded despite all odds.
Given the evolution of this engine, the latest version should be exempt save for perhaps a reduction in TBO.
