I would suggest that before one starts condeming Kalita and/or engine types that they do at least work with discoverable facts.
Since nobody has posted any pictures of this latest event or something other than second hand rumor that the inferences of blame are unwarranted.
And as for AD action and yet another failure.
The best the industry can do is to minimize failure conditions to an extent that it is extremely unlikely that other than average pilot skill will save an aircraft due to en engine failure.
