Pilot DAR speaks the truth:
don't want to sound unkind, but, an engine sheds a turbine wheel, and takes out both the other engine, and the flight controls for the tail as well...
However, in this respect the plane could still be certified - but only because turbine wheels are certified to be "prime reliable" and thus should never fail.
Except maybe once in a while...
And then of course there's
N60NA. Not a turbine wheel, but #3 eng. fan blades flew everywhere, including the #1 gearbox and the #2 inlet.
