Agree, mostly.
It's not a first in the world of aviation that a product suffers because of a sub-contractor.
Lycoming crankshafts come to mind, entire fleets grounded.
AvioNG on the Eclipse jet, 50% certified for use.
And Thielert was supposed to get the engines certified for 2000hrs at some point, they just didn't manage it prior to the collapse.
But new engines were prorated if you reached 1000hrs, as in you only pay half the normal price.
So whether you run 2000 hrs and full price or 1000hrs and half price is 6 of one and half a dozen of the other.
Anyways let's hope that the Austro will turn out to be the magic bullet to really get the DA 42 going.
