Is there a place for piston twins?

Here is the link for the Centurion Diesel Engine: I don’t know if it is suitable also for PA31 and certified by EASA.

Have a look http://www.centurion-engines.com/

In the web page, they are advertising it for EUR 64’800 as selling price.
But that it's just for the engine, nothing else. Then, to replace a old Continental or Lycoming they will charge you for the all necessary modifications as per as the engine mounts, engine system, fuel tanks and fuel system, and so and so. At the time that we have enquired for our T206 they asked EUR 115’000!!! Also they weren’t able to refund the old engine core which was USD 11’000.

Regarding to the single turboprop operation, I didn’t know that JAA were that strictly.

Yeah… you are right that PC 12 is so expensive, also a Caravan (USD 1,9 million). I do not have experience in Europe (I am working in Africa ) but let me tell you that the profit for a turboprop plane is more than double at the end. What about the Caravan II (C406)? You can get a nice one for less than a million dollars and it’s fast.

When we talk about aged planes as PA31 or Cessna 402/404/421, we never know where we are going to, what the maintenance will cost… TBO… calendar over haul and bla bla bla.

However, good luck.
