DC-3 piston to turbo prop mod

[repulo]

Hallo Gentlemen,

does anyone of you have an idea, how much the engineering of the piston to turbo prop STC cost on the DC-3?
I am not looking for an accurate figure, just a rough idea.

Thank you guys for your reply.

The STCs of DC3s with turboprop engines goes back over 50 years...
I recall DC3s with RR Dart turbines, BEA, in the late 1950s...
The US STCs with PT6... the Turbo-3 and many others... Jack Conroy...
Long research subject...

Thank you BelArgUSA,

I know its hard to find exact figures. To be honest, the reason I am trying to find out is, that we are considering a similar conversion of another type and before going deeply into it, we thought of getting some rough values this way.

Have you tried asking Basler Turbo Conversions in Oshkosh, WI?

fernytickles,

no I did not try them. I mentioned the DC-3 since the plane we consider converting (Albatros) is relatively similar in size and I am just trying to figure out how much the STC would cost roughly. Thanks anyway.

Try FRAKES conversions in the USA, they do the conversion for the Grumann Mallard
