CD-300 on Long-body Mooney?

[Boilermonkey]

Diamond is putting the CD-300 on their newest airplane.  It makes me wonder if it could be put on a long-body Mooney.  Having just put a reman TIO-540 on our M20M $$$$, I wonder what it would take to put this engine on?   It’s about 50 pounds heavier, different prop, mounts, would require a rework of the fuel system for Jet-A, FADEC/instrumentation.    

As a one-off I know there would never be a payback, but over several aircraft what would the lower cost of the engine, maintenance, fuel burn, etc. be?

Maybe make the converted aircraft “experimental” and get less expensive avionics too?

Unfortunately, this is not really a viable option for something useful for travel. Otherwise we’d all be flying “experimental” Mooneys.

You would need an STC, one time or a full STC. It can be done, but it will be a lot of work.

NOPE, should def go on a short body first, specifically a 1974 m20e

You might run a new weight and balance with +50 lbs on the nose and see if your plane is still flyable, or able to carry people in front.

I'm sure the FAA will allow you to make your Mooney experimental while you are working on the STC. And they will allow it to be certified after the STC is approved. 

So, what would the engine swap cost?

Engine                                                 $100K

Prop & spinner                                    $10K

Engine mount, engineering and DER  $20K

Cowl, engineering and DER                 $50K

Misc. systems engineering DER           $25K

Test flying and taking data                  $20K

Creating POH supplement                   $5K

Preparing STC paperwork                    $5K

Total                                                     $235K

 

I'm probably leaving out a bunch of stuff, but this is probably in the ballpark.

+1 for serious WnB calculation….

 

BM,

Also know the current IO550 is pretty far forwards from the firewall for some reason….  You might have a few extra inches to work with that you might not have expected…

How much HP does this engine provide?

Best regards,
