I'm looking for some help/advice.
I am the owner of a Robin ATL, small single engine light aircraft, which is (under)powered by a JPX 4T60 engine (basically a VW aero derivative engine). There is an alternative version flying with a Limbach engine, but both are slightly under powered.
So I was thinking about replacing the old JPX, when it's due for replacement, with perhaps a Rotax, or other such equivilant. On the face of it, the Rotax is about 19 kg's lighter than the JPX, so there are no significant changes in the CG.
The plane is a French registered aircraft, so I am not sure how easy/difficult the French would be in allowing such a change. Mind you, if you believed that another CAA authority might be more open minded, let me know...but I suspect that this might be something driven by EASA.
Anyway, is it within a plane owners rights to change one certified engine out with another, or am I limited to overhauling my JPX/replacing with an already approved Limbach variant?
Any help or advice you could give me would be most welcome.
Thanks
