Even if you would fund the STC, getting the parts you need to retrofit the pressurization system with an “G1000 independent version” could be a significant challenge. You might either depend on salvage parts from older Malibus or have to do quite significant engineering to design some new parts.

Agree to this: Haven’t heard of a Malibu that ran out of airframe life limit yet – neither of a crash that was caused by a structural failure of the airframe based on aging.

AFAICT it is purely to do with getting a more recent aircraft.
If you convert say a 2001 airframe, you are still getting a plane which is 20 years old, and that’s before you started flying it. My plane is 19 years old now and while it is in a very good condition, it has over 2000hrs on it.
And a PA46 is not a 10hr/year plane. I reckon most airframes will be high-hour ones. And pressurisation cycling can’t be helping much, too.
I don’t know why anyone would want a G1000 system over G500/G600TXi and a GFC500/600 with GTN.
I’d love to read a Jet Prop POH sometime.

Yes, I think I might have to join up the MMopa to get the manuals. That link is one to buy the manuals, maybe the owner’s group would be a good investment first. I know a guy who has the 1988 model converted with the -21 engine. Looking at some of the material online it seems like the older airframes with the -21 engine could be the best value buy, but not necessarily the highest performance. The one I got the flight in was a 1999 model with a -34 engine which was superb.
OK so no actual legal reason why a G1000 PA46 cannot be converted. Just nobody wants to fund the STC, and a 2008 airframe is plenty recent enough to be acceptable.
I’d love to read a Jet Prop POH sometime. If anyone has a soft copy it would be great to read that. The Jet Prop is the dream.

I’m pretty sure that the TXI (at least currently) does not support cabin pressure control.
No. And that’s not Garmin’s development strategy – they don’t want to develop G1000 NXi replacement with TXi; they want to address avionics retrofit market leaving as many as possible airframe specific things “as is”.

I’d assume it is almost impossible and surely economically unattractive to retrofit an “analog style” cabin pressurization system into a G1000 Malibu – both from legal (STC) as well as from practical POV.
I’m pretty sure you’re right. G1000 and airframe marriage is for life, sealed with TC.
