Anyone know what is required to have Cobram go through it so someone could install it in say a M20F?

I have heard this before and I think its a few grand for the recertification of the parts. Then you have to purchase an STC and an install kit for a few grand more. So, almost the same price as a new unit. Call them to find out. Plan on a full overhaul of everything. Some BT pilots have sent a servo in for a 1500$ overhaul, it didnt work right on install, and then when they sent it in, got stuck for another full servo overhaul.

Just found this post on an earlier sale someone else had for an stec here at mooney space.

Still best to call cobham and confirm , mine only has a few hours on it so its still all looking and and working like new last week and i do not believe it needs re certified if it comes directly of an airworthy aircraft and on to another, but if it is taken off and put on the shelf and used at a later date It would require a re cert. ( check with you local faa on that ) but I just did some work up in Canada and the rules there are for the most part the same as ours and that's exactly what we learned the wording was ,

I just sold the S-Tec. Thought I would just confirm what I learned and what was mentioned above. If the aircraft the S-Tec is going to be installed in to is listed on the original STC, it only requires a new Documentation Package from Cobham for $1,450.00.

This S-Tec came out of my M20F and the guy that picked this one up is putting it into an M20J, which is listed on the STC, so he pays $1,450.00 to Cobham and he is good to go.

If the aircraft was not on the Original STC, any servo or computer that had a serial number that differs from what is required for the new aircraft, would require sending those components to Cobham for reconfiguring that could total upto $3,500.00.

Thanks for everyones input on this thread.

Sold it, stc transfer was $1400.

Good to know, thanks for following-up. That is a high cost for simply transferring parts, but better than it used to be from what I've heard.

Some BT pilots have sent a servo in for a 1500$ overhaul, it didnt work right on install, and then when they sent it in, got stuck for another full servo overhaul.

This sort of what happened to me. I have an intermittent problem with my pitch servo. After trading out the altitude transducer, the conclusion was that the problem must be the computer that controls the servo. So I said, fine, send it out to Cobram for a rebuild. Well, a few weeks later and about $850 later, I get the computer back and was of the belief that it had been reconditioned. We installed it and it worked great for about two flights... then it died altogether.

So the shop contacted Cobram to alert them that we were sending it back for a warranty claim and they then told us that they didn't actually do anything to my unit except bench test it. So, remember when I said it was an intermittent problem? Well I guess when they had it, it worked perfectly for the 10 minutes they probably spent on it, then sent it back to me with a bill, unchanged. It went back a second time and has been now repaired supposedly. Don't know if I owe any money or not. I haven't had it installed yet because my plane is sick and stuck in Red Bluff right now, but that's another sad story.
