LANCECASPER

Umm I think @Danb is in Delaware. Were you thinking of Dan Bass @DanM20C in Winona, MN?

It probably means that close to Sun N Fun or Oshkosh we'll hear about a Garmin GCO14 Carbon Monoxide Detector.

What year is your J? Are you sure you have vacuum speed brakes and not electric?

You won’t find any M20Ks with bladders. The STC on bladders does not cover anything newer than a J model. Going forward, after a reseal in Minnesota or Florida, a lot has to do with how the Mooney is maintained. If the tanks are kept low on fuel the sealant will dry out faster. If the airplane is kept outside in extreme temperatures the sealant will not last as long. If it is kept low on fuel and outside, that’s even worse. If the shock discs, the only shock absorption on a Mooney, aren’t changed when they should be they become hard and don’t absorb any shock, which is tough on aging sealant in the seams.

If you want to buy one you'll need to specify whether you need a 14v or 28v model.

And yet another airplane overshoots the very short runway at Twin Oaks in San Antonio: https://www.mysanantonio.com/news/local/article/plane-crash-san-antonio-19458224.php

Check and see - if they will, that should help a lot.

How no one got killed or seriously injured in that is amazing - during the collision or during the confrontation after. . .lol.

I don't believe it will give you altitude pre-select. https://static.garmin.com/pumac/gi275_autopilot_compatibility_c.pdf (By the way I was thinking you had a KFC150. If it's a KAP150, then the attitude indicator is a KG258, instead of a KI256. The only difference in the two autopilots is that the KFC150 has a Flight Director and the KAP150 doesn't. Everything else I mentioned applies though.) https://www.bendixking.com/content/dam/bendixking/en/documents/downloads/006-08377-0001_1-kap-150-ki-525a-pilot-s-guide.pdf

Even if that did work, you'd have to leave the Master On to do that.

I would want to have, in my scan, an AI that's failing and tumbling in IMC while my autopilot is following it.

Two G5s won't provide attitude to your KFC150 autopilot. As @Rmnpilot mentions, you'll need a GI-275 with the autopilot interface to replace the KI-256 attitude indicator and another GI-275 to replace the KI-525 HSI. This will not only allow you to remove the vacuum pump(s) but will allow you to remove the remote gyro (KG102A) in the back of the airplane. If you have an early M20M with vacuum speed brakes you'll need the vacuum pump to run them.

I had a 172RG for a year, over 30 years ago, and I always thought the gear swing looked like a giraffe getting up from a long nap.

There's Stupid and then there's Really Stupid. Stupid was to not land on the grass or a taxiway. Really Stupid was to post your video on YouTube.
