I believe an Icarus SAM (no longer made, but many are being removed as G5’s and such are installed), or a GDC31 can be installed to provide the switch between heading and GPSS to your 400B.

In addition to salvage yards/eBay, check McFarlane. I know I got an email recently that they now had PMA on wheel pant mounting plates that at least cover some of the years of 152 & 172s.

Your best bet on a repair for the century is Autopilots Central in OK.

The GFC500 is available for your airframe, but nothing from your century is reusable. The hardware is $6995 for the 2 axis AP, adding ~$1600 per servo for either auto-trim, or yaw damp (or both). You’ll also have to have at least one G5 installed if you don’t already. Als…[Read more]

Well, the 430 non-W 28v support ending is somewhat true, in that they will no longer repair it as a non-w, they will still upgrade it to a w and provide support however. It’s a $4400 upgrade/repair through (but it does come back essentially brand new).

I’d look at a GNC255 and GTR225 if you could swing it. I wouldn’t install a SL30 in a brand new panel like this, great radios, but pretty old at this point and who knows what the long term support will be.  Another option would be something like the trig tx56 navcom with a ty96 com. Those are a little less than the garmin equivalents.

The post by Trek is old, IIRC there originally only was the Yaw offset, but the calibration capability was added later. It’s called out in section 7.2.5 of the Garmin GTX 3XX STC install manual and demonstrated in the video posted above.

The AHRS in the GTX 345 isn’t great, I’ve heard a lot of complaints about it. The best thing would be to take it to your dealer and have them level the aircraft and then run the calibration on the 345. You can do the calibration through the configuration mode (while you have the aircraft leveled per MM) if you are so inclined, but make sure you…[Read more]

I just removed an ARC 400B and  installed a dual G5/GFC-500 (3 servo, no yaw) in a friends T210N. It really flies the plane well, I’m pretty impressed with it. I have a S-tec 3100 (upgraded from a 55X) in my T210L that I also like, but for the money (especially if you don’t already have something to upgrade) the GFC-500 is a great AP.

Glad to hear you finally got it fixed! Enjoy the flying.

On a 1981, you likely already have the brackets and such built in to the airframe… just don’t have the belts. But I believe this service bulletin covers it either way:

https://support.cessna.com/custsupt/contacts/pubs/ourpdf.pdf?as_id=22176

182 has struts, the 177 and other than the really early 210’s are all cantilevered. So the structures and loads are quite different.

If I recall properly from the course, Paul recommends removing the foam to prevent corrosion to the bottom of the carrythrough. He had a particularly nasty example In his shop that had to be replaced.

I’m a big fan of Aircraft Magneto Service (https://www.aircraftmagnetoservice.net), but they are not in the Eastern half (Missoula, MT). They do great work for a good price though.

This one is on facebook: https://www.facebook.com/marketplace/item/2272869939431453/ Looks to be quite the project 🙂

They do need to be match drilled. There are often slight variations from airplane to airplane as to where the rivnuts are, so match drilling allows for a much better fit. A strap duplicator works well for this, or you can take a screw of the proper size, grind the head down to a sharp point, and screw it in to the rivnut and press the fairing in…[Read more]

Thanks Ed, couldn’t remember which year went from the regulator w/OV to ACU.

Out of curiosity, do you have to cycle the breaker (as in does cycling the alternator side of the split master not work?) Also, what’s your S/N?

Is your field breaker tripping, or are you just using that to cycle things? Do you have the Zeftronics with the built in over voltage protection, or the separate over voltage sensor (or if you installed the one with overvoltage protection, did you remove the original over voltage protection). If the field breaker is not tripping, but you cannot…[Read more]

10″ is tight, but it fits 🙂

Is it 28V only? Garmin has indicated that they are not supporting any of the 28V only 430 or 530, only upgrading them to WAAS.  I wouldn’t really wager a guess as to how much longer they’ll support the non-waas 14/28V units. I have to image their parts supply is dwindling down. They are getting some parts from their trade-up programs and from the…[Read more]
