GARMIN GSA 28 AUTOPILOT SERVO INSTALLATION SERVICE BULLETIN

[cole505]

IMG_1286.heic (25.44 KB)Hi All,

Have any of you installed the new Garmin GSA 28 servo’s ?  Just got off the phone with Garmin I am doing the exchange program where they send you the new updated servos charge you $2000.00 then you return the old servos and they refund your money. I am doing the exchange on my up coming Annual in September. 

So if any of you have completed this I am hoping you share your installation experience. From what I have read it looks pretty straight forward, from what the manual says. Also Garmin informed me the the servo’s should automatically update once connected to the G3X auto pilot system.

On my recent trip to California I had the autopilot disconnect on me three times.
I think I’ll reread the bulletin and call G3X support.

Cole, where did you get the “2PG” serial numbers from? All I found were “6N” serial numbers on Garmin website. My 2018 Sling 2, has “2PG006456 & 457. Did I get lucky?

[LSA Flyer]

I'm having my P2008 done next month. I'll post my experience. The "2PG" units are part of the replacement program. Call Garmin to start the exchange when you are ready to do the swap. I got the exchange within a couple of weeks.

Hi Sling,

These were installed in my 2018 P-2008 airplane that I bought new. I am not sure I would call it lucky, but I am glad that Garmin is stepping up and replacing them 😊 I would contact Garmin and get started there are several steps that you must do to get your replacement servos. There are a few options that you can chose from. If you read my original post I go into detail about the process. Hope this helps 😊

I’m putting it on my CC and will receive a credit when my original servos are returned. I’m waiting on a callback once the RMA paperwork is completed, it should be this week. Will keep you in the loop.

Can the servo serial numbers be found in the G3X setup screens? or do you have to get the serial numbers on the servos themselves ??

You can retrieve them from configuration mode in the G3X. Make sure your avionics master, if you have one, is on. When I first booted up my G3X, I had the avionics master off and the GSA28 info was blank. Re-booted with it powered up and they pitch and roll serial numbers displayed.

Replacement Servos arrived yesterday. Will be taking the Sling in for its annual/condition inspection some time next week.

[LSA Flyer]

Completed the exchange and install. I had Sport Aviation in Little Rock do the swap since I had the P2008 in for a parachute install. Both servos are easy to access after removing the seats and access covers. It should be no more than a half day labor. Flew home for a 6 hour trip with no errors or drop outs. I also have an Astore which is much more of a PTA and requires a athletic, trim, mechanic, with small hands to wiggle in back. Since I've got 5 years to make the swap I'll hold off on that one for now since it works perfectly.

Well folks, here’s my update. Took the Sling in for its annual/condition inspection, 5 year rubber and servo swap on August 31st. Picked it up November 30th! Yes fellow flyers that’s 3 months. Had to wait for a hose and a couple of proprietery filters. Sadly, the owner lost his dad and that lost a few days, then Mother Nature and my schedule got hectic. All said and done it flys!

No issues with the inspection or the servo swap. As of yesterday Garmin received back my originals and I got a credit this morning for my $2,109.00. The 5 year rubber was completed and I took her up for 30 minutes, staying close to the field and talking to departure/approach until my return. They de-cowled, inspected the hoses, re-cowled the plane and off I went home. Pretty uneventful flight. I did have to reboot the A/P on the first flight, but the trip home it worked like a charm.

Today I went to the hanger and loaded 9.31 and updated my map database. Hopefully will fly next week.
