So some manufacturers do report the statistics.

I didn't ask but good to know.

All I'm asking for is the type of info Trio provides above. Garmin must have at least some idea of the % of failed units.

Have you called Steve and asked him?

Call TeamX and voice your concern. They are good people!

I didn't really see the point, after he declined to state the failure rate publicly here in response to several requests. Telling me personally on the phone would be the same as posting it publicly here, because that's what I would turn around and do.

But who knows? I'll give him a call and report back.

Meanwhile, despite Garmin telling me that they wouldn't have any new servos until 5/31, they apparently hit my card and sent me one yesterday (!). So that's good news. I'm assuming they've now fixed the problem.

You may find that developing a relationship with these folks personally can lead to a much better experience.

Didn't need to do that with the guys who built my S-Tec -- but I'm certainly not opposed to the idea.

So, in an effort to learn what caused my autopilot to disconnect by itself, I came across this thread. Here's my story...

Yesterday in the final throws of my IFR checkride, during the flight portion (of course) of the test my ap disconnects. I presumed that I hit the trim buttons, so I re-engaged it. After about a couple of minutes it disengages again. This happened several more times and I was unable to complete the exam. As you can imagine, this was somewhat discouraging!

Additionally... After the incomplete exam had ended, I elected to fly the airplane to a friend's airport nearby. Upon departure, on crosswind my oil temperature red lines not once, but twice. Fuel pressure does the same thing. Clearly these were erroneous. It makes me wonder if the seperate occurances were related or not? During the balance of the flight the engine instruments were stable, but the ap kept checking out.

I called support, but this being a weekend day they won't be available until Monday morning. I would really like to know where to begin looking for my fault. I have removed the data log and was wondering if there would be a smoking gun in it?

When one experiences a bad servo, what is the failure? Could this be my problem? Are these problems even related?

I just updated my firmware to version 11.60. Is there a bug in it? Anyone else had a problem with the new firmware?

Is there a problem with another LRU?

Are these issues related in any way?

Any advice would be appreciated.

I am absolutely beside myself. This has never happened before and for it to happen during my checkride was so unlikely!

Hello CJ,

Sorry you are having trouble. The first step would be to email us the data log from your SD card for this flight which should tell us something about the reason for the autopilot disconnect.

Thanks,
Steve

Excellent!

I will send it out this morning!

Thank you for your prompt attention!

CJ

Seems strange to me that the exam would be discontinued due to an inop AP, I would have thought flying the procedure by hand and working through the problem successfully would be more important than watching the AP fly the airplane.
