I know there was a thread on 201 cowling repair that was pretty detailed several years ago, but I’ve been unsuccessful finding it, obviously failing to limit my search (84 pages!) I guess my Boolean logic is rusty. Cowl and crack? Maybe you could school me on my search logic!

Why no TFR data message? Software, hardware or simply no TFR data being broadcast?

Kinda sad that you spend $$$ and you end up with this. And Garmin just throws it back to the installers. Sound familiar??

I have the G3X EIS and have seen the wild fluctuations ever since the installation 350 hours ago. FP at zero for minutes at a time, even at startup. Fuel flow is fine, and engine runs perfectly. We replaced sensor, installed snubber to no avail. Boost pump, switching tanks, no change. According to a company who regularly collects engine data, JPI devices will see it, but much, much less frequently than Garmin, and usually snubber fixes it for JPI. One of long-body drivers here solved a connection contamination using contact cleaner, but mine are the Garmin environmental connectors, so no joy. I have given up.

I’ve got a couple of these. One is new in box “28V” electrical system

Besides the usual 3 approaches and holding, what else do you do? Partial panel, I presume. How about sim electrical failure w/glass? (I understand Garmin has a recommended protocol for instructors which I have not seen, but do not pull CB). Comm failure: approach using a handheld. Approaches w/ iPad (never done it). Recovery from unusual attitudes. How much w/AP vs hand flying? Other ideas?

Fortunately I do not need the engine…yet; I was planning ahead. But I cannot afford more “forever” delays either. This 5-6 month push will affect 1000 customer orders, so there is some demand.

I emailed AirPower a couple days ago about the status of my rebuilt IO360, ordered in April and targeted for December 2025 delivery. Now it is May 2026! Note that AirPower was notified September 6th. And they have my deposit! Lycoming Reschedule Letter.pdf

Referencing the FP graph above, you will notice I have readings of Zero fuel pressure for several minutes.

1989 J-Model equipped with G3X with EIS. All sensors are stable, except for Fuel Pressure; check out a recent flight below, noting time scale. Equipment was installed March 2022, 350+ hours ago, and this problem has been there since Day 1. FP sensor was replaced, then a snubber installed, and fuel line to the sensor was bled. I tried turning on Fuel Pump in flight. No change when each of these changes were tried. I have literally hundreds of tracings where fluctuations occur at all phases of flight. Recently, FP showed zero on taxi to the runway, then suddenly came alive! I’ve also seen an RED “X” thru the FP gauge occasionally! Air in line is suspect, but some of the tracing shows Zero(!) fuel pressure for minutes! Cannot believe that is air, but Garmin seems to think so! I was fighting altitude oscillations until recently when G came out with alternate gain settings. Now that’s fixed, so one last gremlin! Suggestions, please. Also, I’d like to see what others are seeing with their Garmin EIS. Thank you in advance for your help. Peyton

I have one, but removed from 28V M20J. Pm me if interested.

Since 1987, I have been married to the same wonderful woman and we have owned the same house. I have owned the same Mooney since 1993. I am afraid to change anything!

AD is for runaway pitch trim. The FAA turned Gamin’s SB into an AD. It does NOT include optional gain setting to address oscillations.

I have had no other issues; guess I’ve been lucky.

Just spoke to Garmin Aviation Support. It’s a “glitch” on the Garmin Aviation Database Manager page: the G3X will not support database transfer and never will because data transfer speeds are too low, so no Synch. That’s one of the limitations of the G3X. So, 2 SD cards needed. Garmin will fix the issue.
