Hello folks, I’d like to get your advice and opinion on this. My aircraft is G1000 equipped, with a GRS77 Garmin AHRS. A few months ago, I lost artificial horizon and heading on firm (not hard) touch down. I checked the connectors to both PFD and MFD, and also to GRS77. No bent pin, no free movement, no dust or corrosion preventing contact. I used KONTAKT 60 cleaner. The thing didn’t appear...
