There may be some connection between this service alert and the misleading pitch attitude and AFCS nose down hard-over events that I experienced in phase 1 flight test. At that time Garmin and CubCrafters blamed my "events" on a defective GSU 25C and it was replaced. Earlier this week I experienced another extreme pitch attitude error. It was only when I report this to CubCrafters that I learned of the service alert.

If you fly at night, and don't have a G5 or other backup attitude indicator, you should look at this Service Alert. I can assure that, even in day VFR, an AFCS nose down hard-over will be attention getting. On a dark night with no visual reference recovery will be much more difficult.
