    Product Group: Engines (ME)

    Problem: In our G280 aircraft our crews have been reporting a cyan ENGINE SYNC FAIL cas message during climb out on most, but not all, of their flight legs. They are seeing it during climb out between 10K and 18K in altitude and only lasting anywhere from 1 to several minutes before going out on its own. We have had them try in auto and have had them select N1 and N2 before takeoff and still receiving the message. They have also noticed when the message is on that all engine indications seem to be normal nothing out of the ordinary.
