An Envoy Canadair CRJ-700 (N520DC) was en route at FL360 about 10nm south of Syracuse, NY when the crew decided to divert to Syracuse reporting a problem with the FADEC on the right-hand engine (CF34), the engine was reduced to idle thrust but was kept running. The crew requested emergency services on standby, requested a number of delay vectors to prepare the aircraft and passengers for landing and landed safely on Syracuse’s runway 10 about 25 minutes after leaving FL360.
A full authority digital engine (or electronics) control (FADEC) is a system consisting of a digital computer, called an “electronic engine controller” (EEC) or “engine control unit” (ECU), and its related accessories that control all aspects of aircraft engine performance. FADECs have been produced for both piston engines and jet engines.
The aircraft remained on the ground for about 2 hours, then was able to depart again and reached Chicago with a delay of about 2:15 hours.
