In 2011, Eurocopter launched an upgraded EC145 model, designated "EC145 T2", unveiling the new type at Heli Expo 2011. The EC145 T2 is designed to significantly increase the aircraft's performance, featuring new Arriel 2E turboshaft engines, dual-digital Full Authority Digital Engine Controls (FADEC), Eurocopter's Fenestron shrouded tail rotor design, and upgraded tail and main rotor gear boxes. Considerable differences and improvements were introduced to the cockpit and aircraft subsystems, including the adoption of increasingly digital avionics and a fully modular approach to these systems; amongst the biggest changes is a sophisticated 4-axis autopilot. In April 2014, airworthiness certification from the European Aviation Safety Agency for the EC145 T2 was received, FAA certification followed in October 2014.
