The PT6 engine installed on the AW139 is EEC controlled.
Computer control in normal operation AUTO GOVerning mode
Manual control, thanks to an ECL (Engine Control Lever), in back-up operation MANUAL GOVerning mode.
To MEGAN and noooby, the EEC has its own hard drive called DCU (Data Collection Unit) attached to the engine.
It records all the engines cycles, fault events and exceedances.
