Single engine light aeroplane on the Nanaimo airfield Vancouver Island BC Canada. SCO
The propulsion system consists of a single fuselage mounted Pratt and Whitney PT6A-140 turboprop engine. The PT6A-140 is rated to 867 shp at 1900 rpm. Time between overhaul for this engine is 3600 hours. Conventional turboprop controls are used to operate the engine and propeller. They consist of a power lever, emergency power lever, propeller control lever and a fuel condition lever. The power and fuel condition levers are engine controls while the propeller control lever controls propeller speed. An emergency power lever is provided to manually control fuel supply to the engine should a malfunction occur in the fuel control unit. Engine operation is monitored by the engine indication system (EIS) which shows numeric readouts of critical engine, fuel and electrical indications for the following: torque, propeller speed, interstage temperature (ITT), gas generator % RPM (Ng), fuel flow, oil pressure and oil temperature. A wet type standby engine torque gauge is also installed. Engine torque is limited by a sen- sor that reduces fuel flow if an over torque occurs.
