BEFORE TAKE-OFF: Before proceeding with a ground run-up, be sure that the propeller system is purged, by feathering the propeller once or twice with the Power Lever in the Idle Position. The following procedures should be used to check the Propeller Overspeed Governor: 1. Place the propeller lever in full increase RPM (forward) position. 2. Increase RPM with the power lever to at least 2100 RPM. 3. Momentarily exercise the prop test switch and note a small decrease in the RPM (2025 ± 20). This checks the prop overspeed governor.

ENGINE FIRE IN FLIGHT: In case of an in-flight fire, the following procedures should be used: 1. Power Lever IDLE POSITION. 2. Propeller Lever FEATHERED. 3. Fuel Condition Lever CUT OFF. 4. Fuel Aux. Pump Switch OFF 5. Fuel Valve OFF ENGINE SHUTDOWN IN FLIGHT: 1. Propeller Lever FEATHERED 2. Fuel Condition Lever CUT OFF POSITION 3. Fuel Auxiliary Pump Switch OFF 4. Fuel Valve OFF 5. Power Lever IDLE POSITION ENGINE FLAMEOUT: The indications of any engine flameout will be a drop in the interturbine temperature, torque pressure, and RPM. The flameout may result from the engine running out of fuel or possibly may be caused by unstable engine operation. Once the fuel supply has been restored to the engine or the cause of the unstable operation eliminated, the engine may be restarted in the manner described under Air Starts following: If Ng RPM Has NOT DROPPED BELOW 50%. 1. Igniter Switch - Continuous. FAA APPROVED: Oct. 24, 2006 Revision 2, SECTION III-1

25 Thrush Aircraft Inc Model S2R-T34 SECTION III EMERGENCY PROCEDURES 2. Fuel Aux. Boost Pump - ON. If Ng RPM Drops Below 50% and No Re-light is observed. Use the Following Procedure: NORMAL AIR STARTS: NOTE Air Start Envelope Normal Air Starts ranging from sea level to 12,000 feet altitude and above 80 MPH to 126 MPH indicated airspeed have been approved. The recommended pre-air start check procedure is: 1. Propeller Lever Anywhere in operating range. NOTE Propeller feathering is dependent on circumstances and is at the discretion of the pilot. Fine pitch selection will pump air through the engine, and; therefore increase the gas generator motoring speed during the Air Start procedure. 1. Power Lever IDLE. 2. Master Switch ON. 3. Fuel Valve ON. 4. Fuel Condition Lever CUT OFF. 5. Fuel Auxiliary Pump Switch ON. 6. Fuel Pressure Indicator 5 PSIG minimum. The recommended air start procedure is: 1. Starter Switch ON. The minimum gas generator RPM to obtain a satisfactory light is 12% Ng. 2. Engine Ignition Switch ON. 3. Fuel Condition Lever LOW IDLE / GROUND IDLE POSITION, after approximately five seconds of stabilized gas generator speed. NOTE A relight normally should be obtained within 10 Seconds and will be evidenced first by a rise in gas generator RPM. A rise in the interturbine temperature will also be noted. When the engine reaches idle RPM: 1. Engine Starter and Ignition Switches OFF. FAA APPROVED: Oct. 24, 2006 Revision 2, SECTION III-2

26 Thrush Aircraft Inc Model S2R-T34 SECTION III EMERGENCY PROCEDURES 2. Propeller Lever INTO OPERATING RANGE. 3. Power Lever ADJUST to desired position. 4. Fuel Condition Lever HIGH IDLE / FLIGHT IDLE. 5. CHECK that the Engine Operating Limits are not exceeded. If a satisfactory start is not obtained, discontinue the air start. Repeat the engine start procedure if another starting attempt is to be made. NOTE The best air start technique is to initiate the restart procedure immediately after a flameout occurs, if the pilot is certain that the flameout was not the result of some malfunction which might make the attempt to restart dangerous. There is always the chance that the engine may restart successfully just as soon as the ignition is turned on. In a flameout situation, move the igniter switch to the on position as quickly as possible, if the gas generator speed has not dropped below 50%. Under these circumstances it is not necessary to move the fuel lever or feather the propeller. However, the power lever should be returned to the idle position. ELECTRICAL FIRE IN FLIGHT: 1. Battery Switch and Generator Switch OFF. 2. All other Electrical Switches OFF. 3. Circuit Breakers CHECK to identify faulty circuit, if possible. If electrical power is essential for the flight, try to identify and isolate the faulty circuit by doing the following: 1. Generator Switch ON. 2. If the Generator Switch is defective, MOVE the Generator Switch to the OFF position and then MOVE the Battery Switch to the ON position. Let a short period of time elapse before activating additional circuits one at a time until the defective circuit is identified. 3. Defective Circuit OFF. EMERGENCY EGRESS: 1. Rear Occupant COMMUNICATE intentions (Dual Cockpit Only) If it is necessary to remove the cockpit door from its hinges, do the following: 2. KNOCK OUT the oval panel below the window.
