12.10.3.26.2. Disconnect the air supply line to the speed sensitive valve (see Figure
12.8) at the bottom of the filter element installed in the line and install a #6 plug in
the open line. WARNING: Install only the AN806S6 plug stock number
4730007629456. Using improper plug may result in a bleed air leak and engine power
loss.
12.10.3.26.3. Disconnect the torquemeter shroud anti-icing at the left side of the
balance line fitting and secure it.
12.10.3.26.4. Disconnect the line from the top side of the speed sensitive valve and
connect it to the balancing line fitting where the torquemeter shroud anti-icing was
connected.
12.10.3.26.5. Secure any loose hardware then close and secure engine cowling.
NOTE: Do not start the affected engine first. Select another engine for the first
engine to be started in order to supply bleed air to the affected engine.
12.10.3.26.6. Place the Engine Inlet Duct Anti-icing switch for the affected engine to
ON.
12.10.3.26.7. Start the affected engine while watching RPM and stand by to activate
the Prop and Engine Anti-icing Master Switch.
12.10.3.26.8. At 94% engine RPM, place the Prop and Engine Anti-icing Master
switch to MANUAL. The acceleration bleed valves should close at this time.
WARNING: When the Prop and Engine Anti-icing Master switch is selected to the
MANUAL position, the engine anti-ice and prop anti-ice/de-ice systems will be
actuated if their respective switches are turned on. These switches are normally
turned on during the Before Takeoff Checklist but should be delayed using this
procedure unless absolutely necessary for safe operation. Turning these switches to
the ON position with the Prop and Engine Anti-icing Master switch selected to
MANUAL will activate the systems and rob the engines of torque. Overheating of
the blade/spinner anti-ice/de-ice systems will occur if the aircraft remains on the
ground for longer than the two cycle operating limit. NOTE: In this configuration
the affected engine will have continuous anti-icing and an associated reduction in
torque will be noted.
12.10.3.26.9. After landing, shutdown the engine in NORMAL GROUND IDLE.
CAUTION: Do not use ―LOW SPEED GROUND IDLE‖ during ground operations.
To do so may cause the engine to stall/over temperature.
12.10.3.27. Failed Fuel Shutoff Valve on Fuel Control
12.10.3.27.1. Open lower left side cowling on affected engine.
12.10.3.27.2. Remove the defective fuel control shutoff actuator (Geneva lock) from
the fuel control (see Figure 2.8).
12.10.3.27.3. Insert a small common screwdriver into the spline end of the fuel
control and rotate in a counterclockwise direction until the fuel control opens. There
will be no fuel leakage from where the actuator was removed.
