Engine Failure During Take Off Run
Throttle - Idle Brakes - Apply Mixture - Cut Off Flaps - Up Ignition Switch - Off Master Switch - Off
Engine Failure Immediately After Take Off
Airspeed - 60 kts Mixture - Idle Cut-Off Fuel Shutoff Valve - Off Ignition - Off Flaps - As Required Master Switch - Off
Engine Failure In Flight-initial procedure
Airspeed - 60 kts Carb Heat - On Mixture - Full Rich Check Fuel Shutoff Valve - On Check Primer - In and Locked Ignition Switch - Both (or Start if Propeller is stopped)
Emergency Landing Procedure without engine Power
Airspeed - 60 kts (Flaps down) 65 kts (flaps up) Mixture - Cut Off Fuel Shutoff Valve - Off Ignition Switch - Off Flaps - As Required (30 deg recommended) Master Switch - Off Doors - Unlatched just before touchdown Touchdown - Slightly Tail Low Brakes - Apply Heavily
Engine Fire In Flight
Mixture - Idle Cut-Off Fuel Shutoff Valve - Off Master Switch - Off Cabin Heat and Air - Off except for wing root vents Airspeed - 85 kts or higher Execute Forced Landing Procedure
Electrical Fire In Flight
Master Switch - Off
All Other Switches - Off (except ignition)
Vent/Cabin Air/Heat - Closed
Fire Extinguisher - discharge
If Necessary to Continue Flight - Turn Electrical Switches on One by One until Faulty Circuit is Identified
Ammeter Indicates Excessive Rate of Charge
Alternator - Off
Nonessential Electrical Equip - Off
Land as soon as practical
Low Voltage Light Illuminates
Increase RPM - If Light Remains Illuminated -
Radios - Off
Master Switch - Off Then On
If Low Voltage Light does not illuminate
Radios - On
If Low Voltage Light remains on Comes Back On -
Alternator Switch - Off
Nonessential Electrical Equip - Off
Land as soon as Practical
Vacuum System Failure (Direction Indicator and Attitude Indicator Inoperative)
Rely on Electrically Powered Turn Coordinator
Carburetor Icing
Throttle - Full Open
Carburetor Heat - Full On
When Engine runs smoothly - Reduce Carburetor Heat as required (minimum amount required) - Lean Mixture if Necessary
Suspected Spark Plug Fouling
Switch Ignition - L - R - to try to verify cause of rough running engine
On ground - increase RPM 2000-2200 Lean Mixture to Recommended Lean Settings
In flight - If problem persists, determine if richer mixture results in smoother engine operation, if not, land as soon as practical
Low Oil Pressure Indication
Check Oil Temp Gauge
If Normal - proceed to nearest airport
If High - Reduce Engine Power and Prepare For Immediate Precautionary Landing
