BEFORE STARTING ENGINE
1. Preflight Inspection — COMPLETE
2. Passenger Briefing — COMPLETE
3. Seats and Seat Belts — ADJUST and LOCK Ensure inertia reel locking.
4. Brakes — TEST and SET
5. Circuit Breakers — CHECK IN
6. Electrical Equipment — OFF
NOTE: the avionics master switch must be off during engine start to prevent
possible damage to avionics.
7. Avionics Master Switch — OFF
8. Fuel Selector Valve — BOTH
9. Fuel Shutoff Valve — ON (push full in)
10. Avionics Circuit Breakers — CHECK IN
STARTING ENGINE (WITH BATTERY)
1. Throttle — OPEN 1/4 INCH
2. Mixture — IDLE CUTOFF
3. Propeller Area — CLEAR
4. Master Switch — ON
5. Flashing Beacon — ON
NOTE: If engine is warm, omit priming procedure of steps 6, 7, and 8 below.
6. Auxiliary Fuel Pump Switch — ON
7. Mixture — SET to FULL RICH (full forward) until stable fuel flow is indicated
(usually 3 to 5 seconds), then set to IDLE CUTOFF (full aft) position.
8. Auxiliary Fuel Pump — OFF
9. Ignition Switch — START (release when engine starts)
10. Mixture — ADVANCE smoothly to RICH when engine starts.
NOTE: If engine floods (engine has been primed too much), turn off auxiliary fuel pump, set mixture to idle cutoff, open throttle 1/2 to full, and motor (crank) engine. When engine starts, set mixture to full rich and close throttle promptly.
11. Oil Pressure — CHECK
12. Navigation Lights — ON as required
13. Electrical System – CHECK FOR PROPER OPERATION:
a. Master Switch — OFF
b. Taxi and Landing Light Switches – ON (provides an initial electrical load on the system).
c. Engine RPM — REDUCE to idle (Minimum alternator output occurs at idle)
d. Master Switch — ON (taxi and landing lights on)
NOTE: (The ammeter should indicate in the negative direction, showing that the alternator output is below the load requirements, but the battery is supplying current to the system.)
e. Engine RPM — INCREASE to approximately 1500 RPM (as engine RPM increases,
alternator output should increase to meet the system load requirements)
f. Ammeter and Low Voltage Annunciator – CHECK (the ammeter should indicate in the positive direction, showing that the alternator is supplying current and the Low Voltage Annunciator (VOLTS) should not be lighted)
NOTE: If the indications, as noted in Step“d”and Step“f“, are not observed, the electrical system is not functioning properly. Corrective maintenance must be performed to provide for proper electrical system operation before flight.
14. Avionics Master Switch — ON
15. Radios — ON
16. Flaps — RETRACT
17. Mixture — LEAN for ground operations.
