Preflight Check
The preflight check includes removing tie downs and chocks, ensuring control locks and covers are stowed, and checking the avionics are off. The pilot must verify fuel quantity, check external electrical switches, and inspect the aircraft's exterior for damage. Specific checks for the wings, undercarriage, and engine compartment are detailed, including checking oil levels and ensuring all surfaces are clear of ice or snow.
Starting the Engine
The checklist outlines procedures for cold starts, hot starts, and starting when flooded. It emphasizes the importance of throttle and mixture settings, as well as the need for a clear area before engaging the starter. Specific RPM settings are provided for starting and after the engine is running.
Takeoff and Landing Procedures
The takeoff section includes vital actions such as setting the trimmers, mixture, and fuel pump, as well as ensuring the flaps are set as required. The landing checklist emphasizes securing hatches and harnesses, checking fuel levels, and ensuring the carburettor heat is on before landing.
Emergency Procedures
Emergency procedures cover engine fire during startup, power loss during takeoff, and in-flight engine power loss. Each scenario includes steps for maintaining control, checking fuel selectors, and preparing for a power-off landing. The checklist also addresses electrical fires and oil pressure loss, providing clear actions for pilots to follow.
Safety notes
- Aerobatics and spinning prohibited
- Ensure oil pressure rises to green arc within 30 seconds after start
- If engine fails to start, do not engage starter for more than 10 seconds continuously

ENGINE POWER LOSS DURING TAKE OFF If sufficient runway remains for a normal landing, land straight ahead If insufficient runway remains: Maintain safe airspeed by lowering the nose.

MASTER SWITCH OFF / FUEL OFF /MAYDAY IF TIME PERMITS ENGINE POWER LOSS IN FLIGHT Individual circumstances will vary but generally below 2,500 ft. AGL GoFly recommends the following;_ Turn Down -wind (increases your glide range). Establish a glide attitude and trim. Select a field towards the wing-tip if possible –left or right. Plan the pattern of your approach using “constant aspect” technique. Then check for cause of power loss if this is not obvious. Fuel Selector……………………………………………..………………….….……Switch fuel tanks.

When power is restored: Carburettor heat………………………………………………………………………………….….…..OFF Electric fuel pump…………………………………………………………………………………..……OFF If power is not restored prepare for power off landing. MAYDAY call and set 7700 unless already allocated a squawk. Touchdowns should normally be made at lowest possible airspeed with full flaps.

LOSS OF OIL PRESSURE Check oil temp. gauge. If remaining normal suspect pressure gauge failure. Land as soon as possible and investigate cause. Prepare for POWER OFF LANDING. HIGH OIL TEMPERATURE Check Oil Pressure. If low/zero prepare for POWER OFF LANDING. If Oil Pressure is normal:- Reduce power and richen mixture. Increase airspeed if in the climb. Land at nearest airport and investigate the problem. Prepare for POWER OFF LANDING ALTERNATOR FAILURE ALT annunciator light illuminated / low voltage light flashing.

If circuit breaker normal:- ALT switch……………………………………………………………………………………………………OFF After 5 seconds ALT switch……………………………………………………………….………………………..ON AGAIN If power not restored: ALT switch…………………………………………………………………………………………………. OFF Electrical loads…………………………………………………..Reduce to minimum essential Land as soon as practicable. Battery is the only remaining source of power. Advise nearest Air Traffic Unit or 121.50. Anticipate complete electrical failure. Be aware that radio transmission makes a heavy drain on battery. Reference to the circuit breakers will give an indication of individual current loads. RADIO FAILURE Radio……………………...………………………………….Check frequency, volume, squelch, switches, ( individual and Radio Master) Headset…………………………………………………Check plugs secure, change headsets, Check ammeter, master switch, circuit breakers – reset once only Transponder………………………………………………………………............................Set 7600 Speechless/transmit blind/non-radio procedure as appropriate
