Additional
Preflight inspection
In addition to the Pre-flight inspection described in the POH – Section 4, the following must be done:
•
Remove all snow from the airplane surfaces, and remove any icing using hot air
•
Check the control surfaces for free movement. Check the slots of the control surfaces and
flaps. Remove any snow or ice
•
Check the fuel tank vent hose for openness before each flight
•
Check fuel system (fuel filter) for debris, if found, empty the fuel tank and refill with fresh fuel
•
Check fuel for water prior filling (use of water separator/filter is recommended)
•
Drain fuel tank (drain valves are located on the bottom side of the each wing), drain a small
quantity of fuel; check for water and other contaminates until fuel is clean and clear.
1.6.6.4.
Pre Heating Engine and Oil
It is permissible to start an engine without pre-heating if the outside air temperature is not below +5
°C. Pre-heat the engine and oil if air temperature falls below 41°F (+5 °C). Use suitable air heater or a dryer.
NEVER USE OPEN FIRE TO PRE-HEAT AN ENGINE!
Blow hot air from the front into the hole around the prop (engine covered with fiberglass cowlings).
The temperature of the hot air should not exceed 212°F (100°C) at air heater output. Warm up the oil
tank along with the oil in the engine. Pre-heat until cylinder head and oil temperatures exceed 68°F (+20° C).
1.6.6.5.
