7. Aircraft Ground Handling and Servicing
7.1 Servicing fuel, oil, coolant
7.1.1 Servicing fuel
1. Verify the main switch OFF position
2. Verify that the doors are closed
3. Remove fuel tank cap
4. Service with fuel of proper type until level rises to the filler
openings (or any required level)
5. Replace fuel cap and check for security
6. wash any spilled fuel from wings with a clean water
7. repeat for opposite fuel tank.
It is not advisable to change the used type of gasoline during engine
operation. Refuelling should be carried out in places not endangering either
the aircraft, its attendance or environment. Prior to refuelling it is always
necessary to check gasoline for absence of water. Sampling should be
done both from the transportation containers and from tanks and aircraft
fuel system through drain sump. When refuelling from a barrel, a funnel
must be used provided with a strainer to trap impurities, or, even better,
with a buckskin leather which can trap also eventual fuel moisture content.
Fuel dumping is performed similarly as sampling by means of a drain cock.
When filling fuel into tanks, be careful to avoid staining of cockpit window
panels and glass with fuel as it contains corrosive components that will
cause a fast deterioration and damage to cockpit glazing. Make sure that
fuel tanks are closed when refuelling is finished.
7.1.2 Servicing oil
The proper oil type should be used
– see this manual or engine manual.
1. Make sure that ignition and master switch are off
2. Remove the top engine cowling.
3. Open the oil tank.
4. When a level is not between minimum and maximum marks (or
not high enough for expected longer operation), add oil. Do not
add oil above the MAX level
– the oil will be overflowed out of the
engine anyway.
5. replace oil tank cap
