Section 8 – Aircraft Care and Maintenance
4. MAINTENANCE
4.1. REFUELLING
- Do not perform aircraft refuelling near flames, sparks or similar.
- Avoid fuel contact with the skin: a skin corrosion could occur.
- Make sure that a fire extinguisher is available nearby during refuel-
ling operations.
- Make sure that overall aircraft instrumentation is turned OFF before
performing the refuelling.
- Do not operate switches and/or pushbuttons inside the aircraft during
refuelling operation; make sure that crew left the aircraft before
performing refuelling.
- Make sure that the aircraft is electrically connected to the ground.
4.2. OIL LEVEL CONTROL
1. Open the inspection cap on the engine nacelle
2. Prior to oil check, switch off both ignitions circuits and turn the propeller
by hand in direction of engine rotation several times to pump oil from the
engine into the oil tank, or let the engine idle for 1 minute. This process
is finished when air is returning back to the oil tank and can be noticed by
a murmur from the open oil tank.
3. Clean the dipstick and soak it in the reservoir
4. Remove dipstick and read oil level
5. If required, replenish oil: oil level should be between max. and min. mark
of the oil level dipstick
1. Close the inspection cap
2. Repeat the procedure for the other engine
