WARNING
12-10-02 Defueling
Before you defuel the aircraft, make sure that it is electrically grounded. Incorrectly
grounded aircrafts can cause accidents.
Also obey the safety precautions in chapter 12-10-01.
To defuel the tanks, use containers with applicable dimensions. Use pumps or siphons to
remove the fuel from the tanks through the filler ports. Open all drain valves. Refer to
chapter 12-10-03.
12-10-03 Fuel Drainage
The aircraft has three drain valves:
The drain valve of the main tank is on the bottom side of the fuselage in front of the main
spar.
The drain valves of the wing tanks are on the bottom side of the wing.
Do not drain fuel while the engine or exhaust system is hot or in strong winds to prevent
accidents.
When the fuel is drained, close the drain valve correctly and make sure that there are no
leaks.
To drain the fuel:
1
Before you drain the fuel and examine the fuel drain valves, wait for a minimum of 5
minutes after refuelling. Thus, moisture and sediment can collect at the bottom of
the tank.
2
Use a transparent container to drain a quantity of fuel before the first flight of the
day.
3
Let the drained fuel collect at the bottom of the container before you examine the
fuel.
4
Continue to drain each drain valve until there is no water and/or contamination.
12-10-04 Replenishment of Engine Oil
Refer to chapter 12-10-08 for the quantity of engine oil and the specifications.
Refer to the newest revision of Lycoming Service Instruction No.1014.
To examine the oil quantity:
1
Stop the engine and wait for a minimum of 5 minutes.
2
Open the hatch in the upper cowling half.
3
Remove the oil filler cap and the dipstick of the engine.
4
Remove the oil from the dipstick with a clean cloth or a paper towel.
5
Put the dipstick back into the filler port and tighten it with your hand.
