Before commencing flight duties the responsible pilot has to carry out a visual inspection of the S10 in the
following order:
Firstly switch off ignition and main switch.
Engine:
• remove cowling
• check oil contents (min: lower mark, max.: upper mark);
on flights in excess of 8 hours: at least middle position.
• visual inspection of the engine; foreign objects in cooling air intakes?
• Inspection of all fuel lines of engine and wing connection area for leakage. The check shall be performed
with fuel pressure. For the test switch ON Master switch (with Ignition switch OFF, landing gear DOWN),
electrical fuel pump (RH fuel tank) ON, Check with fuel cocks LH and RH tanks OPEN and CLOSED.

Caution: For complete drainage of the tanks the aircraft must be kept level for a few hours before and
during the drainage.
Check that drainers close properly again and do not leak. If they leak there is a possibility of dirt
in the fuel.

fire risk does not exist.
