12-10-02 Defueling
D A N G E R During the aircraft defueling observe the safety pre-
cautions specified in section "12-10-01 Refueling".
Using appropriate containers, defuel the aircraft by pumping
or by siphoning off fuel through the filler ports (only for the
wing tanks) and by opening the gascolator and center tank
drain valves.
12-10-03 Fuel Drains
The EXTRA 330LX has three fuel drain valves to provide for
drainage of moisture and sediment. Two fuel drain valves are
located under the fuselage in the area of the landing gear; the
third fuel drain which is interconnected to the fuel gascola-
tor is located in the lowest point at the right side of the
firewall.
D A N G E R Do not drain the fuel system when the engine or the
exhaust is hot or while the wind is strong.
A quantity of fuel must be drained prior to the first flight of
the day and at least five min. after refueling to inspect for
water and/or contamination. Continue draining until free of
water or contamination.
I M P O R T A N T After draining, you have to be sure that the fuel drain
valve is returned to the closed position and the valve
is not leaking outside the aircraft.
12-10-04 Replenishment of Engine Oil
The engine oil replenishment is accomplished by pouring oil
into the oil filler tube. The oil quantity can be conveniently
checked by use of the dipstick, which is attached to the oil
filler cap.
