STORAGE
3.7.1 FLYABLE STORAGE
Flyable storage is defined as a maximum of 30 days non-operational storage.
Ensure that the engine has been stopped by turning off the fuel valve, thereby not leaving any fuel in
the carburettor bowl.
Every 7th day the propeller should be rotated through 5 revolutions, without running the engine.
Leave the propeller in the horizontal position to ensure even distribution of liquids in the wood. If left
in the vertical position, liquids will drain to the lower tip resulting in an unbalanced propeller.
CAUTION
Ensure that the Master and Ignition Switches are OFF before turning motor!
WARNING
Do not store MOGAS or fuels containing alcohol for longer than 30 days in a Jabiru aircraft. Refer
to Service Letter JSL007 for details.
Store under cover, away from direct sunlight.
In addition to the normal parking covers detailed in Section 3.5, openings in the engine cowl and
other similar openings should have protective covers fitted to prevent entry of foreign materials and
pests (especially wasps).
3.7.2 RETURNING AIRCRAFT TO SERVICE
After flyable storage, returning the aircraft to service is accomplished by performing a thorough pre-
flight inspection. Ensure all protective covers are removed.
3.7.3 TEMPORARY OR INDEFINITE STORAGE
Temporary storage is defined as aircraft in non-operational status for a maximum of 90 days.
Treat as for flyable storage (see Paragraph 3.1.7), plus:
-
For temporary storage, fill fuel tank with AVGAS (to prevent moisture accumulation).
-
For indefinite storage, drain fuel tank, ensure carburettor bowl is empty by running engine with
fuel valve off until it stops or by draining bowl.
CAUTION
Do not store MOGAS or fuels containing alcohol for longer than 30 days in a Jabiru aircraft. Refer
to Service Letter JSL007 for details.
Then:
1.
Clean aircraft thoroughly.
2.
Clean any dirt, oil or grease from tyres and coat tyres with a tyre preservative. Cover tyres to
protect against dirt and oil.
3.
Either block up undercarriage/fuselage to relieve pressure on tyres or rotate wheels every 30
days to prevent flat spotting the tyres.
4.
Seal or cover all openings. Note that wing tank breather covers MUST BE LOOSE!
5.
Remove battery and store in a cool dry place. Service the battery periodically and charge as
required.
NOTE: It is recommended that batteries not being used should be charged every 30 days.
6.
Disconnect spark plug leads and remove spark plugs from each cylinder. Using an oil can or
spray atomiser, spray preservative oil through a spark plug hole of each cylinder with the piston
in the down position. Rotate the propeller 10
– 12 times, leaving it in the horizontal position.
NOTE: Use SHELL Aero fluid 2UN (MIL-C-6529C Type 1) or similar engine corrosion inhibitor.
7.
Install spark plugs and connect leads.
8.
Seal exhaust pipes. Attach a red streamer to each.
9.
Cover but DO NOT seal fuel tank breathers
– breather covers must be a loose fit to prevent the
possibility of pressure-related damage to the fuel tanks.
10.
Place protective covers over pitot tube, static source vents, air vents and openings in engine cowl
to prevent the entry of foreign material or pests (especially wasps).
11.
Attach a warning placard to the instrument panel stating that vents and breathers have been
sealed and that the engine must not be started with the seals in place.
