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 engine thoroughly.
2.
Seal or cover all openings.
3.
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.
4.
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, to inhibit corrosion. Rotate the propeller 10
– 12 times, leaving
it in the horizontal position. When all cylinders are treated leave prop horizontal and retreat
each cylinder.
NOTE: Use SHELL Aero fluid 2UN (MIL-C-6529C Type 1) or similar engine corrosion
inhibitor.
5.
Install spark plugs and connect leads.
6.
Remove the rocker covers from each cylinder head and spray corrosion inhibiting oil into
the rocker chambers and reinstall rocker covers.
7.
Seal exhaust pipes. Attach a red streamer to each.
8.
The fuel tank breather must be covered but MUST NOT be sealed
– the expansion of
gases within the tank can severely damage it if there is no escape path.
9.
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.
10.
Every 7 days the propeller should be rotated through 5 revolutions without running the
engine
– leave propeller in the horizontal position.
CAUTION
Ensure that the Master and Ignition Switches are OFF before turning motor!
7.2.4 Inspection During Storage
1.
Generally inspect engine and clean as necessary.
2.
Inspect the interior of at least one cylinder through the spark plug hole for corrosion at least
once a month.
3.
If, at the end of the 90 day period, the engine is to be continued in non-operational storage
– repeat Steps above (most will only need to be checked).
7.2.5 Returning Engine to Service After Temporary / Indefinite Storage
After temporary storage, the procedures for returning the aircraft to service are as follows:
1.
Check battery and install.
2.
Check carburettor air filter and service if necessary.
3.
Remove warning placard from instrument panel.
4.
Remove materials used to cover openings.
5.
Remove, clean and gap spark plugs.
6.
While spark plugs are removed, rotate propeller using the starter motor for several
revolutions to clear excess preservative oil from cylinders.
CAUTION
Ensure that the Master and Ignition Switches are OFF before turning motor!
7.
Install spark plugs
– torque to setting given in Table 10.
8.
Check fuel filter
– replace if necessary.
9.
If returning to service after indefinite storage, fill fuel tanks with correct grade of fuel.
10.
Check fuel tank and fuel lines for moisture and sediment. Drain enough fuel to eliminate
any moisture and sediment.
11.
Check that the fuel tank breathers are clear.
12.
Perform a thorough pre-flight inspection.
13.
Start and warm engine.
