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.
12.
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!
4.3.4 Inspection During Storage
1.
Generally inspect airframe 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 aircraft is to be continued in non-operational storage
–
repeat Steps 1-13 above (most will only need to be checked).
4.3.5 Returning Aircraft To Service
After temporary storage, the procedures for returning the aircraft to service are as follows:
1.
Remove aircraft from blocks and check tyres for proper inflation.
2.
Check battery and install.
3.
Check carburettor air filter and service if necessary.
4.
Remove warning placard from propeller.
5.
Remove materials used to cover openings.
6.
Remove, clean and gap spark plugs.
7.
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!
8.
Install spark plugs
– torque to 11 nm (8 ft/lbs).
9.
Check fuel filter
– replace if necessary.
