Ground Handling & Storage
3.1
TOWING
All Jabiru aircraft are relatively light and should always be moved by hand.
Moving the aircraft is accomplished by using the wing struts, prop hub or landing gear struts as push
points.
CAUTION
Do not use control surfaces to move the aircraft
– Damage to the control system may result
When pushing or moving the aircraft, take care that you do not jam your fingers under the rudder or
in the rudder hinge
– remember that it is connected to the Nose Wheel and will move whenever the
nose wheel direction changes.
The aircraft may also be moved by placing the propeller in the horizontal and then placing one hand
on the propeller on either side of the spinner. The aircraft can then be pulled forward.
WARNING
Never move the aircraft in this manner whilst the engine is hot as it may fire when the propeller is
moved and result in severe injury.
Always ensure that the Master and Ignitions are OFF.
Never approach the propeller when anyone is in the aircraft.
Always treat the propeller as LIVE! IT KILLS!
3.2
JACKING
Before jacking, ensure that it is as light as possible by removing luggage and any unnecessary fuel.
3.2.1 JACKING MAIN GEAR
1.
Remove main gear spat on the side to be jacked or both spats if both wheels to be jacked.
2.
Where equipped, the fuel filler cap vent of the wing which is not being jacked may be blocked
using a vent cap. This is to prevent fuel leaking onto the wing while the aircraft is jacked.
CAUTION
Where a vent cap is used ensure that it is large and highly visible to ensure it is removed on
completion of the work.
3.
The aircraft can be lifted on one side by a person of reasonable strength (or 2 of lesser strength)
by lifting on the Wing Spar
– lift at a point in line with the wing strut and about 1m (3 feet)
outboard of the strut attachment. Be careful lifting close to the wing tip as the wing structure in
this area is quite light and can easily be damaged by misplaced jacking loads.
4.
Place a solid block (preferably wood) under the bottom of the composite glass leg which will
result in the wheel being off the ground when the aircraft is lowered. Be careful not to interfere
with brake components or Wheel Spat attachments. Chock the opposite wheel.
5.
Repeat for other side if necessary.
3.2.2 JACKING NOSE GEAR
1.
Push down on Tail Plane (NOT THE ELEVATOR) until nose wheel is off the ground.
2.
Place trestle or drum under rear fuselage together with absorbent material such as foam block,
sandbags or a pillow. Alternately, a pillow or similar may be placed on the ground so that the
ventral fin rests on it when the tail is pressed down.
CAUTION
If using a trestle, ensure it does not foul Ventral Fin.
3.
Protect the paint of the horizontal tail using rags, pillows etc and weigh down tail plane with
sandbags or similar heavy absorbent material
– do not use anything hard as items like bricks are
likely to damage the aircraft) material. Place weights as close as possible to the aircraft centreline
and, where possible, apply weight symmetrically to both sides of the aircraft.
CAUTION
