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.
4.2.2.2 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
Do not lift using control surfaces. Damage to the control surface or control system may result.
4.
Place a padded trestle or similar under the front of the fuselage immediately aft of the cowl outlet
to ensure that the nose cannot drop down if the aircraft balance is disturbed.
4.2.3 Hoisting
This procedure should not be necessary for most service or maintenance procedures. Should
hoisting be necessary:
1.
Drain Fuel from both wings (Wet Wing models only) & Remove wings.
2.
Fit shackles to wing support brackets (4 off).
3.
Fit cables/rope to shackles and to a centre lift shackle.
4.
Hoist only from this point ensuring that cables/ropes do not mark the top of the fuselage at
corners above wing support brackets.
Refer to sections below for details on procedures for fuel draining, wing removal etc.
4.2.4 Levelling
Longitudinal Levelling:
For longitudinal levelling use a spirit level on the lower door sills, or
For longitudinal levelling use a spirit level on the trim decal on the centre console.
Lateral Levelling:
Apply a spirit level to the flap drive cross shaft, or
Apply a spirit level across the aircraft, referencing the join line of the cowl top & bottom halves.
4.2.5 Parking
It is strongly recommended that aircraft are stored in hangars wherever possible to minimise
degradation caused by the elements and pests.
Parking precautions depend principally on local conditions. As a general precaution, check the
wheels and tie the control handle back firmly with a seat belt to lock the controls. Park into the wind
and tie down the aircraft as outlined in below if a hangar is not available.
