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.
3.3
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.
3.4
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.
3.5
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.
Whenever the aircraft is not active or being maintained it is strongly recommended that the following
points are covered to prevent contamination and pest ingress:
-
Pitot tube
-
Static vent
-
Engine air inlet
-
Exhaust outlet
-
Fuel tank vent(s)
WARNING
Ensure that fuel tank vent covers are not tight-fitting. A tight cap can prevent fuel vapours
escaping, pressurising the tank and severely damaging the tank and wings (for wing tanks).
CAUTION
Equip all covers with tags or other high-visibility devices to minimise the chance of inadvertent
operation with covers still fitted.
3.6
TIE DOWN
When tying the aircraft down in the open, head into the wind if possible. Secure control surfaces by
tying the control handle back firmly with the seat belts.
Then:
1.
Tie ropes to the top end of each wing strut or to the strut tie-down lug (if equipped). Secure
opposite end of the ropes to ground anchors located at approximately 30 degrees to the vertical,
outboard of the top wing attachment point. Ensure that the ropes have sufficient slack to not
strain the wing attachments should a tyre deflate while the aircraft is tied down.
2.
Tie rope to the Tail Tie-down Hole in the Ventral Fin. Secure the opposite end of rope to ground
anchors.
